Due date calculator
Pop in one date and we will estimate when your little one is due, how far along you are, and how many days there are to go.
An estimate only. Most babies arrive within two weeks either side of the date. Your midwife or doctor always has the final word.
Common questions
The common method counts 280 days, or 40 weeks, from the first day of your last period. If you know your conception or IVF transfer date, we count 266 days from there instead. Both are estimates, since every pregnancy is a little different.
