How Baby Age is Calculated

The calculation is based on the difference between the current date and the conception date. The result is presented in weeks, months, and days.

Baby Age (Days) = Current Date - Conception Date Baby Age (Weeks) = Baby Age (Days) / 7 Baby Age (Months) = Baby Age (Days) / 30.44 (average days in a month)

Note: This calculation assumes a standard 40-week pregnancy. Actual fetal development may vary.

Example Calculation

If conception occurred on January 1, 2023, and today is April 1, 2023:

Total days: 91
Weeks: 13 (13 weeks and 0 days)
Months: 3.0 (approximately 3 months)

At 13 weeks, the baby is about the size of a lime and has developed fingers, toes, and facial features.
