Small, precise instruments for exploring Chinese culture — free, in the browser, no installation. Convert a date to the lunar calendar or find the zodiac animal attached to your birthday.
Culture is best understood by using it.

Every tool runs entirely in your browser and is free to use.
Select any date and instantly see its Gregorian form, its lunar date with leap-month handling, the year's heavenly stem and earthly branch with zodiac animal, the weekday, traditional festivals, and the solar term (jieqi) of the day.
Enter your complete birth date to find your zodiac animal, Chinese name, lunar year, earthly branch, and five-element association. Dates before Lunar New Year are handled correctly.
