Maybe you wish to inspect if such function exists by doing: {C-h f general-holidays RET} And if it does not exist, it will not work. I can see that variable `holiday-general-holidays' exists. To nullify the variable you can do: (setq holiday-general-holidays nil) You may also use the {M-:} to open up prompt for evaluations. For example: {M-: holiday-general-holidays RET} And you may see there are some values under that variable. In the next step you may evaluate nullify it: {M-: (setq holiday-general-holidays nil) RET} and then verify again what is the value of variable: {M-: holiday-general-holidays RET} Any time you wish to find out if variable exists I suggest that you use {C-h v} > (local-holidays nil) > (christian-holidays nil) > (hebrew-holidays nil) > (islamic-holidays nil) ^ I do suggest using completion package ivy, you may install it with: {M-x package-install RET ivy RET} as it is more visual when searching for variables. If I have ivy installed and I bring cursor to above `islamic-holidays' then I can just press {C-h v} and `ivy' will show me completion and locate the highlighted line on the variable if such variable exists. If it does not exists I will get first item highlighted. Otherwise if you use the built-in Emacs completion and you press {C-h v} to search for variable then I recommend using `*' joker character to search for variables. Let us say you search for something containing "islamic", you would do: {C-h v *islamic TAB TAB} Then you get the list such as: Possible completions are: calendar-islamic-all-holidays-flag diary-islamic-entry-symbol holiday-islamic-holidays and you can find out which variable exist related to "islamic" and inspect such variables.
