Due Date Calculator | Easy Way to Estimate Your Expected Delivery Date Accurately

Introduction

Calculating the due date is one of the most important concerns for pregnant women who want to know when they will meet their baby.

In this article, we will explain simple and accurate methods to estimate your due date without confusion.


What Is the Expected Due Date?

The expected due date is the approximate date when the baby is expected to be born, calculated based on the last menstrual period or ultrasound results.


How Is the Due Date Calculated?

The due date is usually calculated by adding 280 days (40 weeks) to the first day of the last menstrual period.


Calculating Due Date from Last Menstrual Period

  • First day of the last period = starting point
  • Add 7 days
  • Subtract 3 months
  • Add 1 year

This is the most commonly used method by doctors.


Factors That Affect the Due Date

  • Length of menstrual cycle
  • Timing of ovulation
  • Baby’s growth and condition
  • First pregnancy or previous pregnancies

Is the Due Date 100% Accurate?

No, the due date is only an estimated date. Most babies are born a few days or even weeks before or after it.


Signs of Approaching Labor

  • Baby drops lower into the abdomen
  • Stronger uterine contractions
  • Discharge or water breaking
  • Lower back pain
