Lunar month lookup
Lunar Month at Conception Calculator
Enter your conception date to find the Chinese lunar month used in the traditional Chinese gender chart.
Find your lunar month at conception
Enter the Gregorian conception date. LunarBabyStory will convert it to the Chinese lunar month used by the traditional gender chart.
What This Calculator Does
The traditional Chinese gender chart uses the lunar month of conception, not the Gregorian month printed on a regular calendar. This tool converts a known Gregorian conception date into the lunar month value used for chart lookup.
How This Differs From the Conception Date Guide
The Chinese Conception Calculator explains conception-date context, LMP and estimate caveats. This page is narrower: it assumes you already have a conception date and only need the Chinese lunar month.
Leap Lunar Months
Some lunar years contain a leap month. When a conception date falls in a leap lunar month, LunarBabyStory shows that status and keeps the chart month number aligned with the site's current V1 leap-month policy.
Use It With the Chart
To read the chart manually, combine this lunar conception month with the mother's Chinese lunar age.
