National Utah Day is observed worldwide every May 31 to recognize Utah as the 45th state to join the United States. This unofficial holiday was established by National Day Calendar and celebrates Utah's rich history and cultural significance. The state's nickname, the Beehive State, symbolizes industriousness and cooperation, chosen by Mormon pioneers who settled the region. The name Utah is derived from the Ute tribe, meaning "people of the mountains." The first American settlers arrived in the 1840s during the Mormon Exodus, led by Brigham Young, who reached the Salt Lake Valley in July 1847. The Utah Territory was formally organized in 1850 and became a state on January 4, 1896. National Utah Day is part of the National State Days project, which celebrates each state's history and culture in the order they joined the Union.
