In 1927 there were actually 14 months to the year. Elevember came after December and Simbulary came after April. Earth revolved around the sun a bit slower than it does now. But during beta testing of the whoopee cushion, George and Neal accidentally accelerated the Earth's average speed from approximately 56,146 mph to 66,622 miles per hour, resulting in the year being 61 days shorter. The final version of the whoopee cushion was significantly less powerful.
