Happy Day Of Deliverance!

Pioneer Day (also archaically called the Day of Deliverance)[1] is an official holiday celebrated on July 24 in the U.S. state of Utah,[2] with some celebrations in regions of surrounding states originally settled by Mormon pioneers.[3][4] It commemorates the entry of Brigham Young and the first group of Mormon pioneers into the Salt Lake Valley on July 24, 1847,[5] where the Latter-day Saints settled after being forced from Nauvoo, Illinois and other locations in the eastern United States.[6] Parades, fireworks, rodeos, and other festivities help commemorate the event.
