The pregnancy date is the exact date that the health care provider calculate an represents the date of the birth of your baby. This calculation is based on a variety of dates and information specific regarding your last period and average gestation time. The methods of calculating the pregnancy due date may vary from simple calendar to fancy electronics, or Chinese astrology, or software from the Internet.

Methods of calculating pregnancy due date:
-Naegle’s Rule – according to this method you establish the date of the first day of your last menstrual period, to count three months back from this date and add seven days. This will be the probable day of the birth.
-Basal Body Temperature and Luteinizing Hormone – through this method when a rise of  Basal Body Temperature and a surge in Luteinizing Hormone is a precisely ovulating time, if you take the date of the ovulation and add 266 days then you will have the accurately date of the birth.
-Conception Date – this is the most simple method to calculate the birth date, by adding 266 days to the date when you conceived the baby.
-Ultrasound – this is one of the many tests that woman do during the pregnancy. The ultrasound test use sound waves to create the picture of the baby. In the first pregnancy semester, the health care provider will determine through this test the age of the baby, therefore, the expected date of the birth.
-Last Menstrual Period – through this method the health care provider will ask you the first day of your last period, then he will add 14 days equivalent of the date of ovulation and conception. The date resulted will be added with 266 days, the average period that baby usually stays into the mother uterus, and the result will be the date of the birth.

The due date of the birth cannot be calculated precisely because the calculation is based on averages, less then 5% of the births happened in the due date calculated. The babies usually last between 38 and 42 weeks, practically 80% of the babies are born within 10 days of their due date, 10% of the women give birth before 38 weeks and 8% of the pregnant women deliver after 42 pregnancy weeks. Because every women is different the due date can be used only as a probable date.
