Go Skateboarding Day (GSD) is an official annual holiday conceived by the International Association of Skateboard Companies (IASC) to promote skateboarding. The holiday was started in California by Don Brown and is held on June 21 due to the fact that the day is the longest day of summer.



The holiday was conceived in 2004 by the International Association of Skateboard Companies (IASC) to help make skateboarding more accessible to the world through various events held in major cities around the world. In 2006, more than 350 events took place in 32 countries around the world, and, the following year, the IASC received Special Congressional Recognition from US Congresswoman Loretta Sanchez for its work in promoting the sport of skateboarding and encouraging young people to get outside and enjoy the sport.

This holiday is celebrated by millions of skaters around the world. On July 14, 2002 when New Yorkers Kerel «Srikala» Roach and Bryan Chin organized the first All City Skate Jam and circulated flyers for a day-long gathering of skaters from all walks of life. The day was a celebration that gained attention from other pros and larger businesses, including the International Association of Skateboard Companies, which, a year later, christened June 21 Go Skateboarding Day by 5boro Skateboards founder/owner, Steve Rodriguez. Now GSD accrues thousands of participants in each year all over the world. GSD NYC is considered one of the largest single gatherings of skateboarders in the world and is now considered an official holiday.
