Pregnancy calculator

Calculate your due date

Use this handy pregnancy calculator to work out the rough birth date for your baby.

To calculate your baby due date:

1. Just enter the date your last period started.
2. Then the number of days you usually have from one period starting to the next period starting. (This is the length of your monthly cycle and is usually about 28 days.)
3. Then press the 'calculate my due date' button to find the birth date.

Please remember fewer than 5 percent of women have their baby on their actual baby due date.
This pregnancy calculator is just a guide to the due date.

What was the date of the first day of your last period?
