What this tool does
Free online Chinese lunar calendar converter. Enter any Gregorian (solar) date between 1900-01-31 and 2100-12-31 and instantly get the matching lunar (农历 / nongli) date, including the stem-branch year name (干支 — 甲子, 乙丑, …), the zodiac animal (生肖 — Rat, Ox, Tiger, …), the 24-solar-term name if your date is a jieqi, and the traditional Chinese festival if it lands on one (Chinese New Year, Lantern Festival, Dragon Boat, Mid-Autumn, etc.). Reverse mode lets you pick a lunar year/month/day (with leap-month toggle) and get the Gregorian date back — useful for finding when your lunar birthday falls in any given year. All computation runs in your browser using the public Hong Kong Observatory / Purple Mountain Observatory ephemeris table; no network, no tracking.
