Find Out When Your Baby Is Due

Knowing your due date is one of the first exciting steps in your pregnancy journey. Our pregnancy due date calculator makes it easy to estimate when your baby will arrive, helping you prepare for the months ahead.
Whether you conceived naturally or through IVF, this tool can calculate your estimated due date using the first day of your last menstrual period (LMP), your conception date, or your IVF transfer date – fertilisation.

How to Calculate Your Due Date - Pregnancy Due Date Calculator

Most pregnancies last about 40 weeks (or roughly 280 days) from the first day of your last period (date of your last period). Our pregnancy calculator uses this timeline to provide your estimated due date. You can enter:

Last menstrual period (LMP)

Conception date (if known) (Date of conception)

IVF transfer date – day 3 or day 5 embryo transfer

You can also confirm your due date through an ultrasound in early pregnancy. This is especially helpful if your menstrual cycle length is irregular.

Why Knowing Your Due Date Matters

Your baby’s due date helps you:

Schedule prenatal check-ups and ultrasounds

Plan maternity leave and family arrangements

Track your weeks pregnant and key pregnancy milestones

Monitor growth and development in each trimester

Be aware of signs that may require early medical care

You can also confirm your due date through an ultrasound in early pregnancy. This is especially helpful if your menstrual cycle length is irregular.
