Age Calculator
Find your exact age in years, months, and days with our free online Age Calculator. You can also check your age on any past or future date.
What is an Age Calculator?
An Age Calculator is an online tool that calculates a person's exact age based on their date of birth and a selected date. Instead of simply subtracting one year from another, it calculates the difference in years, months, and days.
The DigitalMind Tools Age Calculator can also show the total number of days, weeks, months, and hours between two dates. You can use it to check your current age or find out how old you were, or will be, on a specific date.
How to use our free online Age Calculator
Using the Age Calculator is simple. Enter your date of birth, choose the date you want to calculate your age as of, and let the tool do the rest.
- Select your date of birth in the date of birth field.
- Check the date in the calculate age as of field. It defaults to today's date, but you can choose a different past or future date.
- Click calculate my age.
- Review your age in years, months, and days, along with the additional date information shown below the result.
The calculation takes month lengths and leap years into account, so the result is based on the actual dates you enter.
Why use an Age Calculator?
Calculating an exact age can be useful when you need more than the number of years between two dates. An Age Calculator can help you check your age for forms, applications, school records, birthdays, anniversaries, or personal milestones.
It can also be useful when you want to calculate your age on a specific past or future date. Instead of working through different month lengths and leap years manually, you can enter the dates and get the result instantly.
Understanding age calculation
Age is usually expressed in completed years, but an exact age also includes the remaining months and days. For example, someone may be 30 years, 4 months, and 12 days old rather than simply being described as 30 years old.
The calculation starts with the difference between the birth year and the target year. It then adjusts the result based on the birth month and day. This is important because months have different numbers of days and leap years can add an extra day to February.
The DigitalMind Tools Age Calculator performs these calculations automatically in your browser, giving you a quick way to compare two dates without having to calculate the difference manually.
