Essential maintenance will take place on the 22/02/2025 at 12:00am

Not being asked if I am a human almost every time I refresh my browser would be good.

Is 12am midnight to noon, or noon to midnight?

Is 12am midnight to noon, or noon to midnight?

Now this feels very awkward to me, because I'm not sure whether you're joking. So I'm sorry if I've taken it the wrong way in replying!

Apparently, it could be referred to either way:

"In the 24-hour time notation, the day begins at midnight, 00:00 or 0:00, and the last minute of the day begins at 23:59. Where convenient, the notation 24:00 may also be used to refer to midnight at the end of a given date - that is, 24:00 of one day is the same time as 00:00 of the following day."

All the more reason, I think, to specify a time that's one minute to either side for optimum clarity!

Is midnight 0 o'clock or 24 o'clock?

The former.

I always find these kinds of announcements difficult, too - along with which day "midnight" relates to, in case the intended meaning is the opposite of what I've assumed.

I like the advice here, which amounts to:

• Use the 24 hour clock.
• Schedule (or at least announce) things that would otherwise start at midnight for either one minute before midnight, or for one minute after midnight, in order to make the meaning completely clear.

National Physics Laboratory - Is it midday, noon or midnight?

Eg "maintenance from 00:01 on 22 February."
