How to calculate your due date

calculating your due date


One of the most important to thing to a woman after confirming that she is pregnant is to know when the her due date. Manually calculating due date is quite easy if you can remember your first day of your last menstrual period. Simply add 9 months and 7 days to the first day of your last menstrual period and the sum date is your estimate due date.

Let’s say for example the first day of your last normal period is March 1st, just add the 9 months and 7 days and you’ll get your estimate due date. Add the 7 days to March 1 to get April 8, then add the 9 months to March 8 so that would be equal to December 8. So December 8 would be your estimate date of delivering your baby.

The average pregnancy is 40 weeks or 280 days from the very first day of menstrual period. But remember that this calculating technique is just an estimate. In fact only 5 % of mothers deliver their babies on the exact calculated due date. This means that your baby can be born a few days later or earlier than the expected due date.
