Enter birth date.
The first step in calculating age in Excel is to enter the birth date. You can enter the birth date in any date format that Excel recognizes. For example, you can enter it as "1/1/2000" or "January 1, 2000".
- Use a consistent date format.
Make sure you use the same date format for both the birth date and the today's date. Otherwise, Excel may not be able to calculate the difference correctly.
- Enter the date in a cell.
You can enter the birth date in any cell in the worksheet. However, it's a good idea to enter it in a cell that is labeled "Birth Date" or something similar.
- Use the DATE function.
If you want to enter the birth date using the DATE function, you can use the following formula:
=DATE(year, month, day)For example, to enter the birth date of January 1, 2000, you would use the following formula:
=DATE(2000, 1, 1) - Use a date picker.
If you're not sure how to enter the birth date in a cell, you can use the date picker. To use the date picker, click on the cell where you want to enter the birth date and then click on the small arrow that appears next to the cell. A calendar will appear. You can then use the calendar to select the birth date.
Once you have entered the birth date, you can proceed to the next step, which is to enter today's date.
Enter today's date.
The next step in calculating age in Excel is to enter today's date. You can enter today's date in any date format that Excel recognizes. For example, you can enter it as "1/1/2023" or "January 1, 2023".
- Use the same date format.
Make sure you use the same date format for today's date as you used for the birth date. Otherwise, Excel may not be able to calculate the difference correctly.
- Enter the date in a cell.
You can enter today's date in any cell in the worksheet. However, it's a good idea to enter it in a cell that is labeled "Today's Date" or something similar.
- Use the TODAY function.
If you want to enter today's date using the TODAY function, you can use the following formula:
=TODAY()This formula will automatically return today's date in the cell where you enter it.
- Use a date picker.
If you're not sure how to enter today's date in a cell, you can use the date picker. To use the date picker, click on the cell where you want to enter today's date and then click on the small arrow that appears next to the cell. A calendar will appear. You can then use the calendar to select today's date.
Once you have entered today's date, you can proceed to the next step, which is to calculate the difference between the birth date and today's date.
Calculate the difference.
Once you have entered the birth date and today's date, you can calculate the difference between the two dates. To do this, you can use the following formula:
=DATEDIF(birth_date, today_date, "y")
In this formula, "birth_date" is the cell reference for the cell where you entered the birth date, and "today_date" is the cell reference for the cell where you entered today's date.
The DATEDIF function will return the difference between the two dates in years. For example, if the birth date is January 1, 2000 and today's date is January 1, 2023, the DATEDIF function will return 23.
You can also use the DATEDIF function to calculate the difference between two dates in months or days. To do this, you would use the following formulas:
=DATEDIF(birth_date, today_date, "m")
=DATEDIF(birth_date, today_date, "d")
These formulas would return the difference between the two dates in months and days, respectively.
Once you have calculated the difference between the birth date and today's date, you can proceed to the next step, which is to convert the days to years.
Convert days to years.
If you calculated the difference between the birth date and today's date in days, you will need to convert the days to years. To do this, you can use the following formula:
=days / 365
In this formula, "days" is the cell reference for the cell where you calculated the difference between the birth date and today's date in days.
For example, if the difference between the birth date and today's date is 8,520 days, the formula =8520 / 365 would return 23.34.
This means that the person is 23 years and 126 days old. You can use the INT function to truncate the decimal part of the number and get the person's age in whole years. To do this, you would use the following formula:
=INT(days / 365)
In the example above, the formula =INT(8520 / 365) would return 23.
Once you have converted the days to years, you can proceed to the next step, which is to handle leap years.
Handle leap years.
Leap years can complicate the calculation of age in Excel. This is because leap years have 366 days instead of the usual 365 days.
To handle leap years, you can use the following formula:
=DATEDIF(birth_date, today_date, "y") + IF(AND(MONTH(birth_date) = 2, DAY(birth_date) = 29, YEAR(today_date) - YEAR(birth_date) > 0), 1, 0)
In this formula, "birth_date" is the cell reference for the cell where you entered the birth date, and "today_date" is the cell reference for the cell where you entered today's date.
The DATEDIF function will return the difference between the two dates in years. The IF function will add one year to the age if the person's birthday is on February 29th and the current year is a leap year.
For example, if the person's birthday is February 29, 2000 and today's date is March 1, 2023, the formula =DATEDIF("2/29/2000", "3/1/2023", "y") + IF(AND(MONTH("2/29/2000") = 2, DAY("2/29/2000") = 29, YEAR("3/1/2023") - YEAR("2/29/2000") > 0), 1, 0) would return 23.
This is because 2020 and 2024 are leap years. Therefore, the person has had 23 birthdays, even though they are only 22 years old.
Once you have handled leap years, you can proceed to the next step, which is to use Excel formulas to calculate the age.
Use Excel formulas.
You can use Excel formulas to calculate the age of a person based on their birth date and today's date. The following are some of the most common Excel formulas that you can use:
- DATEDIF function.
The DATEDIF function calculates the difference between two dates. You can use this function to calculate the difference between the birth date and today's date in years, months, or days.
- INT function.
The INT function truncates the decimal part of a number. You can use this function to get the person's age in whole years.
- IF function.
The IF function allows you to specify a condition and then return a different value depending on whether the condition is true or false. You can use this function to handle leap years.
- TODAY function.
The TODAY function returns today's date. You can use this function to get the current date and then calculate the difference between the birth date and today's date.
You can use these formulas to create a simple age calculator in Excel. To do this, you would:
- Enter the birth date in cell A1.
- Enter today's date in cell A2.
- In cell A3, enter the following formula:
=DATEDIF(A1, A2, "y"). - In cell A4, enter the following formula:
=INT(A3).
The cell A4 will now display the person's age in whole years.
Format the results.
Once you have calculated the person's age, you can format the results to make them more readable. For example, you can:
- Add a label.
You can add a label to the cell that displays the person's age to make it clear what the value represents. For example, you could add the label "Age" to cell A4.
- Change the font.
You can change the font of the cell that displays the person's age to make it stand out from the other cells in the worksheet.
- Change the font size.
You can change the font size of the cell that displays the person's age to make it easier to read.
- Add a border.
You can add a border to the cell that displays the person's age to make it look more polished.
You can also use the FORMAT function to format the results of the age calculation. For example, you could use the following formula to format the age as a whole number:
=FORMAT(A4, "0")
This formula would round the age down to the nearest whole number.
Consider edge cases.
When calculating age in Excel, it is important to consider edge cases. These are cases where the standard formulas may not work correctly. Some common edge cases include:
- Birth date in the future.
If the birth date is in the future, the age will be negative. To handle this case, you can use the following formula:
=IF(birth_date > today_date, "Birth date in the future", DATEDIF(birth_date, today_date, "y"))This formula will return the person's age if the birth date is in the past. If the birth date is in the future, it will return the message "Birth date in the future".
- Today's date in the past.
If today's date is in the past, the age will be negative. To handle this case, you can use the following formula:
=IF(today_date < birth_date, "Today's date in the past", DATEDIF(birth_date, today_date, "y"))This formula will return the person's age if today's date is in the future. If today's date is in the past, it will return the message "Today's date in the past".
- Leap years.
As discussed earlier, leap years can complicate the calculation of age. To handle leap years, you can use the formula provided in the "Handle leap years" section.
- Dates in different formats.
If the birth date and today's date are in different formats, Excel may not be able to calculate the difference between the two dates correctly. To avoid this problem, make sure that the birth date and today's date are in the same format.
By considering these edge cases, you can ensure that your Excel formulas will calculate age accurately in all cases.
Conclusion:
Calculating age in Excel is a relatively simple task. However, there are a few things that you need to keep in mind to ensure that your calculations are accurate. By following the steps outlined in this article, you can easily calculate the age of a person based on their birth date and today's date.
