@YEAR — returns the year (1601 through 9999) for the specified date. The date may be in any input date format supported by this plugin, and must be a valid date within the supported range.

Syntax:
%@YEAR[date,infmt]

datethe date to examine; defaults to today’s date
infmtthe input date format, used to interpret ambiguous dates

• Incompatibility: In 4NT / Take Command v10 and earlier, the native @YEAR function will return a two-digit year if the input date uses a two-digit year. I don’t like this behavior, and choose not to replicate it. My @YEAR will always return four digits.
