How it works
Compare the calendar dates to find complete years, then the remaining months and days. The result updates when you change the as-of date.
Worked example
A birthday of January 1, 1995 gives a different age on December 31, 2025 than on January 1, 2026.
Keep in mind
The result uses calendar dates and does not depend on birth time or time zone.
