When to say midnight on the 10th of December?
By convention, “midnight on the 10th of December” should refer to the end of the day of December 10, the instant before December 11 starts.

What’s the difference between midnight and 12 : 00pm?
If you want to be pedantic, 12:00:00pm is not a valid time. The PM part means “post meridian” which 12:00:00 is not. It is merely convention that 12:00:00 (which follows 11:59:59am and is followed by 12:00:01pm) is labelled 12:00:00pm. The point remains that midnight touches two dates and is technically part of the start of the day not the end.
