How to Find the Age of a person in ExcelĬalculating the number of days elapsed between 2 dates and getting a number is good, but if you want to calculate the Age of a person, having the difference in days isn’t much useful.

If you subtract the earlier date from the current date, you will get a positive number, and when subtracting the current date from a previous date will give you a negative number. Keep in mind that whenever you use this formula, you may receive a positive value or a negative value, depending on how you subtract dates. The number obtained is the number of days difference between the two dates. The above formula will result in a number being shown in cell C2. So in our case, we will subtract the date of birth from Today’s date.Īs an example, if the cell A2 contains the date of birth and the cell B2 contains Today’s date, then we can compute the difference between the two dates in cell C2 with the following formula:

This can be achieved by subtracting the second date from the first date. Instead of making future or past dates, you might already have a date, like the date of birth, and now you want to find the age of a person. Both the TODAY() & NOW() are dynamic functions, and every time any other function is evaluated in Excel, the Today & Now functions would get updated too to the latest current date and time. When you use NOW(), you get the date, along with the current time. If you want to see the date with time, you can use the equivalent time function of Excel – NOW() Similarly, you can add or subtract any number of days from a starting date by using this method. This makes it easy to make other dates, like tomorrow and yesterday, with the help of the today function. Simply write =TODAY(), and you will get today’s date. This is an empty function and does not take any arguments. You can find the current date by using the Excel function TODAY. To tweak the way dates appear, you can change the format by picking up a suitable Custom Format. Now we can perform arithmetic with the dates, as they are not really “dates” but rather “numbers”.ĭo take note that based on your regional settings, you might see the date pre-formatted as DD/MM/YY or MM/DD/YY.įurther, you might see a two-digit year or a four-digit year.

The serial number you get might be higher or lower than this number, depending on the date you have keyed in. You’ll see a large number appear instead of the date. If you don’t believe me, simply type a date and then change its type from Date to General. This first date was numbered 1, and then subsequent dates were calculated by adding days to this number. This serial number starts from 1-March-1900. So when you type a date in Excel, it is converted to a number – a serial number to be exact. This trend was started by Lotus 1-2-3, the spreadsheet that predates Microsoft Excel. So a Date value is stored as a number in Excel. But strangely, Microsoft Excel has no special way of determining dates as a Date data type. In the format section, you will even see it as a Date Format. When you type a date in Excel, it appears as a Date.
