PREGNANCY CALCULATORS
The estimated due date is the date that spontaneous onset of labour is expected to occur which can be checked using a pregnancy calculator. Pregnancy usually lasts from 37 to 42 weeks from day one of your last period.
It is normal for expectant mothers to be curious about their estimated date of delivery (EDD), which is also called the due date. If you are eager to know when your little bundle of joy will come into this world, our easy-to-use pregnancy due date calculator will do the work for you.

Finding out that you are pregnant brings a flood of emotions — excitement, apprehension, confusion and elation all at once. If you have taken a pregnancy test because you missed your period and found out that it was positive or if you consulted your doctor for the same, the next step would be to know how far along you are in terms of total weeks of pregnancy.
Before we go on, here’s some interesting information. A human egg can fertilize for only 12 to 24 hours after ovulation, so the date of ovulation usually is a reasonably good indicator to estimate the date of conception. Ultrasound, another way to determine the date of ovulation suggests only the gestational age, and hence is not considered perfect. In fact, an accurate date of conception is usually arrived at only in the case of IVF (In Vitro Fertilization).
Determining the Estimated Due Date
Estimated Due Date (EDD or EDC) is the date on which a non-induced delivery is expected to occur. You can calculate the approximate date by considering the first day of the Last Menstrual Period (LMP) and adding 280 days to this. With the pregnancy due date calculator, you will also be able to calculate the number of weeks and days you are into your pregnancy.
The accuracy of the estimation of EDD in this method depends on how accurately the mother can recall the day of intercourse, if she has regular 28-day cycles and ovulation, and conception occurs on the 14th day of the cycle. Assumption of LMP to arrive at the due date of pregnancy may result in an overestimation of the pregnancy duration to the tune of over 2 weeks.
Coming to ultrasound, this approach considers the size of the foetus to determine the gestational age (the time since the first day of LMP). The accuracy of such an estimate of the gestational age varies. Using ultrasound to measure the foetus in the first trimester (up to and including 13 6/7 weeks of gestation) is the most accurate method to arrive at the gestational age.
In the case of Vitro Fertilization (IVF), the date of conception will be known accurately, and EDD can be calculated by adding 266 days to that date.
As you progress into your pregnancy, your baby grows every day and your body changes too. You can use the week-by-week pregnancy calculator to better assess the trimester of your pregnancy, developments and experiences you have and can expect to have. Happy pregnancy!

The pregnancy due date calculator is used by working out the first day of your last period and approximately how many days your menstrual cycle lasts (the average cycle is 28 days). The tool will calculate 40 weeks from the first day of your last menstrual period.
Your due date is calculated from the end of your last period plus 40 weeks or 280 days. It is highly likely though, that your baby will not arrive on the exact due date, but a couple of weeks on either side of it.
Most pregnancies go on for about 40 weeks, so the best way to estimate your date of conception is to figure out when your last menstruation period was and then count 40 weeks or 280 days from that date.
The period of pregnancy usually lasts between 38 and 42 weeks. It can be tricky to calculate how far you are along in the pregnancy because your baby is 2 weeks younger than the pregnancy start date. This is referred to as ‘gestational age’.
The pregnancy due date calculator works by calculating the first day of your last period and approximately how many days your menstrual cycle is (the average cycle is 28 days). The tool will then calculate 40 weeks from the first day of your last menstrual period.
Enter your first day of your last period into the pregnancy week calculator and hit the submit button.
Note* Every pregnancy is unique therefore the result will be an estimation date than a fixed date.
To calculate your pregnancy weeks, just count from the first day of your last period to the current date in weeks. That way you will get how many weeks of pregnancy is over.
- Add 280 days (40 weeks) to the first day of your last menstrual period (assuming a 28-day cycle).
- Your menstrual period and ovulation are counted as the first two weeks of pregnancy. This is why a pregnancy ovulation calculator is helpful to pinpoint the exact ovulation cycle.
- If you deliver on your due date, your baby is actually only 38 weeks old, not 40.
This date is just an estimate, only about 4% of babies are born on their due date. This device can only give you an approximate date of baby’s arrival.
The estimated date of delivery is the date on which you are most likely to deliver your baby. It is commonly known as the pregnancy due date. The measurement of how many weeks far along you are in your pregnancy in weeks is called the gestational period. It is important for both you and your obstetrician to know your gestational age as it helps in providing the right care for mother and foetus at every stage of your pregnancy.
However, due date is only an estimation of when you will give birth and it does not mean that your baby will be born exactly on that date. Considering that usually a pregnancy can last anywhere between 37 and 42 weeks, and that the date of delivery depends on a variety of factors, your baby may be born a few days earlier or later than the estimated due date.
A full term pregnancy lasts for about 40 weeks or 280 days. The due date is usually calculated in a number of ways, such as:
1. The first day of your last period: Knowing the first day of your last menstrual cycle is helpful in arriving at your estimated date of delivery and to calculate your pregnancy weeks. Due date can be calculated by adding 280 days to the first day of your last period. This is based on a 28-day menstrual cycle. You can also use the Naegele’s rule to calculate due date. In this method, you add seven days to the first day of your last cycle and subtract three months. Counting one year ahead of that date will help you arrive at your estimated delivery date.
2. Prenatal ultrasound: If you are not sure of the date of your last menstrual period, an ultrasound will give a more accurate estimate of when your baby will be born. Your obstetrician may advise an early pregnancy ultrasound (usually done at 12 weeks), which will measure the length of the foetus from the crown to the rump. This will help your healthcare provider to arrive at a date.
3. Use the due date calculator: This is easiest way for you to estimate your total weeks of pregnancy and when your little one is expected to enter the world. All you have to do is enter the first day of your last period, and our calculator will tell you the due date. The calculator is based on a 28-day menstrual cycle.
