Issues with rounding on date calculations and rounding down function

Hello, 

I hope some can help.

I have some calculation that calculate a persons age based on two columns.  I create a custom column with the following measure:

[Report Date] - [Birthdate]

This gives a column with the number of days between - this figure produced looks correct.  I then add another column changing the days to years using the Time function to change the days to years - this then gives and incorrect figure because it simply divides the days by 365 not taking into account leap years etc.

For example

[30/04/2022] - [13/05/1962] = 21902 days.  His age on 30/04/2022 should be 59 but the days to years does the following:

21902/365 = 60.005

Any help getting a more accurate figure would be much appreciated.

Thanks,
