What is EDD (Estimated Due Date)?
Estimated Due Date (EDD) is the approximate date calculated by your healthcare provider to predict when your baby is most likely to be born. This date is usually calculated based on your Last Menstrual Period (LMP) and the average length of your menstrual cycle.
How does the pregnancy due date calculator work?
To use our accurate due date calculator, enter all the required details. Your LMP or last menstrual period and the length of your cycle to accurately predict your estimated due date.
LMP or last menstrual period is used to calculate the baby’s estimated due date. Ideally, healthcare experts and pregnancy calculators estimate the due date by calculating 280 days or 40 weeks from the first day of your last menstrual period.
The length of your cycle is important to maintain accuracy in predicting the baby’s due date. Say if Jan 1st 2025 was the first day of your last period, then your ideal due date would be 280 days or 40 weeks from January 1st, that is, October 10, 2025.
Important factor to keep in mind
Although healthcare experts provide an estimated due date or EDD for all mothers, not all babies are born on that exact date.
Studies say that only about 4 out of 100 babies are born on that exact date. In some cases, your gynecologist might also alter the EDD according to the baby’s growth and development.
