How the Due Date Estimate Works

A common pregnancy dating method starts with the first day of the last menstrual period and estimates about 40 weeks of pregnancy. This calculator also adjusts the estimate when the selected menstrual cycle length differs from 28 days.

Remember: An estimated due date is a reference date, not a guarantee of the exact day labor will begin.

First Trimester

The first trimester covers the early stage of pregnancy. Prenatal care and accurate pregnancy dating are especially useful during this period.

Second & Third Trimesters

Pregnancy progress is usually followed in weeks. Your clinician may use ultrasound and other clinical information when confirming or revising dating.

Important Medical Note

This calculator is for general educational use only and does not provide medical diagnosis or individual medical advice. Menstrual dates can be uncertain, cycles vary, and ultrasound findings may change pregnancy dating. For prenatal care, symptoms, pregnancy concerns, or confirmation of your due date, consult a qualified healthcare professional.
Cycle Length

What does average cycle length mean?

Cycle length is counted from the first day of one menstrual period to the first day of the next. A 28-day cycle is commonly used as the standard reference in due-date calculations.

1

Start Day

First day of your menstrual bleeding.

2

Next Period

Count until the first day of the next cycle.

3

Average

Use your usual cycle length if known.
