Actually, on second thought, I can argue that it makes sense, but only if you rename 12 to 0, I.e. midnight is 0 o’clock. Similarly, recapping the year at the beginning of December makes sense if you rename December to Zerouary and make sure the year starts on Zerouary zeroth.
Probably the same reason that a.m. becomes p.m. at 12:00
Ah, so, pure unadulterated bullshit.

Because that’s when the timezone passes through the sun’s zenith?
Classic meridian bullshit
Am and pm means before midday and after midday in Latin.
After 11:59 you are after midday.
Before 12:00 you are before midday.
That explanation doesn’t make the concept any less ridiculous.
