Whether any earlier attempt was made to adjust the civil to the solar or Sothic year in order to restore the festivals to their proper places in the seasons temporarily or otherwise, is a question of great importance for chronology, but at present it remains unanswered.

From Project Gutenberg

Besides this solar year they had a sideral or sothic year, composed of 365 days and 6 hours, which corresponds exactly to the Mayas sacred year, that Landa tells us was also composed of 365 days and 6 hours; which they represented in the gnomon of Mayapan by the line that joins the centers of the stela that forms it.
