Pregnancy Due Date Calculator

When is your baby due?

Enter the date of the first day of your last menstrual period.

How To Calculate Your Due Date

Add 40 weeks to the date of the first day of your last menstrual period. This assumes an average menstrual cycle length of 28 days, so if your average menstrual cycle length is different than 28 days, this calculator will take that into account.
