How common is to use full stops in dates? And is the following ever used in English: The shop is open from 7 to 21. Is the 24-hour clock ever used in opening hours? --40bus (talk) 20:37, 19 August 2024 (UTC)[reply]

In the United States, 8/19/2024 or 8/19 would be abbreviations (August 19, 2024 the full form). And 24-hour time is strongly associated with military usage, as has been explained before. AnonMoos (talk) 21:54, 19 August 2024 (UTC)[reply]

P.S. See ISO 8601 if you want to see a theoretical international standard. AnonMoos (talk) 21:56, 19 August 2024 (UTC)[reply]

Is there any English-speaking country where 24-hour clock is used in everyday conversation, and phrases like "it is sixteen" are common? --40bus (talk) 05:16, 20 August 2024 (UTC)[reply]

Just the raw number? Not that I've ever encountered anywhere on the globe. If you are using the 24-hour clock, you say "16:00" or "1600", not "16"; you say "from 0700 to 2100", not "from 7 to 21". --Orange Mike | Talk 14:53, 20 August 2024 (UTC)[reply]

In Finnish, it is common to say: Kauppa on auki seitsemästä kahteenkymmeenyhteen. And for example: Kello on kuusitoista. Also, opening hours are typically written like 7-21 or 12-18. Does English ever refer to time periods around whole hours by their 24-hour clock numbers, such as "nineteen" around 19:00? --40bus (talk) 15:55, 20 August 2024 (UTC)[reply]

No, in English that would be so odd as not to be understood at all, whether as numeric or verbal. --Orange Mike | Talk 17:54, 20 August 2024 (UTC)[reply]

In military usage nineteen hundred can be used for 19:00. --Lambiam 21:50, 20 August 2024 (UTC)[reply]

The Finnish way appears to be the standard in much of continental Europe, but the English speakers are different. Now I wonder what English speakers think when they see shop opening hours during a visit to the continent... Any difference between US English and UK English? PiusImpavidus (talk) 08:32, 21 August 2024 (UTC)[reply]

General US English (as opposed to the specific subset US military English) basically never uses 24 hour time. For anything. Ever. -- User:Khajidha (talk) (contributions) 13:57, 21 August 2024 (UTC)[reply]

We Britons use the 24 hr clock quite widely for administration and official purposes, such as shop opening, doctor's appointments, train and bus times etc. However, in conversation, times are usually translated into 12 hr notation, or (less commonly) given as "eighteen forty-five" or "twenty-three hundred". When writing, colons are usually used as time separators (e.g. 14:30), but full stops can be used too. Alansplodge (talk) 17:00, 21 August 2024 (UTC)[reply]

I've never seen it for store hours, class schedules, or broadcast times and I've just checked bus, train, and plane schedules from various parts of the US with no sign of usage. --User:Khajidha (talk) (contributions) 20:21, 21 August 2024 (UTC)[reply]

But how do you say 16:00 or 1600? I can think of many ways. We have lots of "Date and time notation in Foobarland" articles that discuss spoken times, but they all take it for granted that the reader knows how these things are said. Card Zero (talk) 13:25, 22 August 2024 (UTC)[reply]

I (in the UK) would invariably say both as "sixteen hundred". Minutes between 10 and 59 would be said as that number ("sixteen ten", "sixteen twenty-five", "sixteen fifty-nine"). Minutes between 01 and 09 would be the number preceded by "oh" ("sixteen oh five"). This is what train announcers (both human and automated) say anywhere in the UK I've been ("the train at platform eleven is the sixteen thirteen service to Bristol Temple Meads...") so I'd be surprised if there were much variation. Military, police, etc usage will sometimes add the word "hours" after any of these ("sixteen hundred hours"). Proteus (Talk) 14:17, 22 August 2024 (UTC)[reply]

ISO 8601 is not a "theoretical" international standard - it is an actual international standard, and has been since 1988. Mitch Ames (talk) 06:20, 31 August 2024 (UTC)[reply]

Yes, but it has had very little general practical influence on date and time usages in the English-speaking world (as opposed to specialized data-exchange contexts). AnonMoos (talk) 15:49, 31 August 2024 (UTC)[reply]

I don't think I've ever seen periods used to separate dates like that in any material produced by a native English speaker. --User:Khajidha (talk) (contributions) 08:11, 20 August 2024 (UTC)[reply]

Using full stops as date separators is not unknown here in the UK, see Date and time notation in the United Kingdom#All-numeric dates. Alansplodge (talk) 11:27, 20 August 2024 (UTC)[reply]

1. and 2. are easily interpretable as dates, 3. and 4. less so. For 5. and 6. it would make more sense to me if there were no full stop before the dash, e.g. 19-22.8.2024, or 8.19-22.2024. For 7. and 8. the full stop after the date is a little odd, just having 19 August 2024 and August 19, 2024 would make the most sense. GalacticShoe (talk) 15:57, 20 August 2024 (UTC)[reply]

I cannot recall dots being used in dates at all. They may well be, but it's not common here in Australia. And to most people outside the US, 9/11 would mean the 9th of November if it hadn't other wise become famous. HiLo48 (talk) 00:07, 21 August 2024 (UTC)[reply]

Your use of periods after the item numbers here disturbs me more than I can describe. -- User:Khajidha (talk) (contributions) 16:07, 21 August 2024 (UTC)[reply]

a. I b. aim c. to d. confuse :) GalacticShoe (talk) 19:10, 21 August 2024 (UTC)[reply]
