Pregnancy Due Date Calculator

Wouldn’t it be wonderful if we could accurately predict when your little bundle of joy will arrive? Calculating your baby due date can be so confusing to figure out- so many numbers to crunch, days to add or days to subtract.  Our pregnancy due date calendar is exactly what you need to make it easy!
 

How to use our Pregnancy Due Date Calculator

Our Pregnancy Due Date Calculator is a fun tool you can use to get an estimated baby due date for your baby's arrival. All you need to do is type in the date of your last period into the pregnancy calculator below, and the due date calculator will do the rest! 

Although babies rarely stick to a schedule, usually a full-term baby will arrive anywhere from 37 to 42 weeks from your conception date. Ovulation, when your body releases an egg from your ovaries, happens approximately 2 weeks after the start of your last period, this is the time you conceive, or fall pregnant. As it’s difficult to know your ovulation and conception date exactly, most baby due date calculators, like our Pregnancy Due Date Calculator below, use the first day of your last period, and add 280 days (40 weeks) to that day, to estimate your baby due date. 

Menstrual cycles can vary, so keeping track of your menstrual cycle will help you identify the date of your last period. If you haven’t been tracking your periods, it’s all good, make an educated guess based on an average 28 day cycle, and the due date calculator will give you your baby due date based on this best guess.  If you are on an IVF journey, your healthcare professional will be able to provide you with the date to use in a pregnancy due date calculator, for example the date of egg fertilisation, or date of embryo transfer.

To get a more accurate baby due date, an ultrasound conducted by your doctor will be able to confirm your baby’s age and estimated due date.
