Introduction
Knowing your estimated due date is one of the most exciting and important milestones in pregnancy. While every pregnancy is unique, a due date helps you plan appointments, prepare your home, and get ready for your little one’s arrival.
With the Pregnancy Due Date Calculator, you can quickly estimate your baby’s arrival based on your last menstrual period (LMP) or conception date.
How a Pregnancy Due Date Is Calculated
Pregnancy is typically about 40 weeks (280 days) long, starting from the first day of your last menstrual period.
There are a few methods to estimate your due date:
-
Using Last Menstrual Period (LMP): The most common method; assumes a 28-day cycle.
-
Conception Date: If you know the exact date of ovulation or conception.
-
Ultrasound Measurement: Especially helpful if your cycle is irregular or you’re unsure of your LMP.
Formula (Naegele’s Rule):
-
Add 1 year to the first day of your last menstrual period.
-
Subtract 3 months.
-
Add 7 days.
Example:
-
LMP: January 10, 2025
-
+1 year → January 10, 2026
-
-3 months → October 10, 2025
-
+7 days → October 17, 2025 (estimated due date)
