How to calculate your due date?

Once your pregnancy is confirmed you want to know your due date. Delivery due date is the expected date of delivery of your baby. The average length of pregnancy is 40 weeks or 280 days from the first day of your last period. To know your due date without any calculator help, just add nine months and seven days in the first date of your last period.

For example if the first day of your last period was march 28th, add 7 days then you get date April 4th. Now add nine months you will get January of next year. So your due date would be 4th January of next year.

You can also calculate the date of conception occurs, First trimester end date, Second trimester end date, Third trimester end date.

Generally conception occurs before 2 weeks of your next period due date. So if your period cycle is of 28 days then conception will occur after 14 days of your last period first date.

For example if you had your last period at 28th march then your conception was occurred about after 14 days means at 11th April. Your first trimester will end after 12 weeks means at 20th June. Your second trimester will end after 27 weeks means at 3rd October. Third trimester end date is the same as estimated due date means 4th January.

Total period of pregnancy

  • Post Term: 42 weeks and beyond
