I'm playing with an otherwise earthlike world where I have handwaved away the visible sun and moon: anytime you look at a cloudless sky, you see stars, and only stars. How can the people of this world use the stars to tell time?
Thanks to Artifexian's videos on the subject, I'm already familiar with constructing lunar, solar, and lunisolar calendars. I'm interested in finding similar information for what a stars-only calendar might look like. Info on smaller-scale demarcation of days and hours would also be useful. I know that certain constellations in the zodiac correspond with certain months, and that one can tell the hour of the night by looking at the position of the Big Dipper, but both of these methods require cross-referencing with solar and lunar timekeeping. Could one tell time in this way using only the stars? (I'm willing to include "wandering stars" or visible planets.)
Note that the people of my world are very low-tech but reasonably intelligent. They are restricted to naked-eye observations.
