Estimated Due Date (EDD)
The LMP EDD Calculator is a simple yet powerful tool that estimates your baby’s due date based on the first day of your last menstrual period (LMP).

By entering your LMP date, you can instantly see the projected delivery date, helping you make informed decisions throughout your pregnancy.

- Pregnancy Duration: Standardized at 280 days from the LMP.
- Calculation Method: Adds 280 days to the LMP to estimate delivery.
By leveraging this calculation, the tool provides a reliable EDD that aligns closely with medical estimates used in obstetrics.
