FAQ

AstroPrognostic is a professional online astroprocessor: it computes natal charts, transits, synastry, progressions and solar/lunar returns on the Swiss Ephemeris. It gives precise astronomical data and chart wheels, without interpretations.

Yes — you can create an account and build charts for free. Some advanced astrologer services (consultations, rectification, courses) are paid and provided by partners.

Positions are computed on the Swiss Ephemeris, the industry standard, down to the arcsecond, with correct historical time zones and daylight saving time for any date and place.

Six house systems (Placidus, Koch, Whole Sign, Equal, Regiomontanus, Campanus), the five major aspects and optional minor aspects with configurable orbs.

Yes — and it is the most convenient way to work from your phone. AstroPrognostic opens as a full Telegram Mini App via @westastro_bot: automatic language detection, one-click sign-in, every chart technique — no separate app to install.

Yes. Smart notifications work over email and Telegram: a daily transit digest in Telegram, appointment reminders and personal alerts for important transits (for example, "warn me 3 days before Mercury turns retrograde") — sent by email and/or Telegram, your choice. Turn them on in account settings or on a chart's calendar page.

No. The content is informational and for entertainment. It is not advice; do not make medical, financial, legal or other important decisions based on it.

The site is available in 22 languages, including English, Russian, Ukrainian, Spanish, French, German, Arabic, Chinese, Japanese and more.

Yes — charts can be exported to PNG and PDF.

We collect only the minimum required to cast precise charts: name, date, time and place of birth. Your email is used strictly for system notifications — no spam. We use Google Analytics and Google Console in an anonymized way. Your saved charts and client data are strictly confidential and securely protected.

You are in full control of your data. To delete a specific chart, click the Trash icon in the chart's action menu. To permanently delete your entire account and all saved data, go to Account Settings -> Delete account and confirm.

If the exact time is unknown, you can switch to Cosmogram mode (hides the house cusps) by pressing the C key on your keyboard or using the display settings. However, accurate forecasting requires an exact time. You can book a Rectification service from a professional astrologer on our platform, or use our AI Rectification tool to narrow down the time yourself based on life events!

Yes! Astroprognostic automatically calculates 24 major fixed stars. Tight conjunctions (up to 1° orb) are marked with a ✦ symbol on the natal wheel. We also calculate the True Lilith, Lunar Nodes, Vertex, East Point and Part of Fortune.

Yes, we added keyboard shortcuts to save you time: N for Natal, T for Transits, P for Progressions, S for Solar returns, C to toggle Cosmogram mode, and Q/E to quickly flip through your charts. You can see the full list by clicking the keyboard icon (⌨️) in the bottom left corner of the menu.

Core features (Swiss ephemeris, natal charts, transits, synastry) are completely free. The Pro plan is for practicing astrologers and offers White-labeling (your logo on PDF reports), smart notifications, iCal transit subscriptions, Telegram digests, and no watermarks on exports.

We are constantly improving the service! You can write to our Telegram support bot or use the feedback form on the site. You can even attach a screen recording (up to 100 MB) to your message to show exactly what's happening.

Our AI does not use pre-written paragraphs. When you use the AI-reading or Chat features, the algorithm analyzes the strict astronomical data of your specific chart (coordinates, exact aspects, receptions, configurations) to generate a unique, deep synthesis — just like a real astrologer would.

The "Electional" section: set a date range (up to 31 days) and a place — the site finds windows with no void-of-course Moon, no retrograde Mercury, and (optionally) the Moon in a chosen sign or in a harmonious aspect to your natal chart. Open →

The "Horary" section: cast a chart for the moment the question became clear to you. The site shows the Moon's next aspects, its void-of-course status, and radicality warnings — the significator reading itself is the astrologer's job. Open →

The "Rectification" section: enter dated life events — the site highlights the time that fits them best and ranks candidates in a numeric report (plus an AI explanation of that report in words). Create a chart first →

The "Transits" section on your chart — exact aspects from current planets to natal points, with the exact date and time. For a list over a range of dates, use the "Calendar" layer. Create a chart first →

The "Solar return" section — a chart for the moment the Sun returns to its natal point each year; the return's own angles and houses show the year's emphasis. Create a chart first →

"Directions" (symbolic, 1°=1 year) or "Progressions" (secondary, day-for-a-year) — two classical slow-timing techniques. Directions are more formula-based (realization windows), progressions are about inner maturation. Create a chart first →

The "Synastry" section: pick another chart of yours, or a celebrity from the database (⭐) — the site shows inter-aspects and whose planets fall into whose houses. Create a chart first →

The "Relocation" section: the same planets, but angles and houses recalculated for the new place, plus lines on a world map showing where each planet lands on an angle. Create a chart first →

The "Saturn return" section — all three Saturn returns across a lifetime (~29, ~58, ~88 years) plus the in-between squares/oppositions, one list of dates. Create a chart first →

The "Lunar calendar" section — a month grid: which sign the Moon is in each day, ingresses, new/full moons and eclipses. Create a chart first →

"Calendar" (a list of exact hits over a date range) or "Time machine" (a date slider that visually highlights exact aspects). Create a chart first →

On the natal chart page — the "Download" menu: a PNG wheel, a PDF wheel, or a full PDF report (wheel + every table). On the Free plan, PNG carries a watermark. Open →

The "Share" menu on a chart — a public or one-time link to view without logging in. On the Pro plan you can upload your own logo in your account ("White-label logo" section) — it appears on the PDF report, the booking page and the public chart link instead of the service's brand. Open →

Subscribe to the transit calendar via iCal ("Share" → "Subscribe") — events land straight in Google/Apple Calendar. In Telegram — a daily transit digest (account → notifications). Automations require the Pro plan. Open →

The "Week board" (linked from the charts list page) — a single chronological list of exact transits across ALL your charts, with a "client" column. Open →

The "💬 Ask the chart" button on the chart page (and on most technique pages) — the chat answers STRICTLY from your computed data, without making anything up. Open →

The "✨ AI reading" button on the chart page — a structured text (elements and dominants → core personality → configurations → life spheres → strengths and tensions), built from the same computed data as the tables on the site. Open →

The "Harmonics" section — a chart where every longitude is multiplied by N (H5, H7, H9…) and reduced modulo 360°. Create a chart first →

The sky at the exact moment and place of birth — planets, houses, aspects, special points. The base chart every other technique builds on.

✅ Helps with:

• Shows the original positions of planets, signs, houses and aspects at birth.
• The anchor point for all prognostic techniques — transits, progressions, returns are all computed relative to it.
• Surfaces configurations (T-square, stelliums), essential dignities, house rulers and "signification", house#house formulas.

✕ Can't do:

• Doesn't show WHEN events happen — for timing you need prognostics (transits, directions, progressions, returns).
• Without an accurate birth time (ideally to the second) the Ascendant, MC and house cusps are unreliable — the angles move roughly 15′ per minute of time.

→ What to use next:

• Birth time unknown or doubtful → "Rectification".
• What's active RIGHT NOW → "Transits" or "Periods".

Where the planets are "now" (or on a chosen date) relative to natal points — how the current sky activates the natal chart.

✅ Helps with:

• Precise timing: the moment an aspect becomes exact (to the minute).
• A calendar of exact hits over a period, slow-planet cycles (Jupiter/Saturn returning to their own natal point), lunations and eclipses, retrograde loops.
• Subscribe to events in Google/Apple Calendar (iCal link).

✕ Can't do:

• Doesn't explain inner development of the personality — that's progressions.
• Doesn't by itself say whether an event matters to the person — that's decided by natal context (formulas, house rulership), not the mere fact of a transit.

→ What to use next:

• The theme of one whole year → "Solar return".
• Inner maturation of a theme rather than an outer trigger → "Progressions".
• The exact hour of an event on a slider → "Time machine".

A chart for the exact moment the Sun (solar — yearly) or Moon (lunar — monthly) returns to its natal longitude.

✅ Helps with:

• The theme of the whole year (solar) or month (lunar) — emphasis from the return's own angles and houses.
• The solar return can be cast for a DIFFERENT place (relocation) — where you spend your birthday matters.

✕ Can't do:

• Doesn't show WHEN inside the year/month a specific event fires — the return is a static snapshot; for timing inside the period you need transits.
• The "current" solar return is the PREVIOUS birthday, not the next one, if this year's birthday hasn't happened yet.

→ What to use next:

• Timing inside the year/month → "Transits".
• Where to spend the birthday → "Relocation".

Every natal planet and angle shifts together by an arc of "1° = 1 year lived" — the classic symbolic long-range timing technique.

✅ Helps with:

• Long-range timing of life themes (realization windows: up to 5 years for the Sun/Moon, 3 years for other planets).
• Direction formulas — which natal house#house links a directed contact switches on.

✕ Can't do:

• Gives slow, year-scale timing, not an exact date.

→ What to use next:

• Narrow the window to an exact date → "Transits".
• Compare with the other "day-for-a-year" technique → "Progressions".

The chart for day N after birth = year N of life ("day for a year") — the inner psychological unfolding of the chart.

✅ Helps with:

• The progressed Moon (an emotional cycle of ~27-28 years) — major inner shifts.
• Progressed aspects to natal points, progressed Sun/Moon sign changes as maturation milestones.

✕ Can't do:

• Doesn't give dates as sharp as transits — this is inner, not outer, timing.

→ What to use next:

• An outer trigger for an inner progressed theme → "Transits".
• Formula-based timing → "Directions".

Comparing two natal charts: inter-aspects between both people's planets, and house overlays (whose planets fall into whose houses).

✅ Helps with:

• Shows the points of attraction and friction between two charts.
• You can compare your chart with a celebrity from the database (⭐ on the synastry page).
• AI reading and AI chat for a specific pair (grounded in the same computed data, no guessing).

✕ Can't do:

• Synastry itself doesn't merge two charts into one "relationship chart" — that's a separate technique, "Composite · Davison" (linked on the synastry page when the partner is one of your own charts).
• Doesn't predict the outcome of a relationship — only describes the dynamics of the contacts and overlays.

→ What to use next:

• How a specific day plays out for the couple → "Transits" on each partner's own chart.

Conjunctions between natal planets/angles and significant fixed stars (default orb 1°).

✅ Helps with:

• Adds a traditional layer to the chart's focal points (Ascendant, MC, luminaries).

✕ Can't do:

• Only conjunctions count — traditionally the only meaningful aspect for stars.
• The catalogue is a curated list of ~24 significant stars, not the whole sky.

→ What to use next:

• When a transiting planet lands exactly on a star → "Calendar" or "Transits".

A chronological list of exact transit hits (aspects) over a chosen date range.

✅ Helps with:

• Plan a period (consultations, decisions) around dates of specific aspects.
• Subscribe to events in Google/Apple Calendar via an iCal link (automation — Pro tier).

✕ Can't do:

• Doesn't rank aspects by importance itself — that's decided by natal context (formulas, house rulership), not the calendar.
• Limited to the chosen date range, not a single lifetime list.

→ What to use next:

• The whole picture at one specific moment → "Transits".

A workshop for narrowing down an unknown or doubtful birth time from life events: a ±N-minute time slider plus highlighted matches between directed hits and event dates.

✅ Helps with:

• Narrows the likely birth-time range from the dated events you enter.
• Auto-ranks candidate offsets by how many events they match (a numeric report).
• AI reading — a written explanation of the finished numeric report, not a from-scratch guess.

✕ Can't do:

• Doesn't give a 100% exact time without a reliable source — a birth certificate or parents' memory always outranks the calculation.
• The fewer and vaguer the events entered, the lower the accuracy of the result.

→ What to use next:

• After narrowing the time — lock in the angles → "Natal chart".
• Check a current question on the refined chart → "Horary".

The inverse problem to "house formulas": finds WHEN in the future a natal link (e.g. "10#4") gets activated by a symbolic direction.

✅ Helps with:

• Finds specific ages/dates when a chosen formula activates within a given age window.

✕ Can't do:

• Only works with formulas already present in the natal chart — doesn't create new themes.
• Direction-based timing is approximate (a window in years), not an exact date — for the exact date inside the window you need transits.

→ What to use next:

• The exact day inside the found window → "Transits".
• The natal formulas themselves → the "House formulas" layer on "Natal chart".

Two classical "life epoch" systems: annual profections (which house is "active" this year) and Persian firdaria (which planet "rules" the period).

✅ Helps with:

• The general THEME of the current year/period without building a separate chart.

✕ Can't do:

• Doesn't give an exact date inside the year by itself — it's a background theme of the period, not an event.

→ What to use next:

• Overlay actual transits on the period's active theme → "Transits".

Every pass of Saturn over its own natal point across a lifetime: three returns (~29, ~58, ~88 years) plus the in-between squares/oppositions ("seven-year" milestones).

✅ Helps with:

• See the dates of major age milestones ahead of time (the first return — the classic ~28-30 years).

✕ Can't do:

• Doesn't replace a full transit review — it only shows Saturn's aspects to ITSELF, not to the whole chart.

→ What to use next:

• Saturn against the whole chart on a specific date → "Transits".

A month-by-month grid: which sign the Moon is in each day, ingresses, new/full moons and eclipses.

✅ Helps with:

• Plan a rhythm around Moon phases and signs for the month ahead.

✕ Can't do:

• Not personalised to your natal chart automatically — which of your houses the transiting Moon activates is shown by "Transits", not this calendar.
• An overview grid, not a tool for picking a specific moment (for that — "Electional").

→ What to use next:

• Pick one specific favourable moment, not just a sign → "Electional".

A chart where every longitude is multiplied by N and reduced modulo 360° — surfaces resonances invisible in the ordinary chart (per John Addey's classic harmonic theory).

✅ Helps with:

• An alternative view of the chart through a specific harmonic (H5, H7, H9…).

✕ Can't do:

• Not part of the core rectification/horary workflow — a supplementary technique.

→ What to use next:

• The baseline chart to compare against → "Natal chart".

A date slider under the wheel: the transit ring rotates in real time, exact aspects light up as they're reached.

✅ Helps with:

• Visually "scrub" a period and see exactly where an aspect is exact, without reading a calendar line by line.

✕ Can't do:

• A lightweight calculation (major aspects only, no nodes/Lilith) — for the full list use "Transits" or "Calendar".

→ What to use next:

• Exact orbs and the full body list → "Transits".

The same sky as at birth, but angles and houses recalculated for a DIFFERENT place, plus lines on a world map showing where planets sit on an angle (Asc/MC/Dsc/IC).

✅ Helps with:

• Shows how moving or travelling shifts the chart's emphasis.
• Planetary lines across the whole world map — where each planet is "on an angle".

✕ Can't do:

• Doesn't auto-generate a ranked list of "best cities" — the lines are geometry, not a ready-made "move here / don't" recommendation.
• City scoring for solar returns (the solar-return relocator) is an open task, waiting on the owner's rules for a "good" solar return.

→ What to use next:

• A specific return date somewhere else → "Solar return" with relocation.

Horary astrology — a technique where the chart is cast NOT for a birth, but for the MOMENT a question is clearly understood by the astrologer or client. Tracing back to William Lilly (17th century): the arrangement of the sky at the moment the question crystallizes is read as the structure of its answer.

✅ Helps with:

• Builds the chart of the moment of the question — a wheel and tables, just like a natal chart.
• The Moon's next exact aspects before it leaves its sign — the Moon is traditionally a key co-significator of the querent, and its next contact is often read as how the matter unfolds.
• The Moon's void-of-course status — the classic marker that "nothing will come of it" at this particular moment.
• Radicality badges — whether this specific moment can even be trusted: Ascendant in the very first or last degrees of a sign (asked "too early" or "too late"), Saturn in the 7th house (the traditional warning about the astrologer's OWN error of judgment), Moon in late degrees.
• A saved-questions log — revisit any horary later and check it against how events actually unfolded.

✕ Can't do:

• The site does NOT give a ready-made verdict ("yes"/"no", which house rules what in YOUR question) — a deliberate decision: a full horary reading needs traditional significator technique, reception, antiscia, translation of light — a practicing astrologer's judgment call, not automation.
• Horary answers a SPECIFIC, clearly formulated question at the moment it's understood — it is NOT a general forecast of "what will happen", and not a substitute for natal prognostics.
• Accuracy depends entirely on the MOMENT: what matters is when the question genuinely crystallized (classically, when the astrologer received and grasped it), not when someone happened to open the page. A random time gives no valid horary.

→ What to use next:

• A question about TIMING ("when is best to do X") for something not yet underway → "Electional".
• A question about how an already-ongoing process in someone's life will unfold (not a question of the moment) → that person's own "Natal chart" + "Transits"/"Directions", not horary.
• You have the querent's own chart → cross-check the horary against their "Natal chart" and "Transits" for the same moment.

Electional astrology — picking a favourable MOMENT to start something important (a wedding, launching a business, signing a contract, surgery, etc.). The logical mirror of horary: horary reads a moment that already happened, electional engineers a future one.

✅ Helps with:

• Scans a date range (up to 31 days) for a chosen place on an hourly grid.
• A "no void-of-course Moon" filter — the baseline condition for almost any election.
• A "no retrograde Mercury" filter — traditionally important for deals, signatures, negotiations, purchases and travel.
• A "Moon in a desired sign" filter — traditionally the transiting Moon's sign sets the "tone" of the undertaking.
• An optional check for a harmonious aspect from the transiting Moon to the natal Sun/Moon of a SELECTED chart — personalised to a specific person, not an abstract moment.
• Ready-made windows found, each linked to "Transits at this moment" for further manual review of the full sky.

✕ Can't do:

• Does NOT check the full traditional electional procedure end to end (the matter's ruler on the Ascendant, no malefics on critical points, exact significator receptions, etc.) — this is a PRIMARY mechanical filter (VoC / retrograde Mercury / Moon sign / natal aspect), not a substitute for a professional electional consultation.
• Does NOT apply rules specific to the TYPE of event — weddings, surgery, launching a business each have different traditional criteria in the literature; the site offers ONE universal filter set, not a separate one per event type.
• One scan is capped at 31 days — for a longer planning horizon you need to scan in chunks.

→ What to use next:

• Once candidate windows are found → open "Transits" for each moment and manually review the full chart (every planet's aspects, house placements).
• The event is already scheduled and you want to know how it will go (not pick a time) → "Horary" for the moment the question crystallized, or "Transits" for the already-scheduled date.
