There are a few different ways that you can calculate someone’s birth date from their age in Excel. One way is to use the DATEDIF function. This function calculates the number of days, months, or years between two dates. To use this function, you would need to know the person’s age and the current date. For example, if someone is 25 years old today, you would use the following formula: =DATEDIF(TODAY(),25,"y") This would give you the person’s birth date (assuming they were born on January 1st).
Another way to calculate someone’s birth date from their age is to use the YEARFRAC function. This function gives you the fraction of a year between two dates. So, if someone is 10 years old today, you would use the following formula: =YEARFRAC(TODAY(),10) This would give you their birth date (again assuming they were born on January 1st).
You could also use a combination of these two functions to get more accurate results. For example, if someone is 10 years and 3 months old today, you could use the following formula: =DATEDIF(TODAY()-3/12,10,"y") This would give you their birth date (assuming they were born on April 1st).
If you have a list of ages and need to calculate the corresponding birth dates en masse, there are a few different ways that you can do this as well. One way is to create a column next to your ages and then use either of the above formulas for each row. Another way is to use an array formula with one of these functions. For example, if your ages are in column A and your current date is in cell B1, you could use the following array formula: =B1-(ROW(A1:A100)/100)*365 This would give you an array ofbirth dates corresponding to each age in column A (assuming that all of these people were born on January 1st).

How do I calculate age in mm/dd/yyyy in Excel?
There are a few different ways that you can calculate age in Excel, depending on the format of your data.
If you have the person’s birthday in one cell in mm/dd/yyyy format, you can use the following formula to calculate their age: =DATEDIF(birthday,TODAY(),"y") & " years old"

How do I calculate age in Excel without Datedif?
There are a few different ways to calculate age in Excel without using the DATEDIF function. One way is to use the YEARFRAC function. This function returns the number of years between two dates, based on a 365-day year. For example, if you have a date in cell A1 and another date in cell B1, you can use the following formula to calculate the number of years between those two dates:
=YEARFRAC(A1,B1)
Another way to calculate age in Excel is to use the INT function. The INT function rounds a number down to the nearest integer. So, if you have a date in cell A1 and another date in cell B1, you can use the following formula to calculate the number of years between those two dates:
=INT((B1-A1)/365)
You can also use this method to calculate age in days, months, or years. To do this, simply change the 365 value in the formula to 30 for days, 12 for months, or 1 for years.
How do I use the date function in Excel?
The date function in Excel can be used to return the current date and time, or to return a date and time in the future or past. To use the date function, enter =DATE(year, month, day) into a cell.

How do I calculate 25th birthday in Excel?
There are a few different ways that you can calculate someone’s 25th birthday in Excel. One way is to use the DATE function. This function takes three arguments – the year, month, and day. So, to calculate someone’s 25th birthday, you would use the following formula:
=DATE(YEAR(TODAY()),MONTH(TODAY()),DAY(TODAY())+25)
This will give you the date of their 25th birthday. Another way to do this is to use the EDATE function. This function takes two arguments – the start date and the number of months to add. So, to calculate someone’s 25th birthday using this method, you would use the following formula:
=EDATE(TODAY(),25)
Both of these methods will give you the same result – the date of someone’s 25th birthday.
