When specifying a date format for the jQuery UI datepicker YY is a 4 digit year and Y is a 2 digit year:
YY = 2011
Y = 11
See http://docs.jquery.com/UI/Datepicker/formatDate
Was curious why this is.
All of the single character variations (d, m, y) are the short version. Double is long version. Since the short version of a year is two digits, using
yyspecifies the long version, which is four digits. The format is not directly related to the number of digits that the date outputs.Just as M (single) means: “Jan, Feb, Mar, Apr”, and MM (double) means: “January, February, March, April”. The same goes for all of the format chars.
This is unlike the standard format for PHP, which may confuse some.
The chosen format was to meet the web standards (RFC)s for date formatting.
