The group idea is really interesting. It's probably really nice to be able to have a bit of fun with girls your own age like that.
Even though I an Atheist, I do like to keep one special day week for reflection and such. Although, I could never imagine life without coffee for one day let alone at all, I try not to spend money or work more than necessary on that day. (though I'm not sure about your beliefs about working. Are they the same or similar to Catholic beliefs on the 'day of rest'?)
It's good for the mind and body, even if it isn't for religious reasons
