Finally binged this. Curious about what the title means. Is it a proverb or something?

Beware the ideas of March is a references to the Shakespeare play “Julius Cesar” about his assassination. Someone said it to him foreshadowing the betrayal of the Senate and his death.

I'm aware of the Ides of March! I was asking about the alternate title- Beware of the Full Moon in March. Is it also a reference to the ides I wonder... Anyway, ty!
