The actual reason the date was set in 1968 was because of Martin Luther King's birthday being celebrated in January. Prior to that, both Feb 12 and Feb 22 were holidays. Feb 12 for Lincoln and Feb 22 for Washington. In order to do away with one of the days, they combined the two and came up with President's day. It was all done because of the addition of MLK day in January.
