Our comprehensive pregnancy calculator due date gestational age in weeks & months is designed to provide accurate pregnancy calculations for expecting mothers. This free online tool calculates your due date, current gestational age in weeks and gestational age in months, helping you track your pregnancy journey with precision.

How to Calculate Due Date and Gestational Age

Our pregnancy calculator offers multiple calculation methods to determine your due date and gestational age:

• Last Menstrual Period (LMP): Most common method - adds 280 days (40 weeks) to your last period
• Conception Date: If you know when conception occurred, adds 266 days for accurate due date
• Ultrasound Dating: Uses ultrasound measurements to calculate gestational age and due date
• IVF Transfer Date: For IVF pregnancies, calculates based on embryo transfer date and embryo age
• Known Due Date: Calculate current gestational age if you already know your due date

Understanding Gestational Age in Weeks & Months

Gestational age is measured from the first day of your last menstrual period, not from conception. Our calculator displays both:

• Gestational age in weeks: Shows exact weeks and days (e.g., 22 weeks, 3 days)
• Gestational age in months: Converts to months format (e.g., 5 months, 2 weeks, 3 days)
