On GNU ELPA search for holidays and download one of those packages and
you may use such to make your own.

See example here:

https://github.com/abo-abo/netherlands-holidays

Also see in Emacs Manual:

File: emacs.info,  Node: Holiday Customizing,  Next: Mayan Calendar,  Prev: Calendar Customizing,  Up: Advanced Calendar/Diary Usage

31.13.2 Customizing the Holidays
--------------------------------

   The general holidays are, by default, holidays common throughout the
United States.  In contrast, ‘holiday-local-holidays’ and
‘holiday-other-holidays’ are both empty by default.  These are intended
for system-wide settings and your individual use, respectively.


   For example, suppose you want to add Bastille Day, celebrated in
France on July 14 (i.e., the fourteenth day of the seventh month).  You
can do this as follows:

     (setq holiday-other-holidays '((holiday-fixed 7 14 "Bastille Day")))

     (setq holiday-other-holidays
           '((holiday-hebrew 10 2 "Last day of Hanukkah")
             (holiday-islamic 3 12 "Mohammed's Birthday")
             (holiday-julian 4 2 "Jefferson's Birthday")))
