| Description |
Returns the day of the yearfor the given TheDateTime value.
The GetDayOfYear method converts the ticks value in TheDateTime (1 tick = 0.0000001 seconds since 1st Jan 0001 AD) into an internal representation of years, months, days according to the Calendar culture. It then returns the Day of year value according to this culture.
For example, in the Hebrew Calendar, there are between 353 and 355 days per common year, and 383 to 385 days in a leap year.
