Quick guide
What can Gregorian ↔ Lunar Calendar help you do?
Convert dates between Gregorian and Chinese lunar calendars for 1901-2100, with sexagenary year and zodiac.
Best for
Use this to cross-check a single Gregorian and Chinese lunar date, together with the year stem-branch name and zodiac animal. It can help organize traditional date records, but is not a monthly calendar, auspicious-day selector or personal fortune-telling chart.
How to use it
Choose Gregorian-to-lunar or the reverse. The Gregorian field advertises years 1901 through 2100; lunar inputs use those years, months 1 through 12 and days 1 through 30. Check Leap only for an actual leap month in that year, then convert and wait for the component.
How to read the result
Four outputs show the Gregorian date, lunar date, year stem-branch and zodiac animal. The stem-branch output covers only the year, not a complete birth chart. Lunar months do not all contain 30 days. Calendar names and date units remain Chinese even in the English interface.
Privacy and limits
The first valid conversion downloads lunar-javascript 1.7.3 from jsDelivr, then processes dates in the browser. This widget does not append entered dates to a lookup request or save them in browser storage. Loading the external script still contacts a CDN, so the initial operation is not fully offline.
Today uses the device local date, so incorrect device date or timezone settings still affect the input. Invalid lunar dates may be reported as component-loading failures, with older results visible; leap-month text may also be duplicated. Confirm successful conversion before using important date records.
