FAQ
How are real age and nominal age calculated?
Real age only increments on each full year after birth; nominal age (xu sui) counts you as 1 at birth plus one each Lunar New Year — here computed as current year minus birth year plus one. Legal age always uses real age.
Is the zodiac year by Lichun or Lunar New Year?
This tool uses the calendar birth year (e.g. 2026 is the Horse year) for quick reference; traditional astrology may use Lichun — double-check the lunar calendar if born near New Year.
What about Feb 29 birthdays?
In non-leap years there is no Feb 29, so the countdown uses Feb 28; the exact age (years/months/days) is unaffected.
Is my birthdate uploaded?
No. Everything is computed in your browser; dates never leave your device.
