*Note: All Mayan Calendar dates on this website are from the exact proven accurate calendar of the Guatemala-highlands Maya 'count of days' used today by the oldest Mayan communities. The other calendar 'count of days' known as the Yucatan-lowlands Mayan calendar count, used by the-late DR. JOSÉ ARGÙELLES, is miscounted by 57 days as of 2020. The Yucatan-lowlands count of days miscount began hundreds of years ago and is no longer aligned with the rising and setting cycles of the planet Venus, which is what the Mayan Calendar is suoosed to be based upon. This split can be traced back into the 1500's with the arrival of the "divide & conquer" Spanish army in 1519.
