Since home video games have been out for almost exactly 48 years now, I decided to do a "Cosmic Calendar" type thing, condensing the history of video games into a single hypothetical year. On this scale, 1 month = about 4 years.
To get the exact dates, go into Excel, put Jan. 1 in Cell A2, Jan. 2 in Cell A3, and click and drag until you get to Jan. 1 of the next year (A367). Use a non-leap year, so no Feb. 29. In cell B2, put 9/15/1972, in cell B3 put 11/2/1972, and click and drag until you reach cell B367, which should be 9/3/2020.
