well even if theye did account for it, Ceasar doubled the smount of leap years factored into their count, so their count woudl still be off and the world woudl have still already ended

Yea, on further reading on it, it seems that the mayans 'knew' about the issue, and disregarded it as irrelevant. I think they had it all worked out, that each season would happen 'twice' on every day, in the 365 day calander.
And Its funny, in a sci-fi point of view, that all colonies would use a '365 day calander' as homage to earth, but always neglect to mention leap year. They tend to make it as a 'galactic standard' date/time system, and then would use there own 'local time' and convert accordingly. And local time? Not just date wise, but time varies by something like 15 minutes every 100 miles? (something like that at least) So to put it in einstien terms.
Time is Relative. :P
But as towards the 'mayan' thing, I recall something about a 'month of lost days', but apparently thats probably an unoficial thing that the mayan leaders 'possibly' did, and its highly skeptical whether or not they did it to 'set' the season 'correctly'. Course its not that hard on there calander either, to simply move the season 'forward' from an agricultural perspective, every 4 years. :P
But yea, they could have a 'month' to make up leap year, every 120 years to account for it, and by then, the seasons would have been 'off' by a month. Winter in July for instance, or summer in october.
