Age Calculator: Calculate Your Exact Age From Your Date of Birth

Age Calculator CTL is a free online age calculator designed to help you calculate how old you are on a specific date. Instead of simply subtracting one year from another, the calculator considers the calendar relationship between a birth date and the date you want to measure.

What Is an Age Calculator?

An age calculator is a date-based tool that determines a person's chronological age. A modern online age calculator can also show age in years, months, days, weeks, hours, minutes and seconds.

How Is Age Calculated?

Age is commonly expressed by completed years, followed by the remaining months and days since the person's last birthday. The calculation needs to account for leap years and the different number of days in each month. This is particularly important around month-end dates and February.

Can I Calculate My Age on a Specific Date?

Yes. The date of birth calculator lets you choose the exact date on which you want to calculate your age. This can be useful for historical checks, future birthdays, event planning and date-based records.

How Accurate Is an Age Calculator?

Accuracy depends on the dates you provide and the calendar rules used by the calculator. Age Calculator CTL uses calendar-aware date arithmetic for years, months and days and calculates totals from the exact date interval.

Age in Days, Weeks, Hours, Minutes and Seconds

In addition to a traditional age such as “30 years, 4 months and 2 days,” you can view the interval as total days, weeks, hours, minutes and seconds. These totals are useful for understanding the same date interval in different units.
