I prefer to get in really early and get most of my work done then, so that I don't have to stay too late.

These days a typical day is like 6:30 - 16:00ish. Apart from Thursdays when I teach astronomy in the evening too, that's pretty tough.

It's super cliché, but you gotta find a job you enjoy so the long days don't feel so long.


EDIT: when I worked part-time though, I worked nights. Was a poor life decision, don't do night-shifts.
