I’m pretty sure that “oh, shoot, things got wonky… toss a 13th month in here real quick” is due to people trying to force months to fit weeks.
It’s the opposite of what I was saying about the role that months play in timekeeping & how they work.
ALSO, the same can be said for weeks & leap days… so if it’s a point against months, it’s just as much a point against weeks.
If it’s the USA, then “iced tea” may actually mean “sweet tea” (an American South tradition), which is often prepared something like this:
It may be a stronger tea, but so much sugar gets added (probably 3x what would be used to sweeten tea served hot) that you typically don’t notice any bitterness.
