Houston Astros and Bun B drop special hat collection for 713 Day

HOUSTON, Texas (KTRK) -- It's that time of year again. Houston's unofficial holiday, 713 Day, has arrived to celebrate the first digits the Bayou City was assigned.

If you're not familiar with how Houston started off as the 713, when area codes first came to North America in 1947, Texas was designated for four sets of codes.

Houston received 713.

Of course, the area's growth has boomed since then and continues to do so, with the additional numbers of 281, 832 and 346 being assigned over the years.

The day is celebrated in July (the seventh month) on the 13th day, and there you have it, 713 Day is born.

Plus, the other codes just don't work with the calendar, right?

Events pop up all over town in honor of the day. Here are a few of the highlights, but if you know of one that should be added, let us know.

Bun B and Houston Astros drop limited-edition hat collection: Bun B hinted at it last week when he threw the first pitch at the Astros game. During the outing, the rapper wore a black hat with a "Trill OG" crest on the front and the Astros logo in gold on the side. In a recent photo on Instagram, Bun B is donning a different cap, while the three other headpieces, including that aforementioned black hat, are also in the frame. It appears you can finally get your hands on them. You can shop the collection and meet Bun B at the Union Station team store at Minute Maid Park starting at 2 p.m. If you can't make it early, the store closes fitting at 7:13 p.m. No online or phone orders will be available.

Along with the hat, fans can get the 713 Edition Box.
