12AM to 12 PM

[Dr Jekyll]

According to the paper South Bucks will see snow between midnight and 12PM tomorrow. I think they mean between midnight 26/12 and noon 27/12 because otherwise they'd say midnight to midnight. But why not be clear?

12 is neither am or pm, in my opinion. It's the moment time changes between the two. Well, in South Bucks anyway, maybe other less civilised parts of the UK have a different system

[JulianPH]

Just as 11:59am is the last minute in the morning 12:00pm is the first minute in the afternoon.

So 11:59pm is the last minute of the current day and 12:00am is the first minute of the morning.

It is really quite obvious!

Edited to remove the unintended 12m that snuck in when I forgot to put 00 betwen the : and the p!

It is clear.

I’ve always thought there is no such thing.

AM means before noon and PM means after noon. Therefore 12 noon is just noon and 12 midnight is just midnight (or both 12 AM on one day and 12 PM on the following day).

I could be wrong though.

They walk among us, folks.

No, 11:59 and 59 seconts is the last second of either am/pm period. 12:00 and 0 seconts becomes the precise starting point of the next am/pm period.

Otherwise, would you still clasify 12:30 in the afternoon to be am? Also we celebrate New Year at exactly midnight (12:am) as this is the exact start of the first day of the new year.

There is no 0 on the clock, 12 is the only number at the top of it. Confusing.

Why can’t they use a 24 hour time theme? 00:00 to 12:00?

[motco]

This irritated me for years until I stood back and realised that I cannot change idiots. Likewise quoting distances in hours. On a bicycle? On a horse? Why not measure height in minutes or temperature in flower petals? Stop worrying; they will carry on whatever you do.

[glenrobbo]

The military uses 23:59 hrs / 00:01 hrs for that midnight thing, and 12:00 hrs for noon.

No confusion there. ( Apart from whether it's local time or Greenwich Mean Time. ( GMZ or Zulu. GMZ is the norm. )

So an hour after 12pm is 13pm?

12am - midnight
12 pm - midday

Couldn't be clearer. 12pm is noon. So a 12 hours period during which you can expect to see snow.

I have several clocks that display four zeros once each day.

[Zarco]

Glad we cleared that up

Of course it is, how could it not be?!

12:00pm = noon (the start of the afternoon).

12:00am = midnight (the start of the morning/day).

It's not difficult!

Hmm, so an hour after 13pm is 14pm?

AM = Ante Meridian (before midday).
PM = Post Meridian (after midday).

12:00 AM is the first minute of the day, so 12:00 AM on 26/12 is 36 hours before 12:00 PM on 27/12.

I use 24 hour clocks so AM and PM are meaningless concepts to me.

How can 12 PM be midday if PM means after midday?

Because the instant a clock moves from 11:59 and 59 seconds to 12:00pm you have moved into the afternoon.

12:00pm is only exactly 12:00pm for a period that is impossible to calculate before the smallest fraction of a second moves it beyond the precise point of midday. So 12:00pm is both midday and post midday at the same time.
