Does The Mayan Calendar Says World Will End This Weekend?

It was fun while it lasted. According to a reader of the Mayan calendar, the world will come to an end sometime this week...possibly. The original prediction was December 21st, 2012. Clearly, we survived that.  A conspiracy theory on social media says the calendar was misread and the actual doomsday prediction is 8 years off.  The date of total destruction is June 21, 2020. That is this coming Sunday. Of course, this is coming from a conspiracy theorist who deleted the tweet that showed the calculations. Take it for what it is worth. With 2020 going how it is so far, would you be surprised?
