Leap years!
Everyone loves leap years! Having that extra day in a year means you have an additional 24 hours to do absolutely nothing! Or you could try and trick a huge corporation by taking advantage of their one-month-long free trial, as Netflix once offered.
By signing up on January 29th, Netflix supposedly couldn’t cancel your free membership until the soonest leap year. This sounds pretty ingenious, but we think Netflix calculated a month in 30 or 31 days, not on the same date the following month. Sadly, Netflix doesn’t offer free one-month trials anymore, probably because so many people followed this person’s advice. Or maybe not.
