The property is being set to a Calendar that is not valid for the current culture.


The property is being set and the DateTimeFormatInfo is read-only.

The Calendar property accepts only calendars that are valid for the culture associated with this instance of DateTimeFormatInfo. For example, if the current instance originated from the DateTimeFormat property of an "en-US" CultureInfo object, this property can accept only the calendars that are valid for the "en-US" culture. The CultureInfo.Calendar property specifies the default calendar for the culture and the CultureInfo.OptionalCalendars property specifies other calendars supported by the culture.

Changing the value of this property affects the following properties as well: MonthNames, AbbreviatedMonthNames, DayNames, AbbreviatedDayNames, CalendarWeekRule, FirstDayOfWeek, FullDateTimePattern, LongDatePattern, ShortDatePattern, YearMonthPattern, and MonthDayPattern.

For example, if the culture of the current thread is Japanese, this property accepts JapaneseCalendar, Localized GregorianCalendar, or USEnglish GregorianCalendar. When the JapaneseCalendar is used, the default long date specifier is "gg y'\x5e74'M'\x6708'd'\x65e5'". When the Localized GregorianCalendar, is used, the default long date specifier is "yyyy'\x5e74'M'\x6708'd'\x65e5'".
