Function Age (Date1, Date2) - I need date1 if I know the result of the function

Hello everyone,

I need help to solve the problem. I use the Age function which uses two parameters, ie two dates between which the function returns the number of years, months and days as a result.
Example:
Age ("19690513", "20051010")
// Returns "00360427" which means 36 years, 4 months and 27 days

I need the first date if I know the result and the second date.
If anyone has an idea or knows the solution to this problem, I would be very grateful.

Thanks in advance and best regards

MyDate1 is date = MyDate2
MyDate1..Year-=36
MyDate1..Month-=4
MyDate1..Day-=27
info(MyDate1)

Thanks Argus

It is a solution that works.
