  • Terms 12 a.m. and 12 p.m. cause confusion and should not be used as neither the "12 am" nor the "12 pm" designation is technically correct.
  • It advisable to use 12 noon and 12 midnight where clarity is required.
  • To avoid ambiguity, airlines, railroads, and insurance companies use 12:01am for an event beginning the day, 11:59pm for ending it.
