Thanks, Evo and Tsu. My baby sis and I thought it might be fun to take some pictures in our cowboy hats while I was down for a visit.
Here is some Texas pecan pie
*stuffs two large slices of pecan pie into computer* .....
just warmed up in the oven and....
*stuffs two giant scoops of Blue Bell vanilla ice cream into computer*

something to go on top!

Sorry that I never replied yet, its just that when I went to the logic section, there was a "-" on the replies table, so I though man, this is one dead forum, Yes, I belive midnight is technecly not AM nor PM, but according to logic and computers (which has the final say), midnight is AM, the begining of a new day, the sign was wrong, hehe. The sign just said that there was a deal from midnight new years eav, to 1:00 AM new years day, when technecly, it should have said that there was a deal from midnight new years day , to 1:00 AM new years day.

Problem solved :)

I thought people put 12 midnight as 12 MN and noon as 12 N ? There is no PM or AM associated with 12 o clock right?

It was fun for a while, but I missed my injection-molded look!

What most of them said.... Just like 1:00 and 1 second is the turning point from 12 to 1; so is 12:00 and 1 second is the turning point from PM to AM and vice versa.

Well, I guess it depends if they meant to have a 25 hour sale starting actually at midnight of New Year's Eve and running one hour into New Year's morning, or if they had a ONE hour sale from midnight to 1 AM on New Year's morning (what a lame time for a sale if that's really what they meant...I can hear the managers at the staff meeting for that one: "Yep, we're going to have a sale, during the one hour we're guaranteed nobody is going to be out buying videos." I feel bad for the poor schmuck who had to work that night because there was a sale so they couldn't just close early when there were no customers.)

midnight is 00:00 hours, thus AM :rollseyes:

but technically 00:00 on the 25th December is equivalent to 24:00 on the 24th December.. :uhh:
But you never see 24:01 on a clock? Or 24:00 for that matter.

After 24 hours you must start a new day.

12:00AM= Midnight. As French is, Minuit. Mid-day is Midi.

Post Meridian and Ante Meridian is only used in USA rest of the World uses 24 hour time, so..midnight is 00:00 hr.

I think this thread should be retitled: Semantics

Why? Because that's what we're really arguing.

Noon and midnight are completely arbitrary times that we humans created to satiate our anal retentive need to clearly define when one day ended and another day began. Although noon and midnight loosely correspond to the sun being at it's highest and lowest points relative to the observer, this 'time' changes daily.

However, the common usage in the US is for 12 AM to be the start of a day and 12 PM to be noon on that day.

Thus, your sale that started at 12 AM on New Year's Even and ended at 1 AM on New Year's Day was indeed a 25 hour sale... although the language can be quite confusing...

When, oh when, will the US switch to the 00:00 to 23:59 time system?

Cheers...

24 hour time is much easier. I use it in the lab, and sometimes forget to not use it outside the lab, which confuses people. Since I have done experiments that have run 24 hours or longer, and have required helpers at noon and midnight, just to be 100% certain there was no confusion, I just put a note next to the clock time that says "midnight" or "noon" where appropriate. The only other time life gets confusing is when one of those overnight experiments is running the night the clocks change from daylight savings time to standard time or back again. I really wish daylight savings time could be banished. Then I end up having to explain to the lab that the lab is going to live in a time warp until the experiment is done. It's even more fun in the animal facility trying to explain to a group of technicians (people basically paid to clean cages for a living) that the animals don't care about daylight savings time, but they will care about their lights suddenly going on or off an hour later or earlier if the technicians run around changing the clocks timing the light schedule.

So, yep, I'd love to see everyone switch to 24 hour time and do away with daylight savings time.

Have them change the sign to:
We open at lim[x -> 00:00+](X AM)

This question is sort of like that question in the year 2000....."Is 2000 the start of the new millenia, or the end?" To answer that question, the whole 2000 calendar year was still in the 20th century. The year 2001 was the beginning of the new century and millenium. I believe the first year was 1 A.D. and not 0 A.D. Time, however starts at 0, and therefore the new day starts at 0, that is 12:00 AM.

Technically, you can write 12:00 M for noon, and 12:00AM or 12:00PM for midnight since midnight is both before and adfter noon.

Is the average time on earth 0:00 or 12:00?

I know a chemist who refuses to use daylight savings time, not only in the lab but for everything in his life. He prohibits his family from changing the clocks in their house from GMT. He's very, very strange, and has a big white beard. He drives a Volvo with moss growing on its roof. I think one day he's going to live on the top of a cliff in a little white shed with only a snail for company, and only toast for sustenance.

I've known more than a few "eccentric" chemists. I think it's all those toxic chemicals they play with.

Heck, this sounds unlogical to me, 0:00AM should be midnight and non-existent 12:00AM=0:00PM=midi.
Lucky me I don't live in the states, that's for sure! Long live 0:00-lim_{t->24:00}(t) (No offense to the latin language though )
