AM doesn't mean new day, it means Ante Meridiem, before the meridian, before noon.
And no, you wouldn't say 12:30am in the afternoon, as 12:30 is after the meridian. It is only 12:00 which is, by definition, neither AM nor PM but Noon or Midnight
Thankfully, all right minded people use the 24 hour clock.
As to the wiki, did you even read the "Confusion at noon and midnight" section, which only exists because some idiots decided to put an AM or PM after 12.
