Ok, so, remember that some regions are strange and use 12h time, including mine! (I know that many countries are on a 24h clock, which would resolve the issue.) So, here is your wordplay time-riddle of a sort. This is the sentence on my local city watering page. It looks pretty straightforward until you start thinking through it.
My watering “days” are supposed to be Monday and Thursday. (Watering=Irrigation.) Here are the rules:
Irrigate only between the hours of midnight to 10 a.m. and from 6 p.m. to midnight on assigned days
So, what days can I water?
P.S. This is not made up - this is really the rules in my city. I read the rule several times over and found some problems with it, depending on interpretation.
