HOUSTON, Texas (KTRK) -- July 13, or 7/13, marks a numerically coincidental day in Houston.When area codes first came to North America in 1947, Texas was designated for four sets of codes. Houston was assigned the digits 713.Of course, additional sets of numbers were given to the growing area, including 281 and 832.But the original always stays with us, and conveniently enough, the seventh month of the year has a 13th day. And, thus, Houston has 713 Day.While there's not really a historical concept of the day, Houstonians have marked July 13 as H-Town's day, celebrating the things and landmarks that gives Houston its identity.Here are some of the celebrations scheduled in the city for this year, according to the website 365 Things To Do in Houston There are also some ways you can mark 713 Day beyond these celebrations, including mural hunting inside the Loop and scarfing down breakfast tacos at any of these hot spots You can get a complete list of some Houston suggestions here
