Pregnancy Due Date Calculator

The Pregnancy Due Date (or estimated delivery date, EDD) is the estimated date when a pregnant person is expected to give birth. This date is typically calculated based on the first day of the last menstrual period (LMP) or by using an ultrasound to measure the gestational age of the fetus.

How to Calculate Due Date

The most common method to calculate the due date is the Naegele's Rule, which is as follows:

1. Identify the first day of your last menstrual period (LMP).
2. Add one year to the year of the LMP.
3. Subtract three months from the month of the LMP.
4. Add seven days to the day of the LMP.

Alternatively, you can use an online calculator, which will provide a quick estimate based on your inputs.

Understanding the Result

The due date is an estimate; only about 5% of babies are born on their exact due date. The due date can help parents:

• Prepare for the arrival of the baby.
• Schedule necessary prenatal appointments.
• Plan for parental leave from work.

Improving Health During Pregnancy

Regardless of the due date, maintaining good health during pregnancy is vital. Here are some tips:

• Regular Prenatal Care: Attend all scheduled appointments with your healthcare provider.
• Healthy Diet: Focus on a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and dairy.
• Exercise: Engage in safe physical activity as recommended by your doctor.
• Stay Hydrated: Drink plenty of water.
• Avoid Harmful Substances: Stay away from alcohol, tobacco, and certain medications.

This calculator provides an easy way for users to estimate their pregnancy due date based on the last menstrual period.

Note: It’s essential to consult a healthcare provider for personalized prenatal care and to confirm the due date.
