Run Hazel rule based on the day of the week

I LOVE HAZEL.

Now that I made that clear, let’s get into the actual stuff.

As many of you will know, Hazel is a great Mac utility that lets you automatically do stuff to files. You can move files based on their name/size/extension/you name it, and do a bunch of cool stuff with them, without ever having to write a single line of code.

Today I needed to write a rule that would act based on the day of the week a file was created¹.

Turns out, Hazel can do that (not much of a surprise, huh?), but this time I didn’t find it particularly intuitive how to do it. You have to use the “Occurs after” function on the “Created date” (or any date, actually). In this example, this rules will only run on files that have been created after 00.00 on Mondays only, i.e. any file created on Mondays.

(Don’t be confused by the weird names on the “day of week” submenu, they’re just the Italian names for the days of the week.)

The cool thing is that you can select more than one day, so as always Hazel is very flexible.
