Enter your measurements to see your result.

Quick answer

Doctors track babies by weeks for the first months and by months after that. A baby born on 10 June 2026 is 16 weeks and 2 days old on 2 October 2026, or 3 months and 22 days. Vaccination schedules in India, such as those at 6, 10 and 14 weeks, use age in weeks, so this helps you plan visits.

How to measure

Enter your baby's date of birth.
Leave "on" blank for today, or pick a date.
Read the age in weeks, months and days.
