Birthday Match
Same date and month, any year. Enough to share a wall and a group.
Swiss Ephemeris accurate
Find your birth twin
Someone was born the same moment as you. Twinbat is how you find them.
How matching works
A score alone is not enough to earn a name. A “Time Twin” badge requires an actual birth-time match, not a high number from somewhere else — so if your birth time is unknown, you will never be shown to a stranger wearing a badge that claims otherwise.

Your signs
Most apps give you one sign from your birth date. Twinbat computes the whole chart: where the Sun and Moon actually were, which sign was rising over your birthplace at your birth minute, and the nakshatra your Moon sat in down to the pada.

The engine
Every position in Twinbat comes out of an ephemeris, not out of a language model. The AI receives the finished chart as data and interprets it — it is never asked where Saturn was, because guessing that is how astrology apps quietly become fiction.
Swiss Ephemeris
Positions from the same ephemeris professional astrology software runs on — arc-second accurate, not a lookup table.
Lahiri ayanamsa
23°51′11″ at J2000, matching the Indian Astronomical Ephemeris. The sidereal zodiac, computed rather than approximated.
Real timezones
Your birthplace resolves to its historical offset. A 1985 Indian birth is IST; a July birth in New York is EDT, not EST.
Vimshottari dasha
The full 120-year cycle with antardasha sub-periods, so a reading knows which chapter of your life you are actually in.

Soft Words, Clear Limits
Today is emotionally social but mentally busy. Moon in Cancer in Pushya puts the feeling tone on care and belonging, while a Venus period makes connection especially loud.

A daily reading, from your chart
Anchored in your moon sign and your active dasha lord, with one action you can finish today and one pattern to avoid.
Ask about your own pattern
Not a chatbot with a horoscope pasted on. It answers using your placements, and tells you when a question needs a real professional.
Twin comparison
Two charts read side by side — emotional similarity, communication, conflict triggers. Both people have to consent before it runs.
A private journal that answers
Write the real thing. It reflects rather than reassures, and if an entry reads as crisis it surfaces real helplines, never a moderation warning.
AI readings are for self-reflection and entertainment. They are not medical, legal, financial or emergency advice.
Privacy
Not private after you find the setting. Private from the moment you sign up, with nothing about the moment you were born visible to anyone until you decide otherwise.

Questions
The things people actually ask
What actually is a birth twin?
Someone born close to you in time and place. Twinbat scores that across six levels — from sharing a date, up to sharing the date, the year, the hour and the city. The rarer the overlap, the higher the badge.
Is the astrology real, or decorative?
It is computed. Charts come from Swiss Ephemeris using the Lahiri ayanamsa — the same ephemeris professional astrology software runs on. You get sidereal sun, moon and lagna, nakshatra and pada, navamsa, planetary dignities, aspects and a full Vimshottari dasha timeline. The AI never calculates a chart; it only interprets the one the engine produced.
What if I don't know my birth time?
You still get your sun sign, moon sign and nakshatra. What you will not get is a lagna, because there isn't one without a time — and you will never be shown to anyone as a Time Twin. Twinbat will not make a claim your data cannot support.
Who can see my birth details?
Nobody, by default. Your birth time, exact birthplace, birth year and current location are private until you change that. Match reasons say "born within the hour" — never the actual time.
Do I have to share my location?
No. Location discovery is opt-in, both sides have to enable it, and it works on approximate city rather than live position.
Can I talk to anyone on here?
No — and that is deliberate. There is no open messaging. You can only chat with someone you matched with and who accepted your connection request.
