Due date Calculator
Most pregnancies last around 40 weeks (or 38 weeks from conception), so typically the best way to estimate your due date is to count 40 weeks, or 280 days, from the first day of your last menstrual period (LMP). Calculate your due date based on your LMP before booking into Cork University Maternity Hospital.
*Average length of cycles is from first day of your period to the first day of your next period. Ranges from: 22 to 44. Leave 28 if unsure.
