Calculate your due date

Pregnancy starts with the date of the last period. Birth date is calculated by adding 280 days, or 40 weeks, to the first day of the last period. Pregnancy itself lasts actually for 266 days, or 38 weeks, and starts with the day of conception. Difference of 14 days represents the period of the first day of the period to the ovulation when the conception occurs.
