#632 Continued: Fuzzy month years logic for time span humanize extensions

 TimeSpan.FromDays(7).Humanize(maxUnit: TimeUnit.Day) => "7 days"    // instead of 1 week
 TimeSpan.FromMilliseconds(2000).Humanize(maxUnit: TimeUnit.Millisecond) => "2000 milliseconds"    // instead of 2 seconds
 ```
+The default maxUnit is `TimeUnit.Week` because it gives exact results. You can increase this value to `TimeUnit.Month` or `TimeUnit.Year` which will give you an approximation based on 365.2425 days a year and 30.436875 days a month. Therefore the months are alternating between 30 and 31 days in length and every fourth year is 366 days long.
+```C#
+TimeSpan.FromDays(486).Humanize(maxUnit: TimeUnit.Year, precision: 7) => "1 year, 3 months, 29 days" // One day further is 1 year, 4 month
+TimeSpan.FromDays(517).Humanize(maxUnit: TimeUnit.Year, precision: 7) => "1 year, 4 months, 30 days" // This month has 30 days and one day further is 1 year, 5 months
