How to Convert — Gregorian to Lunar
- Open the Mini Lunar Converter.
- Enter your Gregorian date (YYYY-MM-DD).
- Click convert. You’ll see the lunar year, month, day, and weekday.
- Check if the month is flagged as leap.
- If your date is between Jan 1 and Li Chun, note that your BaZi year is the previous one.
For quick lookups, use our Chinese New Year tables alongside Li Chun.
How to Convert — Lunar to Gregorian
- Open the Mini Lunar Converter.
- Select “Lunar → Gregorian.”
- Enter the lunar year, month, and day (specify leap month if relevant).
- Click convert. You’ll get the Gregorian date and weekday.
This helps verify birthdays, festivals, and BaZi chart dates.
Common Cases to Watch
- Near Chinese New Year: Always confirm with CNY tables and Li Chun.
- Leap Months: If born in a leap month, your lunar birthday repeats differently from festival tracking.
- Old Records: Historical birthdays may use regional lunar variants (e.g., Thai lunar calendar coming soon).

FAQs
How do I convert a Gregorian birthday?
Use the Mini Lunar Converter. Enter your Gregorian date and get the lunar equivalent.
What if my birthday is near Chinese New Year?
Confirm with CNY tables and Li Chun. BaZi uses Li Chun, not CNY, as the year boundary.
How do I handle leap months?
The converter will mark if a date falls in a leap month. For BaZi or festivals, keep that distinction clear.
