Due Date Calculator
Due Date Calculator
Planning for a new baby is one of the most exciting and life-changing journeys you’ll ever take. Knowing your baby’s expected arrival date helps you prepare for every step of pregnancy—from antenatal appointments and nutritional plans to shopping for baby essentials. Our due date calculator is a reliable and straightforward tool designed to help expectant mothers across the UK estimate their baby’s due date quickly and accurately.
Whether you conceived naturally or through assisted methods like IVF, this due date calculator works efficiently to provide you with a personalised timeline. It’s the perfect companion to help you track your pregnancy, especially if you’re seeking an alternative to the NHS due date calculator.
What is a Due Date?
A due date, also known as the estimated date of delivery (EDD), is the predicted calendar date when your baby is likely to be born. It is typically calculated based on the first day of your last menstrual period (LMP) or the date of conception. The average pregnancy lasts around 40 weeks from LMP, although delivery can occur a week or two earlier or later.
Our due date calculator offers a quick and convenient way to determine this important date, offering greater clarity and peace of mind as you progress through each trimester.
How Does Our Due Date Calculator Work?
Our easy-to-use due date calculator uses a medically recognised formula that aligns with current healthcare standards in the UK. Here’s how it functions:
LMP Method: If you know the first day of your last period, our tool calculates your estimated due date by adding 280 days (40 weeks) to that date.
Conception Date Method: If you’re sure about your conception date, the calculator adds 266 days to it to find your EDD.
IVF Method: If your pregnancy is the result of IVF, our due date calculator after IVF lets you enter the embryo transfer date to calculate your baby’s estimated arrival.
The calculator is custom-built for women across the UK, whether they’re exploring options outside the NHS due date calculator or looking for IVF-specific calculations.

Understanding Pregnancy Trimesters Using the Due Date Calculator
Once you’ve received your estimated due date, the next step is understanding your trimester timeline:
First Trimester (Week 1–12): Early pregnancy symptoms, first scans, and booking appointments with your midwife.
Second Trimester (Week 13–26): Feeling the baby’s first movements and routine anomaly scans.
Third Trimester (Week 27–40): Final preparations, hospital bag checklists, and monitoring labour signs.
Using our due date calculator, you can plan each phase with confidence.
IVF Pregnancies and the Due Date Calculator After IVF
IVF pregnancies follow a slightly different timeline. With IVF, your embryo transfer date is a more accurate point of reference than your LMP. Our due date calculator after IVF uses this information to give you a more precise EDD.
Here’s how:
Day 3 Embryo Transfer: Add 263 days.
Day 5 Embryo Transfer: Add 261 days.
This is where our tool offers a distinct advantage over the NHS due date calculator, which may not support IVF-specific entries. By using the due date calculator after IVF, you gain better accuracy tailored to your unique pregnancy journey.

Our tool is built on evidence-based formulas used by professionals in the UK healthcare system. Whether you’re double-checking the results from the NHS due date calculator or starting fresh, you can count on our calculator to provide consistency and trustworthiness.
