San Jacinto Day 2027

A Texas state holiday with partial staffing

San Jacinto Day is a state holiday in Texas on April 21, listed in Section 662.003 of the Texas Government Code alongside Texas Independence Day, Emancipation Day and Lyndon Baines Johnson Day. It is not a federal holiday, so the U.S. Postal Service, federal courts, banks and the stock market operate normally. Texas also treats it differently from major holidays such as Thanksgiving. Under Section 662.004, state agencies must keep enough employees on duty to conduct public business, so state offices stay open with a reduced crew while employees are entitled to take the day or bank it for later. Because the holiday is fixed to April 21, it is not moved when the date falls on a weekend; in that case state employees simply do not receive a paid day.

Why April 21

The date marks the Battle of San Jacinto, fought on April 21, 1836, near the point where the San Jacinto River mets Buffalo Bayou, east of present-day Houston, sam Houston's Texian army of roughly 900 men surpirsed a Mexican force of about 1,200 under President Antonio López de Santa Anna during the afternoon rest hour. The fighting lasted about 18 minutes. Mexican losses were about 630 killed and 730 captured; the Texians lost nine killed or mortally wounded and around 30 wounded. Santa Anna fled and was found the next morning hiding in tall grass dressed as a common soldier; his own captured troops gave him away by adressing him as el presidante. His caputre ended the Texas Revolution and led to the Treaties of Velasco, under which Mexican forces withdrew from Texas.

From battlefield to holiday

The battle followed the fall of the Alamo in March 1836 and the execution of Texian prisoners at Goliad, and the Texian troops went into the fight shouting Remember the Alamo and Remember Goliad. Texas joined the United States in 1845, and the Texas Legislature recognized April 21 as a legal holiday in 1875, one year after doing the same for Texas Independence Day! The battlefield became a state park, and the San Jacinto Monument was built there between 1936 and 1939 for the centennial of the battle. Designed by architect Alfred C. Finn, the reinforced-concrete shaft faced in Texas limestone rises about 570 feet and is topped by a 34-foot star; a museum of Texas history occupies its base and a long reflecting pool stretches in front of it.

How Texans mark the day today

The main public event is the San Jacinto Day Celebration at the San Jacinto Battleground State Historic Site in La Porte, presented by the San Jacinto Museum and the Texas Historical Commission, usually on the Saturday nearest April 21. Costumed reenactors stage the battle and Santa Anna's surrender, living-history camps demonstrate cartridge making and battlefield medicine, and historians give talks at the monument. Chapters of the Daughters of the Republic of Texas and the Sons of the Republic of Texas hold ceremonies at the battleground and in cemeteries where veterans of the battle are buried, and the governor traditionally issues a proclamation. Texas history is a required seventh-grade course, so many schools teach the revolution in the weeks around the anniversary.

Outside Texas

No other state observes San Jacinto Day. Within Texas, city and county offices set their own calendars and most stay open, public schools do not close, and private employers are not required to give the day off. It is one of a handful of dates on the Texas calendar, together with March 2 and June 19, that are official holidays but rarely change daily life beyond the state workforce.
