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
