Guides
Signs use the solar date
Zodiac signs follow the 12 houses based on the sun's orbital position, so they must use the solar birthday to be accurate.
Boundary-day births
If you were born on a sign's start/end date (e.g. May 20 vs. 21), the sign can differ by the sun's exact entry time, so check the precise birth time.
FAQ
Does it use the lunar birthday?
No. Western zodiac signs follow the sun's position, so they use the solar birthday.
Is Ophiuchus included?
It follows the traditional 12-sign zodiac, so Ophiuchus is excluded.
