Proemium.

The reckoning of the day in Cebuano had always been based on the events in the sky, as the rest of the world did before the advent of dials and clocks. Henceforth, see the 00:00 xx as approximations only and not actual days.

Adlaw. The sun. The day. 

Kaadlawun. Refers to the recession of the current day and before the beginning of the next day.

The divisions of a day. 

Kabontagun. Refers to the recession of the night and before the buntag which is the full morning after the sunrise. This is the dawn. This overlaps with kaadlawun, as both begin at the same time. This is also referred to as bolobuntag. It is therefore said of this time kabuntagun na, bolobuntag na, or nagakaadlaw na, nagakaaga na.
