Due Date Calculator

How is Due Date Calculated?

The due date is the estimated date when your baby will be born. If you know your conception date, this calculator estimates your due date by adding 266 days (38 weeks) to it.

Due Date Formula

Due Date = Conception Date + 266 days (38 weeks)

Example Calculation

If conception occurred on January 15, 2024:

Conception Date = Jan 15, 2024
Due Date = Jan 15, 2024 + 266 days = October 8, 2024
