Carbon today() vs. now()

Beware of Carbon::today() vs. Carbon::now(). They are not synonyms. The former is equiv. to Carbon::now()->startOfDay().

This is important, especially in test environments. If you're thinking that Carbon::today() is actually today... well I suppose it is, but in what timezone?

I had a test that was doing something calculated off of Carbon::today()->subDays(1) and that is not equal to Carbon::now()->subDays(1).
