Pregnancy Due Date Calculator
When is your baby due? If you’re having trouble remembering dates and counting up the days on your fingers and toes, don’t worry – use our pregnancy due date calculator.
Simply use the drop-down menus below and click ‘calculate’.
To work out the length of your menstrual cycle, count from the day your period normally starts to the day before your next period. The average cycle is 28 days.
REMEMBER: This date is just an estimate; only about 4% of babies are born on their due date.
We can give you a rough guide of when to expect your baby – although we know all too well that baby will arrive when he is good and ready.
You will also receive a dating scan from your midwife that will give you a more accurate guide to your due date. From the date of your last period, pregnancy normally lasts from 37 to 42 weeks. When the time comes, make sure you are prepared!
