Hello Barrie (Mortimer),

Hello Barrie (Mortimer),

I agree that the terms 12am and 12pm does cause confusion, and that neither is technically correct - though, personally, I have always taken it, that 12am is midnight, and 12pm is afternoon.

The 12-hour clock is causing worldwide problems, and to avoid any ambiguity, airlines, railroads, and insurance companies use 12:01am for an event beginning the day, 11:59pm for ending it.

Barrie, I’m glad that you brought this up, as I had never thought of it before; so, in future, I will try to avoid posting at noon or midnight.

Cheers,
Barry.
