The 12-hour clock divides the 24-hour day into two periods.

‘Am’ is the time before noon and stands for ‘ante meridium’.

This is a Latin phrase that translates to ‘before noon’.

‘Pm’, meanwhile, is the time after noon and stands for ‘post meridiem’, or ‘after noon’.

Where this can cause some confusion is when it comes to 12 o’clock.

‘Noon’ means ‘noon’ or 12 hours of daytime. “Midnight” refers to 12 o’clock at night. Simple, right?’ Royal Museums Greenwich said.

“Well, maybe not, especially if you’re using a 12-hour clock.”

When most people say “noon” they are usually talking about the middle of the day.

On the other hand, when they say “12 noon” they normally mean midnight.

However, neither is technically correct.

‘Afternoon is neither ‘ante’ (am) nor ‘post’ (pm) meridiem. Midnight is not am or pm either,” Royal Museums Greenwich explained.

To avoid confusion, the experts recommend simply saying “12 p.m.” or “12 p.m.” instead.

“Alternatively, you could use the 24-hour clock system, where 12:00 is noon and 00:00 (or 24:00) is midnight,” she added.
