What is the Pregnancy Due Date Calculator?
Enter the first day of your last menstrual period (LMP) and get your estimated due date using the standard 280-day (40-week) rule, plus your current gestational age in weeks and days, the likely conception date and which trimester you are in.
Because every cycle is different, the due date is an estimate — most babies are born between 38 and 42 weeks. Use this calculator to plan scans, leave and your timeline, and always confirm the final date with your doctor or midwife.
