How it works
The tool compares your birth date with today. Years are counted first, then remaining whole months, then days — borrowing from the previous month when the day-of-month of the birth date exceeds today's, exactly as ages are conventionally counted.
Frequently asked questions
How is age in months and days calculated?
After counting whole years, the remaining whole months are counted, then the leftover days. This mirrors how birthdays and anniversaries work in everyday life.
Can I calculate age on a specific date?
Yes — set the 'as of' date to any day to see how old someone was or will be on that date.
