    What's the next end date after Dec 2020? (after it passes without incident)

    It seems to me that the Mayan calendar is associated with the cycle of Venus.
    December 21, 2012 / December 21, 2020 corresponding to an 8-year cycle.
    On December 21, 2012, we were under a perfect quincunx of retro Jupiter at 8 ° Gemini and Saturn 8 ° Scorpio and this December 21, 2020 under a perfect conjunction of Jupiter and Saturn 0 ° Aquarius, we set the counters to zero symbolically speaking?

    You may still be able to change the title to the current one, for example the Mayan Calendar 2012/2020

    ... it seems like the Mayan "Calendar(s)" were astronomical time-keeping pieces like almanacs rather than simple "calendar":

    Scientists solve mystery of how the Mayan calendar works

    We were thinking too small all along.

    The Mayan calendar's 819-day cycle has confounded scholars for decades, but new research shows how it matches up to planetary cycles over a 45-year span. That's a much broader view of the tricky calendar than anyone previously tried to take.

    In a study published in the journal Ancient Mesoamerica, two Tulane University scholars highlighted how researchers never could quite explain the 819-day count calendar until they broadened their view.
    "Although prior research has sought to show planetary connections for the 819-day count, its four-part, color-directional scheme is too short to fit well with the synodic periods of visible planets," the study authors write.

    "By increasing the calendar length to 20 periods of 819-days a pattern emerges in which the synodic periods of all the visible planets commensurate with station points in the larger 819-day calendar."

    That means the Mayans took a 45-year view of planetary alignment and coded it into a calendar that has left modern scholars scratching their heads in wonder.

    While ancient Mayan culture offered various calendar types, the one that baffled scholars the most was this 819-day calendar discovered in glyphic texts. Researchers have long believed this calendar was associated with planetary movements, especially the synodic periods — when a planet appears visually to return to the same location in the sky, as seen from Earth — of key planets. However, each planet moves quite differently and matching up multiple planets into an 819-day span didn't seem to make sense.

    But it does when you look at it over 16,380 days (roughly 45 years), not just 819 days. That's a total of 20 x 819-day timelines.

    Mercury was always the starting point for the tricky timeline because its synodic period — 117 days — matches nicely into 819. From there, though, we need to start extrapolating out the 819 number, and if you chart 20 cycles of 819 days, you can fit every key planet into the mix.

    And Mars may be the kicker for the overall length. With a 780-day synodic period, 21 periods match exactly to 16,380, or 20 cycles of 819 days. Venus needs seven periods to match five 819-day counts, Saturn has 13 periods to fit with six 819-day counts, and Jupiter 39 periods to hit 19 x 819-counts.
    "Rather than limit their focus to any one planet," the authors write,

    "the Maya astronomers who created the 819-day count envisioned it as a larger calendar system that could be used for predictions of all the visible planet's synod periods, as well as commensuration points with their cycles in the Tzolk'in and Calendar Round."
