Welcome! Planning for a new arrival is exciting, and accurately predicting your due date is a vital first step. The expected birth calculator, also known as a pregnancy calculator, is a tool designed to estimate when your baby will arrive, marking the culmination of your pregnancy journey.

Calculate Your Due Date Now →How Does the Expected Birth Calculator Work?
Our Pregnancy Calculator & Ovulation Estimator offers several methods to pinpoint your expected due date, catering to different levels of information you might have about your pregnancy:
- Last Menstrual Period (LMP): This is the most common method. By entering the first day of your last period, the calculator estimates your due date by adding 280 days (40 weeks).
- Conception Date: If you know the exact date of conception, inputting it will provide a more precise due date estimate.
- IVF Transfer Date: For pregnancies achieved through In Vitro Fertilization (IVF), entering the transfer date of a 3-day or 5-day embryo provides an accurate due date calculation.
Understanding Your Results
The expected birth calculator not only gives you a due date but also provides insights into your current trimester and key pregnancy milestones. Remember that this is just an estimate; only around 4% of babies are born on their exact due date. Most babies arrive within a window of two weeks before or after this date.
Beyond the Due Date: Planning for Conception
Our tool doesn't just assist in tracking an existing pregnancy; it also helps in planning for conception. The Ovulation Estimator feature allows you to:
- Pinpoint Your Fertile Window: Based on your cycle length, the tool identifies the days you are most likely to conceive.
- Interactive Calendar: A color-coded calendar visually displays your period days, fertile window, and peak ovulation day, making planning easier.
Factors Affecting Your Due Date
While the expected birth calculator provides a helpful estimate, several factors can influence your actual delivery date:
- Cycle Length: Women with cycles longer or shorter than the average 28 days may have a slightly different gestational timeline.
- Ultrasound Measurements: Early ultrasounds can provide more accurate dating based on the baby's size.
- Individual Variations: Every pregnancy is unique, and babies come on their own schedule!
