For the Expected Delivery Date

To get the value, nine months and seven days is added to the LMP inputed

For the Gestational age

The day number of both the LMP and the current date are extracted e.g the day number for January 5th 2024 is 5 because it is the 5th day out of 365 days in a year, then the LMP is subtracted from from the current date. The result is divided by seven , converting it to weeks.

Note:
LMP - Last Menstrual Period

Calculate Delivery date and gestational age by inputing your last menstrual period only
