Free Gestational Age Calculator: Find Out How Far Along You Are in Pregnancy

How It Works:

Gestational Age Calculation: We calculate your gestational age by finding the difference in days between today's date and your LMP. The result is then converted into weeks and days for a clearer understanding of your pregnancy progress.

Estimated Due Date: Your EDD is calculated by adding 280 days (40 weeks) to your LMP. This is the average duration of a pregnancy, and knowing your due date helps you plan for your baby's arrival. Whether you're planning your prenatal visits or just curious about your pregnancy timeline, our easy-to-use calculator provides reliable information to help you stay informed.

FAQs for Gestational Age Calculator

What is gestational age?

Gestational age refers to the time elapsed since the first day of a woman's last menstrual period (LMP). It is used to estimate how far along a pregnancy is and helps track fetal development.

How is gestational age calculated?

Why is knowing gestational age important?

Can I use the gestational age calculator if I have irregular periods?

If you have irregular cycles, the calculator might not give the most accurate result. It’s advisable to consult your healthcare provider, who may use an early ultrasound for a more precise estimate.

What happens if my gestational age differs from ultrasound results?

Sometimes, your gestational age might differ slightly from ultrasound results. This could be due to the variation in fetal growth rates. In such cases, your healthcare provider will discuss which measurement to follow.

How accurate is a gestational age calculator?

A gestational age calculator provides an estimate based on the information you enter. While it’s a helpful tool, an ultrasound during early pregnancy offers a more accurate measurement of gestational age.
