Due Date Calculator. This interactive Due Date Calculator will help you estimate the date your baby will arrive. Pregnancy usually lasts 280 days (40 weeks) from the first day of the woman's last menstrual period. This calculator is a general guide: every pregnancy is unique, and sometimes babies arrive sooner or later than expected. Always talk to your health care provider about your due date. Once you're pregnant, be sure to have regular checkups by a doctor, certified nurse-midwife or other health care professional during the course of your pregnancy.
