The year starts on any one of the seven days and then it's either leap year or not. Leap year is what moves the rotation making it take longer for the days to come back around.

Sounds like that makes sense. Actually it makes perfect sense, I believe you are correct.
Also, just a bit of additional information, a leap year doesn't occur EVERY four years. One Earth year is just under 365.25 days long, it's actually 365.2425 days long.
So...every few thousand years...when we SHOULD have a Leap Year, we won't to make up for this decimal issue.
This is by the Gregorian Calendar, there are other variations in other calendars. You can check it out in Wikipedia if you're really interested. It's kind of confusing.

Well, I've never actually looked it up, but yes, I would believe you are right.
7 variations would come from years that start on Sunday, Monday, Tuesday, Wednesday, Thursday, Friday or Saturday, that do NOT have leap year.
And the other 7 variation would come from years that start on , Monday, Tuesday, Wednesday, Thursday, Friday or Saturday, that DO have a leap year, giving those years 366 days.

You are correct. It is possible to make a perpetual calendar, in which a scale of months is aligned with a scale of years to open an aperture which gives the calendar for that month.
