Date of age with fraction

Copper Contributor

Hello everyone!

I usually calculate the date of people turning different ages, but I struggle to calculate when ages are given fraction part. For example, I know my clients birthday and should find date when he/she turns 74,4.

I've tried many functions, but couldn't find a solution. I am tired of calculating on paper, it would be great I could calculate it with the helpm of Excell.

Thanks in advance.

Hello @khujaabbos,

 

That could be:

=[Birthdate]+[Decimal_Age]*365.2422

Note that we account for leap years by using the exact amount of days per revolution around the sun (365.2422 days).

You can use the formula:

=YEARFRAC([DATE])

To verify the decimal age is correct.

I wonder, what is the benefit of such a calculation?

Average lifespan of both males and females are given in this form, and our clients will be recieving insurance benefits till this date. Therefore, I need to know when to stop them recieving insurance benefits.

Hello @PReagan!,

Thank you so much for your reply. Unfortunately, I didn't understand the first part of the reply. Could you show it with an example? And was it supposed to be done on Excell?

 

Thanks in advance.

[Birthday] represents a cell that contains the participants birthday. For example, B1 = 1/1/1946

[Decimal_Age] represents a cell that contain the participants age in decimal format. For example B2 = 74.4

The number 365.2422 represents the exact amount of days in a year.

Using the formula, the date in which the participant turns 74.4 is:

=B1+B2*365.2422 or 5/26/2020

You can use YEARFRAC(B1,B3) to verify that the decimal age is correct.
