year

An integer that represents the year.

A positive integer that represents the month.

An integer that represents the era.

The number of days in the specified month in the specified year in the specified era.

Exception typeCondition

ArgumentOutOfRangeException

year is outside the range supported by the calendar.

-or-

month is outside the range supported by the calendar.

-or-

era is outside the range supported by the calendar.

For example, in GregorianCalendar, GetDaysInMonth for February returns 28 in a common year or 29 in a leap year.

Notes to Inheritors The derived class must support CurrentEra when it is passed as the era parameter. One way to support CurrentEra is by replacing it with the value stored in Eras[0], which is the value for the current era of the calendar.
