Afternoon, Evening, Night

[DJGM]

You wrote that at 5.38 in the morning? I'd call that the middle of the night!

No, the middle of the night is halfway between 21:00 and 00:00, which 22:30.

Far as I'm concerned:

06:00 - 09:00 - early morning
09:00 - 12:00 - morning
12:00 - 15:00 - early afternoon
15:00 - 18:00 - late afternoon
18:00 - 22:00 - evening
23:00 - 06:00 - night time

06:00 - 09:00 is not early morning, it is mid to late morning. 00:00 - 06:00 is early morning.
As far as I'm concerned, whenever it's "am" it's morning, not night, or middle of the night.

LBC News 1152 in London has just renamed its drivetime
show "The Evening Report" which to my mind sounds a
bit odd for a show that runs 4-7pm

It's not so bad at this time of year but come June, it
certainly won't feel like the evening at 4.30pm

It is followed by the Nightly News at 7pm

Well, that's just dumb. Evening does not start until 18:00, and night-time starts at 21:00.

The LBC 7pm News bulletin should be renamed "Evening News" for clarity and correctness.

But for example I would say 'I didn't get to sleep until 1 o clock last night', not this morning.

I'd say "1AM last night."

For me,

0100 - 1159 Morning
1200 - 1659 Afternoon
1700 - 2259 Evening
2300 - 0059 Night

Last night, whatever time, is the dark period before I end up in bed. The only exception to this is when I don't end up in bed, but lets not confuse things.
