Calculating age in Excel is a valuable skill for various purposes – whether it’s for project planning, event coordination, or general data analysis. In this article, we will learn how to calculate age from date of birth (DOB) using Excel functions.
1. Basic Age Calculation:
To start with the basics, you can use the DATEDIF function to calculate the age of a person. The syntax for this function is:
=DATEDIF(Start_date, End_date, Unit)
Here’s how to use the DATEDIF function to calculate age:
Step 1: Enter the date of birth in one cell (let’s say, A1)
Step 2: Enter the current date in another cell (let’s say, A2). You can use =TODAY() function to get today’s date automatically.
Step 3: Use the DATEDIF function to calculate age by typing in the formula =DATEDIF(A1,A2,”y”) where A1 refers to the cell with DOB and A2 refers to the cell with today’s date. The “y” part represents years as unit.
This will give you the age of a person in years.
2. Calculate Age with Years, Months and Days:
If you want a more precise calculation including years, months and days, you can use the following steps:
Step 1: Calculate years using the same DATEDIF function as shown above =DATEDIF(A1,A2,”y”)
Step 2: Calculate months component using =DATEDIF(A1,A2,”ym”)
Step 3: Calculate days component using =DATEDIF(A1,A2,”md”)
Step 4: Combine all three components using CONCATENATE function in a new cell like this: =CONCATENATE(DATEDIF(A1,A2,”Y”),” Years “,DATEDIF(A1,A2,”YM”),” Months “,DATEDIF(A1,A2,”MD”),” Days”)
This formula will display the age with years, months and days.
3. Calculate Age in Decimal:
If you want to calculate age as a decimal, you can use the following formula:
=YEARFRAC(Start_date, End_date, [Basis])
Where Start_date and End_date are the date of birth and current date respectively. The Basis is optional and determines the counting method – it can be set between 0 and 4.
The simplest way to use this function is:
=YEARFRAC(A1,A2)
This will return the age in decimal format for the given dates.
In conclusion, calculating age using Excel is easy and efficient. By leveraging these various functions, you can analyze your data in different formats to gain valuable insights. Whether you want to calculate age in years, months and days or as a decimal figure, Excel allows you to customize your calculations according to your needs.
How to Calculate Age in Excel from Two Dates
Calculating age in Excel can be an essential function, especially when working with dates and needing to know chronological information for specific tasks. In this article, we will walk you through the simple steps on how to calculate age in Excel using two dates.
There are multiple ways to accomplish this, but the most common methods include using the DATEDIF function or a combination of YEARFRAC, INT, and TODAY functions.
Method 1: Using DATEDIF Function
1. Open Microsoft Excel and input your data. You should have columns with birthdates (or start date) and current date (or end date).
2. Select the empty cell in the row you want to calculate the age difference. We will apply the DATEDIF function to this cell.
3. Type in the following formula:
=DATEDIF(A2,B2,”y”)
In this formula, ‘A2’ represents the birthdate cell, ‘B2’ is the current date or end date cell, and ‘y’ tells Excel to calculate results in years.
4. Press Enter to execute the formula.
5. To apply this formula to other cells, click on the bottom right corner of your result cell and drag it down through your data. This will copy and paste the formula while updating it for each corresponding row.
Method 2: Using YEARFRAC, INT, and TODAY Functions
1. Open Microsoft Excel and input your data. You should have columns with birthdates (or start date).
2. Select the empty cell in the row you want to calculate the age difference based on today’s date.
3. Type in the following formula:
=INT(YEARFRAC(A2,TODAY(),1))
In this formula, ‘A2’ represents the birthdate cell, ‘TODAY()’ function retrieves today’s date automatically, ‘YEARFRAC’ calculates the difference in years between two dates, and the ‘INT’ function omits the decimals displaying only integer values.
4. Press Enter to execute the formula.
5. To apply this formula to other cells, click on the bottom right corner of your result cell and drag it down through your data. This will copy and paste the formula while updating it for each corresponding row.
Now you know how to calculate age in Excel using two dates with the help of DATEDIF and YEARFRAC functions! Both methods provide accurate results and can be adjusted depending on your specific needs. The next time you need to work with age calculations in Excel, you will have reliable formulas at your fingertips.
