This interactive due date calculator saves you the bother of all the calculations to arrive at an estimate of when your bundle of joy will enter the world. Each pregnancy is unique and babies can sometimes arrive sooner or later than you expect. A pregnancy generally lasts 40 weeks or 280 days from the date of conception. It is estimated that only about 5% of women deliver on their due date. Obstetricians allow two weeks on either side of the estimated due date and consider a baby on time.
This pregnancy due date calculator will help you estimate the expected due date based on your last menstrual period. The date of conception is considered to be about 2 weeks after the first day of your last menstrual period. 28 days is considered to be the average menstrual cycle. But this can vary from woman to woman. To use this due date calculator, enter the first day of your last menstrual period and the average length of your menstrual cycle.
