Gestation Weeks Calculation:
From: | To: |
The Weeks Gestation Calculator estimates how many weeks pregnant a woman is based on her due date and the current date. This helps track pregnancy progress and ensure proper prenatal care timing.
The calculator uses the following formula:
Where:
Explanation: The calculation determines the difference in days between two dates and converts it to weeks.
Details: Accurate gestation week calculation is crucial for monitoring fetal development, scheduling prenatal tests, and determining the appropriate timing for interventions.
Tips: Enter the due date and current date (defaults to today). The calculator will show weeks of gestation or how many weeks overdue if the due date has passed.
Q1: How accurate is this calculation?
A: This provides an estimate based on dates. Ultrasound measurements in early pregnancy provide more accurate dating.
Q2: What if my due date changes?
A: Recalculate using your new due date. Due dates are often adjusted after ultrasound examinations.
Q3: Why does it show negative weeks?
A: Negative values mean the current date is past the due date, indicating the pregnancy is overdue.
Q4: How is this different from conception date calculation?
A: This calculates from due date (typically 40 weeks from LMP), while conception date would be about 38 weeks before due date.
Q5: Can I use this for multiple pregnancies?
A: Yes, though multiples often deliver earlier than the calculated due date.
