The Gestational Calculator is a practical online tool that allows you to quickly calculate your pregnancy timeline. By entering the first day of your last menstrual period (LMP), this tool provides an accurate estimated due date and your current gestational age in weeks and days. It is ideal for expecting parents, healthcare providers, and anyone monitoring pregnancy progress.

This tool removes the guesswork from pregnancy planning, making it easier to stay informed and organized throughout the nine-month journey.

How the Gestational Calculator Works

Pregnancy is typically calculated from the first day of the last menstrual period (LMP). A standard pregnancy lasts about 40 weeks (280 days). The Gestational Calculator uses this timeframe to determine:

  • Estimated Due Date (EDD): The expected delivery date based on LMP.
  • Current Gestational Age: The number of weeks and days that have passed since the LMP.

This calculation helps parents and healthcare providers understand where they are in the pregnancy and anticipate milestones, checkups, and necessary tests.
