Changing the calendar would be impractical, expensive, confusing, and ridiculous. There's no point in it. I don't give a shit that the way we date the year is a religious thing, it's a simple system that we all basically understand so let's just leave it at that.
My only little issue with the calendar is the order of the months. When September, October, November and December became the 9th, 10th, 11th and 12th months, they should have changed the names, because it just bugs me that the names suggest they should be the 7th, 8th, 9th, and 10th months. But that doesn't matter either.
