Pregnancy Due Date Calculator

The due date and stage of the pregnancy are probably the two most common questions asked by pregnant woman when they first find out about their condition. In fact, every plan and move during a woman’s pregnancy revolves around the due date.

The Calculator

The pregnancy due date calculator is a simple mathematical tool designed to estimate your due date and gestational week. You simply enter the date of the first day of your last menstrual period and the average duration of your period. The tool will compute an approximate due date and your present gestational week within seconds.

The pregnancy due date calculator is available online for free. Many websites offer it. You should, however, remember that this date is not calculated from the actual date of conception. In fact, it is virtually impossible to predict that date since ovulation lasts for a period of two to three days. Most doctors and the pregnancy due date calculator compute the due date by counting 40 weeks from the first day of your last menstrual period.


The obvious advantage of a pregnancy due date calculator is that it allows you to plan your pregnancy. You can plan your work accordingly, and keep everything ready for the new baby. It will also help your doctor plan your diagnostic tests such as blood sugar test and ultrasound evaluation.

Many websites offer week-by-week development charts about pregnancy and baby’s development. So, if you know your due date and stage, you can track the progress of your baby. You can also compare your symptoms with those of other women, and alert your doctor immediately if you notice something abnormal.


While the pregnancy due date calculator is a very popular tool among pregnant women nowadays, only fewer than five per cent of babies actually arrive on their due date. The calculator also does not work for women who have irregular menstrual cycles, or those who are not sure of their first day of the last menstrual cycle. Ultrasound is considered to be more accurate.

Healthy Pregnancy

Although many women obsess about their due date and spend a lot of time on the pregnancy due date calculator, it is important to focus factors that will help you have a successful pregnancy:

  • Eat a healthy and balanced diet. Avoid alcohol and caffeine. Drink plenty of fluids, along with lots of fruits and vegetable.
  • Sleep for at least eight hours at night. Adequate rest will relieve stress and help you and your baby.
  • Dress in comfortable clothes.
  • Exercise regularly. Walking, swimming and yoga are completely safe during pregnancy. Talk to your doctor if you have any concerns.
  • Stay close to friends and family. They will make your pregnancy enjoyable and stress-free.
  • Listen to your body and enjoy its changes throughout these amazing months. Talk to your doctor if you have any concerns.
