biurnal (adj.)
/bye-UR-nuhl/

Sleeping in two distinct shifts within a 24-hour period — for example, 4 hours during the day and 4 at night — because one continuous sleep just isn’t your style. Not to be confused with “binaural,” which won’t fix your sleep schedule but might make you hear colors.

Origin:
From “bi-” (two) + “diurnal” (daily). Sounds sophisticated, but mostly means your circadian rhythm is running a split shift.
Example:
“You were texting me at 5 a.m. and again at noon. You good?”
“Yeah, I’m biurnal. Two sleeps, double the dreams.”
