It's one of the most common questions. The short answer: you can calculate an approximate chart, but some elements may vary with the time. It's worth knowing which ones before drawing conclusions.

What can change with the time
The Moon is the fastest planet: it changes gate roughly every ten hours. The Sun moves about one degree a day, so its line —and therefore your profile— can change within the same day. If a Moon gate completes a channel, your definition, authority and even type can change.
What usually stays the same
The slow planets (Jupiter, Saturn, Uranus, Neptune, Pluto) barely move in a day, so much of the chart is identical for any time that day. Our free calculator lets you tick 'I don't know my birth time' and shows an approximate result.
How to find your birth time
- ✦Your long-form birth certificate, which often includes the time.
- ✦Hospital records.
- ✦Baby books, family records or photos from those days.
Frequently asked questions
Can I know my type without my birth time?+
Often yes, but not always: if the Moon or another planet completes a channel depending on the hour, your type can change. Confirm it with your real birth time.
What time should I enter if I don't know it?+
Tick 'I don't know my birth time' in the calculator and treat the result as approximate.
