Is there a higher meaning to Tuesdays... [I Am Curious]

Taco Tuesday?

Yes. Tuesday is derived from the old English Tiwesdæg which can be further translated to "Tyr's Day." A day for the worship of the Norse God Tyr.

It's associated with Mars.

Named after Tyr

Umm... Psychologically it's "yay almost half way through the week" and "boo, almost only half way through the week" It's a butt day. ┬┴┬┴┤•ᴥ •ʔ/
