Returns the year.
This method is obsolete, and is provided for backward compatibility only. Use the getFullYear method instead.
In Internet Explorer 3.0, and then in Internet Explorer versions starting with Internet Explorer 9 standards mode, the value returned is the stored year minus 1900. For example, the year 1899 is returned as -1 and the year 2000 is returned as 100.
In Internet Explorer 4.0 through Internet Explorer 8 standards mode, the formula depends on the year. For the years 1900 through 1999, the value returned is a 2-digit value that is the stored year minus 1900. For dates outside that range, the 4-digit year is returned. For example, 1996 is returned as 96, but 1825 and 2025 are returned as is.
