Chinese Baby Due Date Calculator

The Chinese baby due date calculator helps determine your expected delivery date based on the Chinese lunar calendar system, which is different from the Western Gregorian calendar. This tool accounts for the 280-day pregnancy period used in traditional Chinese medicine and cultural practices.

How to Use This Calculator

To calculate your Chinese baby's due date:

Enter the date of conception or the first day of your last menstrual period (LMP)
Select whether you want to use the conception date or LMP date
Click "Calculate" to see your estimated due date

The calculator will display your Chinese due date, which is typically 280 days after conception or 300 days after the first day of your last menstrual period.

Chinese Due Date Calculation Method

The Chinese due date calculation is based on traditional Chinese medicine principles rather than Western medical standards. The key differences include:

Pregnancy duration: 280 days (instead of the Western 266 days)
Conception timing: The first day of menstruation is considered the start of pregnancy
Due date calculation: 280 days after conception or 300 days after the first day of last menstruation

Formula

If using conception date:

Due Date = Conception Date + 280 days

If using last menstruation date:

Due Date = Last Menstruation Date + 300 days

This method is commonly used in Chinese cultural practices, family planning, and some traditional medical approaches.

Example Calculation

Let's say you had your last menstruation on January 1, 2023. Using the Chinese method:

Start with January 1, 2023
Add 300 days (280 days after conception would be used if you knew the exact conception date)
Result: November 6, 2023

This would be your estimated Chinese due date based on the first day of your last menstruation.
