Definition and usage

getYear() method can return a two- or four-digit number representing the year.

Syntax

dateObject.getYear()

</script>

Output:

The value returned by getYear is the current Subtracts 1900 from the year (in JavaScript 1.2) and returns the year which is either a 2 or 4 digit year, for example if the year is 2026, the returned value is 2026 so before testing this function make sure JavaScript version.
