12 AM IN THE GARDEN OF GOOD AND EVIL?

Something that bothers me, that doesn't seem to bother anyone else is the posting of times. I was taught to never use 12am and 12pm, but instead to use Noon and Midnight.  Surprisingly, when I wrote for Carnival Cruise Lines I got them to use those designations in their brochures. One could spend days deciding at which point 12 O'clock is am or pm, or AM or PM or A.M.or P.M. or a.m. or p.m. Noon and Midnight is so much easier. Even today if I ask otherwise intelligent people, they stumble over which is which. If I had my way, we would only use Noon and Midnight. But then, if I had my way, people would stop saying "the reason why" since the "why" is totally unnecessary.
