A pregnancy due date calculator estimates your delivery date using Naegele’s rule: 280 days (40 weeks) from the first day of your last menstrual period (LMP). It adjusts for cycle lengths other than 28 days, and also shows the estimated conception date and how many weeks along you are today. Only about 5% of babies arrive on the exact date.
Because ovulation drives conception, the tool corrects for cycle length. A 32-day cycle is 4 days longer than the standard 28, so it adds those 4 days: the due date becomes LMP + 284 days and the estimated conception moves to about day 18 instead of day 14. It then counts from your LMP to today to show how many weeks and days pregnant you are and which trimester you are in.
Use it early in pregnancy for a working timeline of milestones — the end of the first trimester at week 13, the anatomy scan around week 20, and full term from week 37. The due date is only an estimate: a normal birth can happen anywhere from 37 to 42 weeks, and an early dating ultrasound is more precise. This tool is for information, not medical advice; your provider confirms your dates.
