Pregnancy is one of the most exciting and life-changing journeys in a woman’s life. From the moment you discover that you are expecting, one of the first questions you ask is, “When will my baby arrive?” While no tool can predict the exact date of birth, a Pregnancy Due Date Calculator gives you a reliable estimate based on your last menstrual period (LMP) or conception date.

What is a Pregnancy Due Date Calculator?

A pregnancy due date calculator is a simple tool that helps expectant mothers estimate their baby’s arrival date. Doctors usually calculate the due date by adding 280 days (40 weeks) to the first day of your last menstrual cycle. However, since not all cycles are the same, using an online calculator is a quick way to get an approximate due date.

How Does It Work?

1. Enter the first day of your last menstrual period.
2. Select your average cycle length (usually 28 days).
3. The calculator then adds 280 days to provide your estimated due date.

This tool is especially helpful for women who want to track their pregnancy journey, prepare for prenatal check-ups, and plan ahead for their baby’s arrival.

Things to Keep in Mind

Remember, only about 4–5% of babies are born exactly on their due date. Most arrive within two weeks before or after. Your healthcare provider may also adjust the date based on ultrasound scans and your health conditions.

Using this calculator is a great first step to track your pregnancy timeline, but always consult your doctor for accurate medical advice.
