holiday-moondays.el

This defines calendar events to show with M-x calendar in emacs. Place it in the folder where you load local packages from.

      
(add-to-list 'load-path "~/path/to/local/packages")

;; This defines the holiday-moonday-holidays list
(require 'holiday-moondays)

;; Week starts on Monday.
(setq calendar-week-start-day 1)
;; calendar-holidays is usually a list of religious and secular dates, we
;; replace the default list with only the moondays.
(setq calendar-holidays holiday-moonday-holidays)
;; Show holidays and diary entries when the calendar is opened.
(setq calendar-mark-holidays-flag t
      calendar-mark-diary-entries-flag t)
;; Include the holidays (moondays) in the diary display buffer, instead of
;; showing them in the minibuffer.
(setq diary-list-include-blanks t
      diary-show-holidays-flag t)

The complete list from 2000-2100 is quite long, so it's probably a good idea to filter it for the relevant years. Download with wget and filter with sed for example:

      
wget -O - "https://splendidmoons.github.io/calendars/holiday-moondays.el" |\
    sed '/^(holiday-sexp/ { /\(2022\|2023\|2024\|2025\)/ !d; };' > holiday-moondays.el
