## About Pregnancy Due Date Calculator

A pregnancy due date calculator is a tool that can help expectant mothers determine when they can expect to give birth. The calculator typically requires one piece of information as input: the date of the woman's last menstrual period.

Based on this information, the calculator can estimate the due date of the pregnancy, which is the expected date of delivery. The due date is typically calculated as 40 weeks (or 280 days) from the first day of the woman's last menstrual period. However, it is important to note that due dates can vary from person to person, and only about 5% of women give birth on their actual due date.

It's important to note that due date calculation is a rough estimate based on average menstrual cycles, it's not 100% accurate for every individual. The due date is an estimation and the actual day of birth might be before or after the due date. A healthcare professional, like an Obstetrician, will likely confirm the due date during the first prenatal visit and with the help of ultrasound.
