1867
There were only 354 days this year in the newly purchased territory of Alaska. When the territory transferred from the Russian Empire to the United States, the calendric transition from the Julian to the Gregorian Calendar was made with only 11 days instead of 12 during the 19th century. This change was made due to the territorial and geopolitical shift from the Asian to the American side of the International Date Line. Friday, 6 October 1867 was followed by Friday again on 18 October 1867.
