How to Calculate age from Date of Birth
Calculating age from the date of birth is a straightforward process, requiring a little bit of arithmetic. You can calculate your age manually using a pen and paper, or you can use an age calculator online. Here are the basic steps to calculate age using a date of birth,
1. Identify the date of birth
The first step is to find out the person’s date of birth. This information can be on an official document such as a passport or birth certificate.
2. Calculate the difference between the year of birth and the current year.
Once you have identified the year of birth, subtract it from the current year to get the difference. For example, if the person was born in 1990 and the current year is 2022, then the difference is 2022-1990 = 32.
3. Determine if the person has had a birthday this year
If the person has already celebrated their birthday this year, then they are one year older. If not, they are still the age they were before their last birthday.
4. Round up or down as necessary
If you are calculating the age for a specific date, round up or down to the nearest month. For instance, if someone was born on January 1, but you’re doing the calculation on June 15, you would add six months to the age calculation.

Leap years occur every four years, making February have 29 days instead of 28. Failing to account for this can result in incorrect age calculations.
2. Using the wrong date format
Different countries have different date formats. For instance, in the United States, the date format is MM/DD/YYYY, while in Europe, it is DD/MM/YYYY. Using the wrong date format can also result in incorrect age calculations.
3. Forgetting to factor in time zone differences
If the person’s date of birth is in a different time zone from where you are doing the calculation, you need to factor in time zone differences to avoid inaccurate age calculations.
