ABOUT THIS TOOL
What is the Age Calculator?
An age calculator measures elapsed calendar time from a birth date to today. It accounts for different month lengths and displays years, months, days and total days.
How the result is calculated
The tool subtracts calendar components rather than simply dividing milliseconds by 365 days, so birthdays and variable-length months are handled correctly.
Practical example
Someone born on January 1, 1988 is 38 years old during most of 2026, with the exact months and days depending on today’s date.
