Frequently Asked Questions
How does an age calculator calculate exact age in years, months, and days?
Enter the birth date and the date on which you want to calculate age. The result is normally expressed as completed years, months, and days.
Can an age calculator calculate age on a specific date?
It calculates the calendar difference between two dates rather than simply dividing the number of days by 365. That matters for month lengths and leap years.
How does an age calculator handle leap years and February 29 birthdays?
Yes. You can calculate age on a past or future date by using that date as the comparison date.
Is an age calculator accurate when the birth date is near the end of a month?
Leap years and February 29 are handled according to calendar-date rules. A Feb. 29 birthday can require a defined convention when the target year is not a leap year.
Can an age calculator calculate age in months, weeks, days, or total days?
Most calculators can also show the difference as total days or approximate weeks/months. These totals are useful, but months are calendar units and are not all the same length.
Why can two age calculators show slightly different results?
Different results usually come from different conventions for Feb. 29, time-of-day handling, inclusive/exclusive dates, or whether the tool uses UTC/local time.
