The Pregnancy Week Calculator estimates how many weeks pregnant you are based on your due date and the current date. It helps track pregnancy progress and anticipate important milestones.
The calculator uses the following calculation:
Where:
Explanation: The calculator determines the time difference between the current date and due date, then converts days to weeks.
Details: Tracking pregnancy weeks helps monitor fetal development, schedule prenatal tests at appropriate times, and prepare for delivery.
Tips: Enter your due date (typically provided by your healthcare provider) and the current date (defaults to today). The calculator will show how many weeks pregnant you are and how many weeks remain until your due date.
Q1: How accurate is this calculator?
A: The accuracy depends on the accuracy of your due date. Ultrasound-determined due dates are typically most accurate.
Q2: What if my due date has passed?
A: The calculator will show how many weeks and days have passed since your due date.
Q3: Why count pregnancy in weeks?
A: Pregnancy changes happen rapidly, and week-by-week tracking provides more precise monitoring than month-by-month.
Q4: What's considered full term?
A: 39-40 weeks is considered full term. Babies born between 37-38 weeks are early term, and after 41 weeks is late term.
Q5: Can I use this for IVF pregnancies?
A: Yes, but your due date calculation for IVF may be different - consult your fertility specialist for the most accurate due date.
