Knowing your exact age is important for many everyday and official purposes. Government forms, school admissions, employment applications, competitive examinations and other documents may require your age to be calculated from your date of birth.
Manual age calculation can sometimes be confusing because different months have different numbers of days and leap years can affect date calculations. A simple step-by-step method can help you calculate your age correctly.
How to Calculate Age From Date of Birth
The basic method is to calculate the difference between the date of birth and the date on which the age is being calculated. The result can be expressed in completed years, months and days.
Step 1: Calculate Completed Years
First, subtract the birth year from the current year. If the birthday has not occurred yet in the current year, one year needs to be deducted from the result.
Step 2: Calculate Remaining Months
Next, compare the current month with the birth month. If the current month comes before the birth month, the year calculation needs to be adjusted and the remaining months calculated accordingly.
Step 3: Calculate Remaining Days
Finally, compare the current day with the birth day. If the current day is earlier, one month is borrowed and the number of days in the previous month is considered.
Example of Age Calculation
Why Leap Years Matter
Leap years contain an additional day in February. This can be important when calculating the exact difference between two calendar dates. A date-based calculation should take the actual calendar dates into account.
This is one reason why an online date calculator can be more convenient than manually counting days between two dates.
