Well, that’s not “the month” at all, though. At least not something I’d use outside of getting a rough idea for setting the next meeting, and absolutely wouldn’t use in code (but it’s probably fine for a todo - I’m complicating things, sorry ;-))
Edit: but perhaps that’s the custom used at many places and I’m just not aware.
