Calculating age from date of birth (DOB) is a common task in various fields such as finance, healthcare, and education. In Google Sheets, you can easily calculate age from DOB using formulas and functions. This blog post will guide you on how to calculate age in Google Sheets from DOB, including the importance of calculating age, the different methods to calculate age, and troubleshooting common issues.
Importance of Calculating Age
Calculating age is an essential task in various industries. For instance, in finance, calculating age is crucial for determining loan eligibility, insurance premiums, and investment strategies. In healthcare, calculating age is important for tracking patient’s medical history, determining medication dosages, and predicting health risks. In education, calculating age is important for determining student’s eligibility for certain programs, tracking student’s progress, and predicting graduation dates.
Calculating age accurately is also important for legal and administrative purposes. For example, in the United States, the minimum age requirement for voting is 18 years old. Calculating age accurately ensures that individuals are not denied their right to vote due to incorrect age calculations.
Methods to Calculate Age in Google Sheets
There are several methods to calculate age in Google Sheets, including using formulas, functions, and add-ons. Here are some of the most common methods:
Method 1: Using the DATEDIF Function
The DATEDIF function is a built-in function in Google Sheets that calculates the difference between two dates. To calculate age using the DATEDIF function, you can use the following formula:
| Formula | Description |
|---|---|
| =DATEDIF(A2,B2,”y”) | This formula calculates the difference between the dates in cells A2 and B2 in years. |
Where A2 is the date of birth and B2 is the current date.
Method 2: Using the TODAY Function
The TODAY function returns the current date. To calculate age using the TODAY function, you can use the following formula: (See Also: How to Make an Inventory Sheet in Google Sheets? Easy Steps)
| Formula | Description |
|---|---|
| =YEAR(TODAY())-YEAR(A2) | This formula calculates the difference between the current year and the year of birth. |
| =MONTH(TODAY())-MONTH(A2) | This formula calculates the difference between the current month and the month of birth. |
| =DAY(TODAY())-DAY(A2) | This formula calculates the difference between the current day and the day of birth. |
Where A2 is the date of birth.
Method 3: Using the EOMONTH Function
The EOMONTH function returns the last day of the month. To calculate age using the EOMONTH function, you can use the following formula:
| Formula | Description |
|---|---|
| =YEAR(EOMONTH(TODAY(),0))-YEAR(EOMONTH(A2,0)) | This formula calculates the difference between the current year and the year of birth. |
| =MONTH(EOMONTH(TODAY(),0))-MONTH(EOMONTH(A2,0)) | This formula calculates the difference between the current month and the month of birth. |
| =DAY(EOMONTH(TODAY(),0))-DAY(EOMONTH(A2,0)) | This formula calculates the difference between the current day and the day of birth. |
Where A2 is the date of birth.
