Additionally, while midnight is usually expressed as 00:00, it is sometimes expressed as 24:00 when it refers to the midnight at the end of a day (and 00:00 when it’s midnight at the start of a day).
So a shop might say it is open from 07:00 to 24:00 on Mondays, even though it could say it’s open from 00:00 to 21:00 on Wednesdays. If it’s open all day on Fridays, it might say it’s open from 00:00 to 24:00.
Just wondering, is “army time” just what Americans call the 24 hour clock, or are there differences between the two?
