Yes, your birth time matters (and what to do if you don't know it)

The rising sign — the zodiac sign coming over the eastern horizon at the moment you were born — changes roughly every two hours. It sets your whole house system: which part of your chart is about money, which about relationships, which about work. Get the birth time wrong by an hour and the houses can shift completely.

This is why we ask for the exact time, and why we go to unreasonable lengths with historical timezones. Daylight saving rules in 1985 were not what they are now; a chart computed with today’s rules can be silently off by an hour — wrong rising, wrong houses, wrong everything. Our engine resolves the timezone that was actually in force at your birth moment.

Don’t know your birth time?

First: check your birth certificate, hospital records, or a parent’s memory anchored to something concrete (“just before lunch” beats “morning, I think”).

If it’s truly lost, you still get a real reading. We calculate what doesn’t depend on the clock — your Sun, Moon (almost always), and every planet-to-planet aspect — and we simply don’t write about houses or your rising sign, rather than guessing. A slightly shorter true reading beats a longer invented one, every time.

Ready? The free reading works with or without a birth time.
