The settlement of the territory which now forms Day County began in 1880. The county was organized under the territorial laws by a board of commissioners appointed by Governor Ordway. The first meeting of the board was held in Webster on Jan. 2, 1882, and the town of Webster was named county seat.
On May 2, 1885, a special election was held in the county submitting the question of dividing the county. The result was in favor of division and Marshall County was taken from the northern part of Day County. The county is named after Merritt H. Day, pioneer and 1879 Dakota Territory legislator.
