CalendarIdentifiers.Korean | korean property

Gets the identifier for the Korean calendar.


var korean = Windows.Globalization.CalendarIdentifiers.korean;

Property value

Type: String [JavaScript] | System.String [.NET] | Platform::String [C++]

The string "KoreanCalendar", which is the identifier for the Korean calendar.


The Korean calendar is exactly like the Gregorian calendar, except that the year and era are different.

The Korean calendar system recognizes only the current era.

Leap years in the Korean calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. However, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.

The Korean calendar has 12 months with 28 to 31 days each:

99월 (September)3030
1010월 (October)3131
1111월 (November)3030
1212월 (December)3131


February has 29 days during leap years and 28 days during common years.

The date January 1, 2012 A.D. in the Gregorian calendar is equivalent to the first day of January in the year 4345 of the current era in the Korean calendar.

Because the Korean calendar corresponds to the Gregorian calendar, Korean calendar strings for day of the week names and month names are localized for all supported locales and hence will appear in the language corresponding to the ResolvedLanguage property of the calendar object.
