Which ancient South American civilisation had a calendar that ends on 23 December 2011?

Answer 1

None, but you're thinking of the Mayans, whose calendar "ends" on December 21, 2012. However, 2012 is simply when the current baktun of the Mayan calendar ends. A baktun is a 400 year period, and we are in the twelfth baktun. It is true that the Mayan calendar effectively ends on December 21, 2012, but only because for whatever reason the Mayans didn't extend the calendar beyond the end of the twelfth baktun. Maybe the Mayans would have extended the calendar centuries ago if their civilization hadn't collapsed.

Answer 2

Mayan, however the date isn't 2011, it's 2012 and it's not the end of the calendar, it's the end of 'The Long Count'.

Logically, the first date in the Long Count should be 0.0.0.0.0, but as the baktun (the first component) are numbered from 1 to 13 rather than 0 to 12, this first date is actually written 13.0.0.0.0.

The authorities disagree on what 13.0.0.0.0 corresponds to in our calendar. I have come across three possible equivalences:

13.0.0.0.0 = 8 Sep 3114 BC (Julian) = 13 Aug 3114 BC (Gregorian)
13.0.0.0.0 = 6 Sep 3114 BC (Julian) = 11 Aug 3114 BC (Gregorian)
13.0.0.0.0 = 11 Nov 3374 BC (Julian) = 15 Oct 3374 BC (Gregorian)

Assuming one of the first two equivalences, the Long Count will again reach 13.0.0.0.0 on 21 or 23 December AD 2012 - a not too distant future.

The date 13.0.0.0.0 may have been the Mayas' idea of the date of the creation of the world.

Although they are not part of the Long Count, the Mayas had names for larger time spans. The following names are sometimes quoted, although they are not ancient Maya terms: 1 pictun = 20 baktun = 2,880,000 days = approx. 7885 years
1 calabtun = 20 pictun = 57,600,000 days = approx. 158,000 years
1 kinchiltun = 20 calabtun = 1,152,000,000 days = approx. 3 million years
1 alautun = 20 kinchiltun = 23,040,000,000 days = approx. 63 million years

The alautun is probably the longest named period in any calendar.

Answer 3

The Mayan calendar is the main marvelous, because it includes an entire description of the magic cycles, which incorporates this modern-day crossing of the edge. The Mayan calendar exchange into created contained in the 365 days 3372 BC (employing the Christian calendar), only on the top of the final cycle. The Mayans defined the cycles as "worlds", and reported that for the period of standard terms specific existence varieties made the transition from one international to the subsequent. The calendar, written over 5,000 years in the past, expected the impressive day the edge point could be exceeded. If we convert the Mayan dates to the present Christian calendar, it properly states that the edge could be exceeded on December 24, 2011. Atlantis sank on August 12, 3113 BC, for that reason marking the top of the Fourth international and the start of the 5th. The 6th international will initiate on December 12, 2011 advert, and could end, in accordance to the Mayan calendar, on April 4, 7137 advert.
