Did you know that the Alaska Territory was purchased and became property of the United States on October 18, 1867? Further, did you know for the residents of that Territory the date should have been October 7th? Yep, the day the U.S. took possession of the Alaska Territory two things happened to change the date. One, the residents calendar was changed from the Julian to the Gregorian calendar and Two, the International Dateline was moved! So, Alaska residents got to have Friday October 6th followed by Friday October 18th!
Isn't that interesting?
