First Post
Hey, everybody. My first post here. 
A quick question for all of you GMs: when you're creating a homebrew campaign world do you usually use a real-world calender or do you go all out and create your own calender? And if you do create your own calender how far do you go? New days of the week? A full list of holidays? History to each holiday?
I'm just curious, because I usually end up going somewhere in between. I keep seven day weeks with familiar days, but usually end up making new months for flavor. Just so things don't get too confusing for players I keep 12 months and don't mind if my players refer to the months by their real-world names since I keep the same number of days per month (ie, the first month of the year still has 31 days).
What about the rest of you?
