I have an integer 15791 which represents count of days since epoch and equals 27.03.2013, how can do this convert in C#?

public void method1()
{
  ...
  int days_since_epoch = 15791;
  // how convert `days_since_epoch` to "27.03.2013"
}

Thanks!

Adds a number of days to your epoch.

For example:

var epoch = new DateTime(...);  // Your epoch (01/01/0001 or whatever)
var yourDate = epoch.AddDays(days_since_epoch);

Assuming your Epoch date is in a DateTime just use

DateTime epoch = new DateTime(1970,1,1);

int days_since_epoch = 15791;

DateTime converted = epoch.AddDays(days_since_epoch);

Simply use the AddDays method, and once you got your final date, format it as usual in the ToString().

Perhaps:

TimeSpan ts = TimeSpan.FromDays(15791);
DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).Add(ts);

var date = new DateTime(1970,1,1).AddDays(15791);
Console.WriteLine(date.ToString("dd.MM.yyyy"));
