Depending on whether this code is in a hotpath (and considering how "elementary" it is, I figure that's a possibility), this could very well be a significant speed improvement.

Though I'd say that only excuses it if it's truly an elementary function (and not one line as part of a larger function), as otherwise it's unreadable garbage. But on its own it:

has a clear purpose
(presumably) isn't reimplementing functionality
is easily tested
can be modified with no side effects (besides breaking your calendar, but that's beside the point)

It's one line as part of a larger function. Also, it doesn't actually say weekend, it just executes some other functionality if !(day % 6). I made it more readable so that everyone here could understand what it does
