Biurnal is choosing to not be nocturnal or diurnal. It's just sleeping whenever your inner clock decides, resting when you're tired, waking when you feel refreshed, time is of no essence.

/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.
