Koby Posted September 12, 2015 Report Share Posted September 12, 2015 This may seem like a dumb question, but think about it... Why is noon officially coined as 12PM?When you see the below chart, maybe it'll put things into a better perspective:1AM2AM3AM4AM5AM6AM7AM8AM9AM10AM11AM12PM1PM2PM3PM4PM5PM6PM7PM8PM9PM10PM11PM12AMSee what I mean? We count from 1 to 11 and suddenly 12 is different. As it's setup we're basically counting 12 to 11. So we're doing 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. I really can't be the only one am I that thinks this is silly and logically speaking noon should be 12AM and midnight 12PM to coincide with the count frame. Why did they decide to this is? Is there some reason behind it that I don't know or I'm just not seeing?What do you think?The 12-hour clock is a time convention in which the 24 hours of the day are divided into two periods: a.m. (from the Latin ante meridiem, meaning "before midday") and p.m. (post meridiem, "after midday"). Given that definition, we can say it's accurate as-is, but that doesn't mean it's the logical solution either. 1 Quote Link to comment Share on other sites More sharing options...

Baal Posted September 13, 2015 Report Share Posted September 13, 2015 Noon can't be 12AM because 12:00:00.0001 is past noon, simple.12h:12m means that its 12th minute of the 13th hour not 12th minute of 12th hour. The same goes for counting frames in Aegisub. We start with frame number 0 at 00:00:00.0000 because at that time that frame did not end its display time, but if you were counting frames then you would say its frame number 1. I hope it makes sense :3 Quote Link to comment Share on other sites More sharing options...
highland3r Posted November 22, 2015 Report Share Posted November 22, 2015 Because pm starts at noon and am at midnight. it's only a 24hour day and half is one and half is the other. I personally go by 24hour so there is no am or pm. You know what I mean. Quote Link to comment Share on other sites More sharing options...
ani-me Posted November 22, 2015 Report Share Posted November 22, 2015 Believe it or not, I too have wondered the same thing a few times Also, this sudden switch also confused me a lot when I was young.

I hope it makes sense :3 Yes, but as with Aegisub, shouldn't the time too start with 00:00, instead of 12:00, because only then would it make more sense. Specially this is what it really is, and the same convention is followed in case of 24-hour format, a day starting at 00:00, instead of 12:00PM. In fact even the division of 60 seconds & minutes seems weird to me. 10 or 100 division are easier. Anyways, we can keep going into conventions are their endless meaningless world. But at some other time I guess. Quote Link to comment Share on other sites More sharing options...

wjbraden Posted November 22, 2015 Report Share Posted November 22, 2015 Makes me wonder why Japan uses 24:00-27:00 for their broadcast times. Quote Link to comment Share on other sites More sharing options...

AaronScythe Posted November 24, 2015 Report Share Posted November 24, 2015 12:00 on the dot is noon, but by the time we can conceive of it changing (less than a second) it's already after-noon. So 12pm being 12:00 - don't think of it like that. 00:00 is midnight, 12am as the counter starts there. So it makes sense to have 12pm as noon as otherwise you'd have two different AM 12's I hope this helps Quote Link to comment Share on other sites More sharing options...
PM62 Posted November 29, 2015 Report Share Posted November 29, 2015 24-hour time (commonly used in Europe) thankfully resolves this issue easily since midnight is 0:00/24:00. Quote Link to comment Share on other sites More sharing options...
