Meso meridiem

Published

I would like a way to express a time after 6 PM and before midnight following the AM and PM conventions.

  • AM (ante meridiem) 0000–1200
  • PM (post meridiem) 1200–2400

But what is in between? A sort of meso meridiem?

  • AM AM (ante meso ante meridiem) 0000–0600
  • PM AM (post meso ante meridiem) 0600–1200
  • AM PM (ante meso post meridiem) 1200–1800
  • PM PM (post meso post meridiem) 1800–2400

“I will see you in the PM PM”
