Pampers Due Date Calculation:
From: | To: |
The Pampers Due Date Calculator estimates your baby's birth date by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). This is based on the standard method for calculating pregnancy due dates.
The calculator uses the simple formula:
Where:
Explanation: This calculation assumes a regular 28-day menstrual cycle with ovulation occurring on day 14. Only about 5% of women deliver on their exact due date.
Details: Knowing your estimated due date helps healthcare providers monitor fetal development, schedule important prenatal tests, and determine if the pregnancy is progressing normally.
Tips: Enter the first day of your last menstrual period in the format YYYY-MM-DD. The calculator will add 280 days (40 weeks) to this date to estimate your due date.
Q1: How accurate is this due date calculation?
A: It's a standard estimation, but only about 5% of women deliver on their exact due date. Most deliver within 2 weeks before or after.
Q2: What if my cycles aren't 28 days?
A: This calculation works best for women with regular 28-day cycles. If your cycles are longer or irregular, an ultrasound may provide a more accurate due date.
Q3: Why 280 days/40 weeks?
A: Pregnancy is traditionally calculated as 40 weeks from LMP, though actual gestation from conception is about 38 weeks.
Q4: When will my healthcare provider adjust my due date?
A: Providers may adjust based on early ultrasound measurements, especially if they differ significantly from LMP-based calculation.
Q5: What's the difference between gestational age and fetal age?
A: Gestational age is measured from LMP, while fetal age is from conception (about 2 weeks less).
