Estimated Due Date Calculator

This Due Date Calculator provides an estimated delivery date for your baby. By entering the first day of your last menstrual period (LMP), the tool calculates your due date based on a 40-week pregnancy. This provides a simple and reliable estimate to help you plan for your baby’s arrival and schedule prenatal care. The calculation is based on the standard method used by healthcare providers.

LMP-Based Calculation: The calculator uses the first day of your last menstrual period to estimate your due date, which is the most common calculation method.

• Simple Interface: Requires only one piece of information—the date—to generate a result.
