Calculate Your Due date

Pregnancy Due Date Calculator

Pregnancy, on average, lasts 267 days (38 weeks) from conception. If you positively know your conception date, you can add 267 calendar days to it to calculate your pregnancy due date.

The following formulas can also tell your Expected Due Date :

Date of the first day of your last period + 281 days = due date

or

Date of the first day of your last period + 7 days - 3 months = due date

The due date calculation methods here are based on the average 28-day cycle.
