@GrahamDowns Yeah, it's weird.
It's my main reason why I often use the 24-hour system, even in conversation. It's easier and clear. I leave the interpretation of morning, evening, daytime, nighttime, tonight, today, to the receiver. LOL.
I mean, if we say 21:00 it is clearly understood. The only time I use “a.m.” is if I actually meant the time period between 00:00 and 05:00, since it is usually, at least here in the Philippines, understood as 13:00 to 17:00 “in the afternoon”. Only those of us working in night and graveyard shifts would understand it as 01:00 to 05:00 (a.m.)
Crazy. lol.
