The pregnancy due date calculator estimates when the baby is expected to arrive. Whether you're excited, nervous, or just curious, this page will help you understand where you might be in your pregnancy journey. However, the tool provides a helpful general estimate; the actual due date may shift as your cycle is longer or shorter than 28 days.

How to Calculate Your Pregnancy Due Date

You just need to know the last date of your previous monthly cycle and calculate your gestational age and the baby’s arrival date. In case of IVF, you need to know the transfer date and embryo age to calculate the estimated due date.

The pregnancy calculator uses the EDD formula to estimate the gestational age.

EDD Formula (for non-28-day cycles): If your cycle is longer than 28 days (e.g., 31 days), ovulation likely occurred later, so your estimated due date will shift accordingly.

EDD = LMP + [280 + (Cycle Length – 28)] days

IVF Pregnancy Due Date Calculator

The IVF pregnancy due date calculator is for women who conceive through IVF (in vitro fertilisation). The IVF transfer date is known with certainty, and the due date is calculated using the embryo transfer date. IVF pregnancy calculators offer a more precise starting point since embryo transfer dates are known. However, delivery timelines may still vary, just like natural pregnancies.

Day 3 embryo transfer

If your transfer was on day three, you can calculate your pregnancy due date by adding 263 days from the transfer date.

Day 5 embryo transfer

If your transfer was on day five, your due date is calculated by adding 261 days.

Day 6 embryo transfer

If your embryo transfer took place on day six, your pregnancy due date is typically calculated by adding 260 days to the transfer date.

How Accurate is an Online Pregnancy Calculator?

Our pregnancy calculator is based on medical standards used by healthcare providers worldwide. It works by using:

  • The first day of your Last Menstrual Period is a clinically accepted method to estimate pregnancy duration and due date.
  • A standard pregnancy length of 280 days (40 weeks) from LMP*.
  • IVF users factor in the embryo transfer date and embryo age according to the fertility clinic guidelines.
Research shows that only 4-5% of babies are born on their estimated due date. Mostly, labours occur within a 37-42 week window. So, a pregnancy date calculator is a helpful tool, but not a guarantee.

Not Pregnant Yet? Here’s Why This Tool Still Matters

Trying to conceive? An ovulation calculator helps track your fertile days based on your cycle, giving you a better chance to plan pregnancy naturally.

  • Learn what to expect in each trimester ahead of time.
  • Understand how due dates are calculated.
  • Know what costs you’ll face and how to cover them.

Why Insurance Timing Matters

Most maternity insurance plans won’t offer coverage once you're pregnant due to the waiting period. Buy maternity insurance in time (before pregnancy) so you’re fully protected when the journey begins. We cover pre- and post-hospitalisation, maternity benefit, prenatal checkups, NICU (Neonatal ICU), delivery expenses, and much more. Secure your baby before you conceive.

Know your baby’s arrival date and prepare for parenthood in advance!

FAQs About Pregnancy Calculator

Q. How does a pregnancy calculator estimate my due date?

Answer: A pregnancy calculator estimates your due date by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). If you know your ovulation or conception date, it can offer a more accurate result.

Q. How many weeks pregnant am I?

Answer: You can calculate how many weeks pregnant you are by entering your last period or conception date into a pregnancy calculator. It shows your current week, trimester, and time left until your due date.

Q. Can I use a pregnancy calculator with irregular periods?

Answer: Yes, but the results may not be precise. If your cycle is irregular, use a calculator that allows cycle length adjustments, or confirm your due date with an early ultrasound.

Q. What week of pregnancy am I in?

Answer: You are in a specific pregnancy week based on the number of weeks since your LMP or conception. A pregnancy calculator instantly tells you your current week and trimester.

Q. Will my due date change?

It’s possible if an early ultrasound shows that your baby is measuring significantly ahead or behind the expected size per LMP. However, in most cases, your original due date stays the same. Keep in mind that it’s always an estimate, not an exact prediction.
