No work today "because"

[Abecedarian]

"Remember that there's no work today because it's Sunday."

I filled the blank with "because" however I am trying to understand why it is (or would be?) wrong to say:
"Remember that there's no work today for it's Sunday."

I ask this because sometimes we use "for" in similar circumstances.

"The solution is to not forget the traffic rules, for it is punishable if you violate them"

Maybe that is a wrong example but I hope you understand what my doubt is?

Thank you

oh maybe
"Remember that there's no work today for it's a Sunday."

might make sense?

"Remember that there's no work today because it's Sunday."

"Remember that there's no work today for it is Sunday."
because and for

Yes, they're pretty much the same but "for" is used mostly in written formal context.
