National Texas Day is observed worldwide every February 1, celebrating the unique history, culture, and heritage of Texas, the second largest U.S. state by both population and area. This day was established by National Day Calendar as part of its National State Days project, which began in 2017. Texas, known as the Lone Star State, has a rich history that includes its time as an independent republic before joining the United States as the 28th state on December 29, 1845. The name "Texas" is derived from a Caddo word meaning "friend," reflecting the region's Indigenous roots. Celebrations on this day do not coincide with Texas Independence Day, which is celebrated on March 2. National Texas Day serves to honor the spirit of the state and its contributions to the nation.
