Cómo Funciona
How It Works
The Pregnancy Due Date Calculator estimates your baby’s expected arrival date based on the first day of your last menstrual period. It uses a standard pregnancy length of 280 days, which equals 40 weeks.
Once you enter the first day of your last period, the calculator simply adds 280 days to that date. This method is commonly used by healthcare providers to give a general due date estimate.
- Enter the first day of your last menstrual period
- The calculator adds 280 days (40 weeks)
- This is the average length of a full-term pregnancy
- The result is your estimated due date
Understanding the Results
The date shown is an estimated due date, not an exact prediction of when your baby will be born. Most babies arrive within a couple of weeks before or after this date.
Your actual delivery date can vary depending on your cycle length, ovulation timing, and individual pregnancy factors. Your healthcare provider may adjust the date based on ultrasound results or other medical information.
- It is an estimate, not a guaranteed birth date
- Full-term pregnancy ranges from 37 to 42 weeks
- Only a small percentage of babies are born on the exact due date
- Your doctor may adjust the date after early ultrasounds
