Pregnancy date online calculator

App description

The expected date of birth, which is the date the pregnant
woman is expected to produce. The expected date
of delivery is not the exact date of delivery. Scientists
have estimated that only about 53% of women give
birth on the day of the due date.

Since it is difficult for every pregnant woman to accurately
judge the time of conception, it is medically
prescribed that the expected date of birth is calculated from
the first day of the last menstrual period.
The total pregnancy is 280 days, 10 pregnancy months (28 days
per pregnancy month).

Usage example

The time of last menstruation is: January 1, 2019
