For women who are expecting their bundle of joy, the most anticipated day will be the arrival of their little one. It will be the day of labor and reward. Most of all, it will be the beginning of the growing family.

If you are eager to know when your due date is, the task is easier; you can even do it yourself. There are due date calculators that will help you assess when your baby might be due.

According to Recorder Journal, the calculator will give you an estimated date of birth that you can mark on your calendar. However, despite having an estimated date of birth, you should mind that only 3 to 5 percent of babies are born on their due date or "guess date."

Full-term pregnancy is classed between 37 to 42 completed weeks of pregnancy. The due date calculator will provide the estimated due date based on 40 weeks of pregnancy. This is the middle of the full term, which explains why only a few babies are actually born on the exact day.

If you want to try the due date calculator, you can access it here.

Before providing the calculated estimated due date, you have to provide the date of any of the following: conception date, due date by sonogram (reverse calculation), the first day of last menstrual period, date of 3-day embryo transfer or date of 5-day embryo transfer. The last two may apply to those who are trying to conceive via in-vitro fertilization (IVF).

Once the information is provided, it will give you the estimated due date, current gestational age, date of conception, first fetal heart tones by Doppler and end of the first trimester. Apart from this, it will also give the dates for the best time to evaluate cervical length in patients with risk factors and the best time for routine anatomy ultrasound and more.

Another due date calculator is available here. However, this one is simpler than the first one and has no options. It only asks for the first day of your last period and only provides the estimated due date. For those who are only after the day of their probable delivery date, this calculator will do.

Another way to find your estimated due date is by getting an ultrasound. A study suggested that adjusting a baby's estimated due date as a result of a first trimester dating ultrasound did not reduce the incidence of induced labor.

Another study in 2013 revealed that even if the date of ovulation was known, the length of pregnancy still varied by 37 days. The study excluded women who had the complications of preterm births.
