Is there a word to encompass the two states of a day: AM and PM, morning and afternoon?

Question

A single word which sums up the option of AM/PM or morning/afternoon.

Depending on the context, I've seen the following used to good effect: "day or night", "on that date", "during that 24-hour period". — Karasinsky, Jul 03 '15 at 14:18
