Pregnancy Due Date Calculator

The Pregnancy Due Date Calculator is a tool that helps expectant mothers and their partners estimate the due date of their baby based on the mother’s last menstrual period and cycle length. The estimated due date can be useful for planning prenatal care and preparing for the baby’s arrival.


To use the Pregnancy Due Date Calculator, follow these steps:

  1. Open the Pregnancy Due Date Calculator in your web browser.
  2. Enter the date of the mother’s last menstrual period in the “Last Period Date” field. This date is usually the first day of the mother’s last period.
  3. Select the mother’s cycle length from the “Cycle Length” drop-down menu. If the mother is unsure of her cycle length, she can select “I Don’t Know” from the drop-down menu. The default cycle length is 28 days.
  4. Click the “Calculate” button to calculate the estimated due date. The estimated due date is based on a pregnancy lasting for 280 days (40 weeks) from the first day of the mother’s last menstrual period.
  5. The estimated due date will be displayed in the “Due Date” field in the format MM/DD/YYYY.

It’s important to note that the Pregnancy Due Date Calculator is an estimate only and should not be used as a definitive indicator of the baby’s due date. It’s always best to consult with a healthcare provider for an accurate due date estimate and for individualized prenatal care.

In conclusion, the Pregnancy Due Date Calculator is a helpful tool for expectant mothers and their partners to estimate the due date of their baby based on the mother’s last menstrual period and cycle length. By following the simple steps outlined above, you can quickly and easily calculate the estimated due date and begin planning for the arrival of your baby.
