Example: Wednesday ends at 11:59 pm and Thursday starts at 12 am? Why not have it end and start when the sun goes down and comes up?

Sunrise and sunset varies with the time of the year.

If it ends when the sun goes down, and starts when it comes up, then what do you do about the bit in between (the nightime), do we just ignore that bit?
As for why it ends/starts at midnight instead of midday, thats because I guess they decided it would be more simple to have the change of day happen at night when nobody it awake to be confused by it.

because, there always needs to be 24 hours in one day and the photoperiod changes throughout the year. at 12:00 noon, the sun is directly overhead. sounds like a reasonable reference point to me.
more or less.

i would say that because mid-day is the time at which the sun is at its highest in the sky then the day must start and end at equal times either side of mid-day
in other words the day starts at the mid point of the 24 hrs preceeding mid-day and ends at the mid point of the 24 hrs following mid-day

interesting...my days begin when I wake in the morning. do you accept that they begin at midnight because someone told you that was how it works, or did you decide on your own that this was the case?
