Why Use This Tool?
Chinese New Year dates, lunar birthdays, festival planning, Gan-Zhi astrology — they all live in the lunar calendar, which refuses to line up with the Gregorian months. This converter translates both directions: pick a Gregorian date to get its lunar equivalent, or enter a lunar date to find the Gregorian day.
Results include the lunar month and day in Chinese numbering, the zodiac year, and the Gan-Zhi (stem-branch) designations used in traditional calendars. Leap months, the classic trap of lunar conversion, are handled explicitly with a checkbox.
How It Works
- Enter a Gregorian date to read its lunar equivalent, or a lunar date to go back.
- Watch for leap months — tick the box only when the lunar year actually has one.
- Read the zodiac and Gan-Zhi designations alongside the date.
Frequently Asked Questions
How do I convert Gregorian to the lunar calendar?
Pick any date from 1900 to 2100 above and convert — you get the lunar year, month, and day in Chinese numbering, plus the zodiac year.
What is a leap month in the lunar calendar?
The lunar year is about 11 days short of the solar year, so roughly every third year adds a repeated month to catch up. Only those years have a leap month.
Which Chinese zodiac year am I in?
Convert your birthday and read the zodiac line — but note the lunar year starts at Chinese New Year, so January birthdays often belong to the previous zodiac animal.
Tips & Things to Watch
- Lunar birthdays shift earlier each Gregorian year — convert, don't guess.
- Chinese New Year always falls on the new moon between Jan 21 and Feb 20.
- Day 30 doesn't exist in every lunar month — small months end at day 29.
