A two-digit integer that represents the year to convert.

Return Value

An integer that contains the four-digit representation of year.

Exception Type Condition
ArgumentOutOfRangeException year is outside the range supported by the calendar.

Remarks

TwoDigitYearMax is the last year in the 100-year range that can be represented by a two-digit year. The century is determined by finding the sole occurrence of the two-digit year within that 100-year range. For example, if TwoDigitYearMax is set to 2029, the 100-year range is from 1930 to 2029; therefore, a 2-digit value of 30 is interpreted as 1930, while a 2-digit value of 29 is interpreted as 2029.

If year is greater than or equal to 100, the value of year is returned unchanged.
