How To Use
Due Date Calculator?

Our Due Date Calculator is simple, fast, and requires no effort.
To find your estimated due date, just enter:

• The first day of your last menstrual period (LMP)
• Your average cycle length

The calculator then estimates your baby’s arrival date based on a standard 40-week pregnancy cycle.

💡 Tip: If you’re not sure about your cycle length, don’t worry — the calculator uses the default average of 28 days to give you an accurate estimate.

How do you calculate the
due date from conception?

If you know your conception date, the calculator can also estimate your due date by adding 38 weeks to that date.

This method assumes a typical pregnancy length and covers all three trimesters from the date of conception. It’s a helpful way to understand your pregnancy timeline, especially if you conceived through fertility tracking or assisted reproduction methods.

What is an estimated
due date (EDD)?

Your Estimated Due Date (EDD) is the most likely day your baby will be born, calculated using your LMP or date of conception.

However, it’s important to remember that every pregnancy is unique — and your actual delivery date may vary depending on:

• Your baby’s growth and position.
• The type of pregnancy (normal or high-risk).
• The planned mode of delivery (natural birth or C-section).

In fact, studies show that only about 4% of babies are born exactly on their due date! Most arrive within a week before or after the estimated day — perfectly normal and healthy.
