Why do people use 12:00 pm when the actual time meant is Noon?

Fair enough; what inspired the question was an appointment card from the local doctor, the receptionist wrote ‘12pm’, which was obviously not intended as they close at 4:00 pm.

Isn't the real meaning of noon is when the sun reaches its highest point in the sky. Time zones and daylight savings puts noon and 12:00 pm out of calibration.

It should have read 12 noon or 12.01 pm - and that comes before 4pm. Post meridiem :P

It's like those using the 24 hr clock saying 24.00 hundred hrs for midnight.

There's no such time.

Midnight doesn't register as 24.00hrs  in systems that use it.

It goes 23.59 hrs to 00.01 hrs.

Gnads is wrong:



On a 24-hour clock, when the time transitions from 23:59, the day is over.

The clock then rolls over to 00:00 to start a brand new day, and the very next minute is 00:01.

The sequence runs as follows:23:59 (the final minute of the day)00:00

(midnight, the beginning of the next day)00:01 (the first minute of the next day)


https://en.wikipedia.org/wiki/24-hour_clock

The modern 24-hour clock is the convention of timekeeping in which the day runs from midnight to midnight and is divided into 24 hours. This is indicated by the hours (and minutes) passed since midnight, from 00(:00) to 23(:59), with 24(:00) as an option to indicate the end of the day. This system, as opposed to the 12-hour clock, is the most commonly used time notation in the world today,[A] and is used by the international standard ISO 8601.[1]

12:00pm is midnight, 12 hours post meridiem.

12pm is noon.  - it stands for post meridiem.


Similarly, the counterpart to noon is 12 a.m., which stands for ante meridiem (meaning "before midday") and is used for midnight. Because the clock resets exactly at the meridian (midday), many people avoid 12 a.m. and 12 p.m. altogether to prevent confusion, preferring to just use "midnight" or "noon"

Midnight is both, it’s 12 hours post meridiem and also 12 hours ante meridiem.

"Meridiem" is a Latin word meaning "midday" or "noon".

It forms the basis of the time abbreviations used in the 12-hour clock:

A.M. (ante meridiem, meaning "before noon") and P.M. (post meridiem, meaning "after noon").

Your case is hopeless - you can't be taught anything.  ::)

There are no official standards established for the meaning of 12am and 12pm, but it is generally accepted that 12am means midnight and 12pm means midday. 
The ‘am’ and ‘pm’ stand for ante meridiem and post meridiem – Latin words meaning ‘before the middle of the day’ and ‘after the middle of the day’.

When the clock hits 12:00:00, you have hit ‘meridiem’. So all times before that are ‘ante meridiem’ within the same day, and all times afterwards are ‘post meridiem’, up until the clock hits midnight and a new day begins.

By the time you have seen a clock showing 12:00 at midday it is already post meridiem, and similarly at midnight it is already ante meridiem.

I love your grasp of logical thinking, so when one reaches a point one is already past it.
One would think that if 11:00 pm is 11hours after the meridiem that 12:00pm would be 12 hours past it, after all 12 comes after 11.

Post meridian or PM is all about solar noon:



Solar noon is the exact moment the Sun reaches its highest point in the sky for a specific location,
occurring midway between sunrise and sunset.
At this instant, the Sun crosses your local north-south meridian, and any shadows cast point directly due north or due south.
Because of the Earth's tilted axis and elliptical orbit, clock noon (12:00 PM) rarely aligns perfectly with solar noon.

Depending on the time of year and your specific longitude, solar noon can occur before or after clock noon by up to 15–30 minutes.Tracking the Sun in VictoriaFor residents in Victoria, Australia, the exact time of solar noon depends on the specific date and whether Daylight Saving Time is active.

During the winter months (Standard Time), solar noon typically occurs close to 12:30 PM to 12:45 PM depending on where you are in the state. During the summer, Daylight Saving Time shifts clocks forward, pushing solar noon closer to 1:30 PM to 1:45 PM.

Bobby,
What do you find difficult in the concept that 12:00pm means 12 hours post meridiem or 12 hours after the noon.

I am fully aware that people accept things that are wrong for the sake of convenience or because they don’t think.
The fact that 12:00pm is commonly accepted as noon doesn’t alter the fact that pm means post meridiem and any time defined by it comes after noon.

Christiaan Huygens,[a] Lord of Zeelhem (14 April 1629 – 8 July 1695) was a Dutch mathematician, physicist, engineer, astronomer, and inventor who is regarded as a key figure in the Scientific Revolution.[4][5] In physics, Huygens made seminal contributions to optics and mechanics, while as an astronomer he studied the rings of Saturn and discovered its largest moon, Titan. As an engineer and inventor, he improved the design of telescopes and invented the pendulum clock, the most accurate timekeeper for almost 300 years. A talented mathematician and physicist, Huygens authored the first modern treatise where a physical problem was idealized using mathematical parameters, while his work on light contains the first mathematical and mechanistic explanation of an unobservable physical phenomenon.

Noon is not 12:00am, am is ante meridiem, i.e. 12:00 am is 12 hours before noon therefore it is midnight.

No it is a mere convention, a workaround, a human abstract. The arabic numbers go from 00.00.01 - 12, or a digital clock 0 - 23.59.59. What you are suggesting is 12 comes before 0.  ;)

Similarly, the counterpart to noon is 12 a.m., which stands for ante meridiem (meaning "before midday") and is used for midnight. Because the clock resets exactly at the meridian (midday), many people avoid 12 a.m. and 12 p.m. altogether to prevent confusion, preferring to just use "midnight" or "noon" How can 12 hours after noon be noon, not logical. So at lunchtime it's 12am then after that it's 12:01 pm. I always thought at midnight it's 12am then 12:01 am. Lunchtime is 12pm.     ::)

Lunchtime is midday - dickhead.

There are no official standards established for the meaning of 12am and 12pm, but it is generally accepted that 12am means midnight and 12pm means midday.  The ‘am’ and ‘pm’ stand for ante meridiem and post meridiem – Latin words meaning ‘before the middle of the day’ and ‘after the middle of the day’. When the clock hits 12:00:00, you have hit ‘meridiem’. So all times before that are ‘ante meridiem’ within the same day, and all times afterwards are ‘post meridiem’, up until the clock hits midnight and a new day begins. By the time you have seen a clock showing 12:00 at midday it is already post meridiem, and similarly at midnight it is already ante meridiem.

Not until it 1 second past 12 is it post meridiem.

24-hour clock is less ambiguous.

Saying ‘’12 pm is noon’’, is saying that 12 hours after noon is noon.😀😃😀😃😀😃😀.

I’ll bet that some people still think that 2026 AD is the 27th year of the millennium.

And the convention is wrong, all times on the conventional 12 hour clock are either post meridiem or ante meridiem except noon which is the meridiem.

Noon is the meridiem. It is not Post (after) Meridiem. ::)

Why do people use 12:00 pm when the actual time meant is Noon?

Just my 2 pence worth.....


Designating noon......as 12:00 pm is correct.

e.g.
Q.
Is one minute before noon, stated as 11.59 am....correct ?

Of course it is.


And is 12.07 pm [in the afternoon] a correct designation ?

Of course it is.

Of course they are, it’s 1 minute BEFORE the meridiem and 7 minutes AFTER the meridiem,  which is noon [or 12 noon] which is neither ante nor post, it just is, however 12:00pm is 12 hours post meridiem [12 hours PAST noon] which is midnight.

Saying "12pm is noon" means that its 12 o'clock when the sun is passing its highest point and anytime after that exact time is post meridium, so in the 12 hour cycle any time regarded as PM means the 12 hour cycle starts at 12pm and the time on 12 hour cycles ending in AM start from 12am midnight,

Ticking represents time though. The time bomb is ticking.

As an engineer and inventor, he improved the design of telescopes and invented the pendulum clock, the most accurate timekeeper for almost 300 years. A talented mathematician and physicist, Huygens authored the first modern treatise where a physical problem was idealized using mathematical parameters, while his work on light contains the first mathematical and mechanistic explanation of an unobservable physical phenomenon.

Yes Blooby, what did he invent?

The 12 hour cycle begins at noon and just as 11pm is 11 hours past the meridiem so 12 pm is 12 hours past the meridiem, as the meridiem is 12 noon then 12 hours past it is midnight, therefore the designation 12 pm is midnight.
Simple logic.

Keep going, guys.

Marla - you silly hillbilly.    ;D

I remember having an argument with my year 5 teacher about the 24 hour clock. I kept insisting that the clock goes from 11:59 pm to 12:00 am with that reading. Teacher told me that the clock goes to 0:00 for midnight. He got tired of my persistence and said for me to stay up and see for myself.

I did not bother staying up. Nor did I try and reset the clock to see if it did go to 12:00 am. A few weeks later, my family and I came back from a party at after midnight. The clock read 0:24. My mind was going "damn it". I think the reasoning was that I was still thinking in terms of the 12 hour format using the "am" or "pm" times.

I would lose my mind if I had to put up with 23 hour days or nights every 6 months. I only live 23 degrees south of the Equator. The variations between the seasons are slight, but they put me off. I don't know how people in Melbourne manage.

There were quite few people from south loosing head but they were more affected by polar day rather then night and most were readjusted by 2nd year only 1 out of 100 in 5 years attempted suicide but he had other problems and should have not been on active service.

From the moment humankind decided to fix time in place, after millennia of time travel being an everyday thing... time literally stood still... the reason 24 hours per day was selected was because early proto-humans had six fingers on each foot and six toes on each hand... so they could effectively count down the hours..

Anyone who has not noticed that time literally stands still when it is hot and boring or you are attending a political speech or similar ... but accelerates once you are doing something enjoyable is .... a bit slow.... maybe thirty or fifty minutes on the hour ..... proto-humans always knew that time was malleable, and that the timeosphere was susceptible to a human mind properly trained.. you could count your toes on it...

It may not take longer to absorb a political speech etc - but it sure seems that way.... giving the clearest indication that time is subjective.... and is thus amenable to being manipulated...  cats know that - have you ever seen a cat teleport instantly when thunder cracks right over the roof?

The science has been lost with the rigor of modern physics...

Using 24 finger system proto-humans never missed a meal time but why did they disappeared from evolutionary tree?
Is it possible that they hide in that elusive moment of time when am changes to pm?

Why don't you just say you live on the Tropic of Capricorn - it's what Rocky is known for. ::)

It's 2,598 klms away from the Equator - which has no relevance to where you live.

The tip of Cape York is still 1,185 klm from the Equator.

Probably because I live at 23 degrees. 23°21'12.3''S to be more precise. Not 23.5°S.

The daylight hours barely change during the seasons, although there is the 3 hours difference between summer and winter solstice daylight hours. Still, the seasons are very different.

People in Hobart must go nuts during the summer and winter days.
