One of the most important days on the geek calendar is upon us: International Batman Day on Saturday, Sept. 17.

The annual event includes the "Road to Batman Day" digital sale that goes through Monday, Sept. 19. Books will be $5.99 and periodicals will be discounted 75 percent in honor of the holiday. On Batman Day, Batman Vol. 7: Endgame and Batman Adventures Vol. 1 will each be on sale for $3.99. 

Batman Day Activity Kit is free for the downloading this year. It boasts activities and coloring pages for your small Batman fan. Another freebie? Fans can get a copy of Batman #1 from "DC Rebirth" from participating retailers, libraries and schools.

Batman Day was declared in honor of the 75th anniversary in 2014. It has grown each year, with events all over the globe. 

Each year comes with something special.

This year gets a boost from the announcement of animated feature film Batman: Return of the Caped Crusaders, which will be released on digital HD on Oct. 11 and DVD and Blu-ray on Nov. 1. The film will have three showings for one night only at theaters on Oct. 10. Originals Adam West and Burt Ward will return to voice Batman and Robin in the animated movie about the fight for Gotham against the combined talents of Catwoman (Julie Newmar), Penguin, the Joker and Riddler.

There are many other events to Batarang to right here in Dallas. 

Along with the libraries, schools and comics shops, even Pottery Barn Kids on Knox Street and Six Flags in Arlington will distribute free copies of Batman #1. Barnes & Noble is also participating. If push comes to shove -- they run out or your got up and go has gotten up and went without you -- just find a movie or two featuring our Caped Crusader and settle in.

But some shops are in a celebratory moods, such as Red Pegasus Comics, 208 W. 8th St., Dallas. They will have the free comics, a Gotham selfie station and Batman buttons. And things kick off at noon at Generation X Games & Comics, 3504 Harwood Road, Bedford.  There are many more; find a place to do the Bat-Tusi on the DC Comics blog.
