Age in Months Calculator
Find an exact age in months and days from a birth date.
Age counted in months
For babies and toddlers, age is measured in months, not years, and working out the exact figure by hand is fiddly around month boundaries. This calculator gives the precise months and days.
It counts complete calendar months from the birth date to today, then the remaining days, and also reports the totals. It is ideal for tracking a child’s milestones.
Precise and private
The calculation runs in your browser, so the birth date is never uploaded.
