What makes these calculators different
- Your birthplace, handled properly. Pick your city and we apply its historical time zone, daylight saving and true solar time automatically.
- Honest about edge cases. Born near a solar term, late at night, or between the Start of Spring and Chinese New Year? We show you both versions of your chart and explain why other sites may differ.
- Explained in plain English. Tap any character to see what it means in your chart. No jargon without a translation.
- Private by design. Every calculation runs in your browser. There's no account, and we never receive your birth details.
