I don’t know my birth time
You can still get your chart. Here’s what changes without a time, and how to add it later.
Last updated November 10, 2026
No birth time, no problem. Tick I don’t know my birth time when you enter your details and Aurae will build your chart without it.
What changes
- Your planets’ signs are still exact.
- Your houses use your Sun sign as the 1st house (solar houses).
- Your Rising sign isn’t shown, because it depends on the exact time.
The Moon moves about 13° a day, so if it changed sign on the day you were born, your Moon sign can depend on the time too.
Adding your time later
If you find your birth time (a birth certificate or a family member are good places to look), add it in Profile → My Charts → Correct birth details. Your chart is recalculated, and your Rising sign appears.
