Welcome to our Pregnancy Due Date Calculator!
This page is specially designed to help you estimate one of the most significant dates in your journey towards maternity: your baby’s due date.
Our calculator is a handy tool that can determine not only your expected date of delivery (EDD) but also give you an estimate of your conception date. To start, all you need is the date of your last menstrual period (LMP) and the length of your menstrual cycle.
Being pregnant is a thrilling, transformative time, and we understand the excitement that comes with tracking your baby’s development. Our calculator breaks down your pregnancy timeline into trimesters, helping you understand the different pregnancy stages and your pregnancy progress week by week.
Ever wondered how your baby bump will grow, when you might hear your baby’s heartbeat during an ultrasound, or when to schedule important doctor’s appointments? All these can be better planned when you know your gestational age and due date.
Our calculator helps you estimate which week of pregnancy you’re in. This information is essential for tracking your baby’s development and your growing baby bump. From the fluttering first movements in the second trimester to the powerful kicks in the third, each stage of pregnancy brings its unique joy and challenges.
Fertility and ovulation play significant roles in conception. Your fertile window—the days leading up to ovulation—represents the best time to try for a baby. Knowing your cycle length and the timing of your last menstrual period can help predict this window.
In addition, our calculator provides insights on full-term and preterm births. A full-term pregnancy is one that has reached at least 37 weeks but not exceeded 42 weeks. Deliveries before the 37th week are considered preterm, while those extending beyond 42 weeks are referred to as post-term.
While this pregnancy calculator does a great job of estimating your baby’s arrival, remember that only about 4% of babies are born precisely on their due dates. Hence, consider your due date as a rough estimate—a baby is typically born within a range of two weeks before or after the EDD.
Understanding pregnancy symptoms can be an essential part of your pregnancy journey. This tool can also help you prepare for the symptoms you might experience at each stage of your pregnancy.
Your journey through pregnancy is a unique and personal one. Use our Pregnancy Due Date Calculator as a guide through this exciting time as you anticipate the birth of your baby.

Questions and Answers
1. Q: How is the due date calculated?
A: The due date is typically calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP), assuming a 28-day menstrual cycle. This method is known as Naegele’s Rule.
2. Q: How accurate is a pregnancy due date calculator?
A: While a due date calculator provides a rough estimate of when your baby will arrive, remember that only about 4% of babies are born precisely on their due dates. Most babies are born within a range of two weeks before or after the estimated due date.
3. Q: What if I don’t know the first day of my last menstrual period or if my menstrual cycle is irregular?
A: If you can’t recall the first day of your last menstrual period or if your cycle is irregular, your healthcare provider might adjust your due date based on an ultrasound scan done early in pregnancy.
4. Q: Why is knowing my due date important?
A: Knowing your due date helps your healthcare provider monitor your pregnancy and baby’s growth accurately, schedule necessary prenatal tests, and determine whether your baby is overdue or not.
5. Q: Can the pregnancy due date calculator tell me the exact date of conception?
A: While the calculator can provide an estimate of your conception date based on your cycle length and LMP, it may not be 100% accurate as conception depends on various factors like the timing of ovulation and fertility.
6. Q: What is a full term, preterm, and post-term pregnancy?
A: A full-term pregnancy lasts from the 37th week to the 42nd week. A preterm or premature birth occurs before the start of the 37th week, while a post-term or prolonged pregnancy extends beyond 42 weeks.
7. Q: Can I use the pregnancy due date calculator to predict my baby’s birth date?
A: The calculator provides an estimated due date, but only a small percentage of babies are born exactly on that date. It’s more likely that your baby will arrive a few weeks before or after the estimated due date.
8. Q: Can I use the calculator to plan the best time for an ultrasound or maternity leave?
A: While the calculator can give you a rough timeline, it’s best to consult your healthcare provider to schedule ultrasounds or plan your maternity leave based on your specific circumstances and their medical advice.
