Hello. I've been using Julien Danjou's code to good effect: https://julien.danjou.info/blog/2010/org-mode-and-holidays
Basically, it just advocates adding the following function, which then marks holidays with weekend face for clear viewing: (require 'cl-lib) (setq org-agenda-day-face-function (defun jd:org-agenda-day-face-holidays-function (date) "Compute DATE face for holidays." (unless (org-agenda-todayp date) (cl-dolist (file (org-agenda-files nil 'ifmode)) (let ((face (cl-dolist (entry (org-agenda-get-day-entries file date)) (let ((category (with-temp-buffer (insert entry) (org-get-category (point-min))))) (when (or (string= "Holiday" category) (string= "Vacation" category)) (return 'org-agenda-date-weekend)))))) (when face (return face))))))) Now, however, it has stopped working. Once again I'm receiving the error, cl-return-from: No catch for tag: --cl-block-nil--, org-agenda-date-weekend Previously I repaired this by requiring 'cl-lib and making dolist into cl-dolist; but it no longer seems to be working. I'm not sure what's changed. Any suggestions?
