Baby Birth Date Calculator

Pregnancy is one of the most exciting journeys in life. One of the first questions expectant parents ask is:
“When will my baby be born?”

The Baby Birth Date Calculator helps you estimate your due date based on your last menstrual period (LMP), conception date, or even the date of IVF transfer. While only about 5% of babies are born on their exact due date, this tool provides a reliable timeframe so you can plan ahead for your little one’s arrival.

Whether you’re newly pregnant or planning for conception, this calculator is a simple, stress-free way to track your baby’s expected birth date.

How to Use the Baby Birth Date Calculator

1. Enter the first day of your last period – The most common way to calculate due date.
2. Input your average cycle length – Usually 28 days, but you can adjust if yours is different.
3. Click Calculate – The tool instantly shows your estimated due date.
4. (Optional) If you know your conception date or had an IVF procedure, you can use those dates for even more accuracy.
