When is International Tabletop Day?
International Tabletop Day has been hosted by Geek &amp; Sundry every year since 2013,* but the schedule has been somewhat inconsistent as to when it is. I had a hard time finding the dates, especially for the early ones, but here they are:


March 30, 2013
April 5, 2014
April 11, 2015
April 30, 2016
April 29, 2017
April 28, 2018


If the pattern for the last couple of years holds, then one would expect that in the future it will be held on the last Saturday in April.

* The logo for International TableTop Day says that it's "since 2012", but I cannot find any evidence that it was actually held in that year. @PatLudwig in the comments provides supporting evidence that 2013 was the first.
