How to use this tool
Choose a Gregorian date. The browser’s Intl.DateTimeFormat implementation with the Chinese calendar returns the corresponding calendar date. The tool shows the related Gregorian year and cyclical year name when the browser exposes them. A leap month is an extra lunar month and may appear with a special month label. Output and supported date ranges can vary between browsers.
Try these values
February 17, 2026 is Chinese New Year and the first day of the first lunar month in the 2026 calendar year. Dates in January 2026 still belong to the preceding Chinese calendar year.
Look at the month as well as the year
A Chinese calendar year does not begin on January 1. Someone checking a January birthday may still be looking at the previous Chinese year. The converted date and the dual-date month view help you follow where a lunar month begins within the Gregorian month. A leap month repeats a month number and is part of keeping the lunar months aligned with the seasons.
Check an official calendar for an observance
This page uses the Chinese calendar data included with your browser. It is useful for looking up a date, but a holiday or local event may follow a specific published calendar and location. Confirm important observances with that source. If the browser does not support the calendar, the page reports the problem instead of returning an ordinary Gregorian date under a Chinese label.
Common questions
Is the Chinese year the Gregorian year?
Not throughout January and February. Chinese New Year starts a new Chinese calendar year on a different date.
Does this use a downloaded table?
No. It uses the calendar data included with your browser. An unsupported browser receives an explicit message.
Can I use it for official observances?
Confirm important dates with an official local calendar, since regional observance and calendar presentation may differ.
