What’s the history/reason departments chose Tuesday at 19:00

[u/OwnMountain703]

I’ve noticed that a lot of fire departments, including my own, hold training on Tuesdays at 19:00. Obviously not every hall follows this schedule, but it seems like a pretty common trend. Does anyone know the history or reasoning behind Tuesday evenings being the ‘standard’ practice night, or how that tradition got started.

This might be a stupid question and I apologize if it is, just one of my weekly shower thoughts I suppose.

You don’t use the colon when you use a 24 hour clock. It’s just 1900.

Give me ISO 8601 or give me death.

2025-08-27T03:19:42.500-04:00. (3:19am and 42 seconds and 500 milliseconds Eastern Daylight Time -- a negative four hour offset from UTC)

or

2025-08-27T07:19:42.500Z (same thing, but in UTC)

Multiple date systems exist. Anyone not using 8601 is wrong :)

(I may be just a bit bitter because my day job involves frequent correlation of massive computer log files across multiple timezones, and there is still many systems out there using whatever they started using in the anything goes days of 1990s computing and I spend way too much time figuring out what timezones any given log file uses.)

I do not care. You’re wrong and not a fireman. Good luck!

Your “pikepole” lol okay.

Are you okay?
