Normally planets in the night sky appear to go from west to east but during a retrograde period they almost look to go in reverse. This switch is due to the position of the planets to the sun and not an actual change in movement. But according to some when Mercury goes into Retrograde it can affect your day to day life in many ways.

The Farmer's Almanac says that when Mercury is in Retrograde communication, travel, contracts, automobiles and more can be impacted. There's also those who believe more people feel sick or not themselves during this period. Currently Mercury is in Retrograde until December 23rd and then in 2018 it'll be in retrograde March 23 to April 15, Jul 26 to August 19 and then again November 17 to December 6.

Experts say that during this time instead of hiding in a hole to avoid conflicts related to the phenomenon you should reflect on what's really important and live life in a simpler fashion. Or just next time you're late to work you can blame it on Mercury...
