ELI5: How to get a Moon encounter

This has to be a common question, but I can't find it through searching through posts. The launch azimuth wiki post in the sidebar may as well be Greek.

Since KSC is off-equatorial, and since the Moon is even more so, how do I determine what a good launch window is for a Moon-shot (or say a Mars-shot)?

Alternatively, is there a method for launching on any given time/day to align your craft for a Moon encounter?
