Oklahoma Day is an annual state holiday celebrated on April 22 in the United States, commemorating the date in 1889 when the Oklahoma region became open to European settlement. The celebrations are primarily centered in Guthrie, which is about 80 miles from the starting line of the land rush. Known as Oklahoma 89ers Day, the event features reenactments of the land rush, which were first performed by the original participants in 1915. Parades and festivities take place in various areas of Oklahoma to mark the occasion. The holiday honors the legacy of the "89ers," who claimed land during the initial settlement period.
