Question

How to calculate days in years and months in c#?
per example :

If
1. days = 385 then I need to display Year= 1.1 (i.e. 1 year 1 month)
2. days= 234 then I need to display year =0.7 (i.e 0 year 7 months)

How can we calculate in c#?

I did for days=234 /365 and result is coming 0.64 (i.e. 0 year 6 months). But actually it is 7 months.

How to get accurate year and months.

Answer 1

Assuming a month of exactly one-twelfth of a year, and that you want ignore partial months (based on your saying you expect 7 from your example with 7.688 months, then:

int days = 234;
double years = (double)days / 365.242199;
int wholeYears = (int)Math.Floor(years);
double partYears = years - wholeYears;
double approxMonths = partYears * 12;
string horribleFormat = string.Concat(wholeYears, ".", approxMonths);
