How often does this actually happen? It’s never been common for my European coworkers or my American ones. I rarely schedule meetings with Europe in the Eastern TZ afternoon and the same with India. If I say I’m deploying at 11pm on Saturday everyone understands.

"Let's meet at your 4pm Tuesday." "The flights for the off-site land on 4/2 at 3pm local time."

I’m deploying on Friday night at 11:15pm Eastern or 5:15am in the UK.

12pm is something that you routinely see in the "day" life - opening/closing times, appointments, etc. That's the one I know.

12am is the other one, so it's at night. I have to deduce every time I see it.

I always just write 11:59 P.M or 11:59 A.M. to make this less confusing. Especially because the people setting the time are prone to making the same mistake when scheduling the event. For example: ...the discount expires at 11:59 P.M. on Thursday, March 24, 2022. is far less confusing than: ...the discount expires at 12:00 A.M. on Friday, March 25, 2022. At a quick glance, it's easy to think this means late Friday ni…

This help domestically, but not across cultures that don't use 12 hour time.

Do Europeans just not have analog clocks or watches anymore?

I also found the "European" remark a bit weird.

I'm American so I don't really know, do Europeans generally ignore how AM/PM works?

IIRC the Romans created the system, so I'd find it really weird if it had dissapeared from common usage around there.

Also, every single picture I've found of a clock tower from Europe seems to follow a 12-hour convention.

You can always just say 23:59 instead of 12:00 A.M.

We're discussing time formats. Some Europeans would complain when we'd write "I'm deploying on Friday morning at 10am Eastern or 3pm CET." instead of "15:00 CET"

There's no logic behind this. Even if you go by the reasoning that 12 PM is noon because any time after exactly 12 PM sharp is post-meridian if the meridian is exactly at 12, it shouldn't be 12 but 0. Having an intentional off-by-one error in your date format is simply bad design and counterintuitive.

The 12 hour date format with AM/PM is asking for trouble and it's at least partially their fault that you got this wrong, especially if they schedule appointments at unusual times and expect you to find noon and midnight equally reasonable. They could have avoided this easily but their lack of accomodation shows an intentional disregard.

If it's any consolation, Pearson is infamous for horrible exam designs, so at least they're not uniquely shitty towards non-Americans.
