Our pregnancy due date calculator will help you to work out when your baby’s likely to arrive, so you can start planning ahead. Most babies arrive within a week of their due date.
To calculate your baby’s due date, enter the first day of your last menstrual period and your cycle length. Because pregnancy is calculated from the first day of your last period, you are technically two weeks pregnant on the date of conception. This due date calculator should only be used as an estimate of your due date. Your baby will come when he or she is ready and a full-term pregnancy can be anywhere between 37 and 42 weeks. Please consult your healthcare professional to confirm your due date or for advice regarding your pregnancy.
