What is a Pregnancy Due Date?

A pregnancy due date is an estimate of when a baby is expected to be born. It is typically calculated based on the first day of the last menstrual period (LMP) or the conception date. Understanding your due date can help you prepare for the arrival of your baby and track your pregnancy progress.

The average pregnancy lasts about 40 weeks, or 280 days, from the first day of the last menstrual period. This calculator helps you determine your estimated due date based on your LMP or cycle length.

Knowing your pregnancy due date can also assist you in making important prenatal care decisions and understanding when to attend regular check-ups. It’s crucial for parents to prepare not only for the joy of welcoming a newborn but also for the necessary lifestyle adjustments that come with parenthood.

How to Calculate Your Due Date

To calculate your due date, you can use the following formula:

Due Date = Last Menstrual Period + 280 days

Simply input your last menstrual period date and average cycle length into the calculator, and it will automatically compute your estimated due date.

Various online tools and mobile apps simplify this process, ensuring you stay informed throughout your pregnancy. Always consult with a healthcare provider to confirm your due date and to address any questions or concerns about your pregnancy.
