Gryffindor Pride Day is celebrated annually on March 22 to honor the Gryffindor house from the "Harry Potter" series. Gryffindor is known for valuing courage and determination, and it is famously associated with the character Harry Potter. The house was founded by Godric Gryffindor, one of the four founders of Hogwarts School of Witchcraft and Wizardry, which also includes Hufflepuff, Ravenclaw, and Slytherin. The name "Gryffindor" derives from "Gryffin," symbolizing a half-lion, and "D’or," meaning made of gold, reflecting the house's colors. Notable figures from Gryffindor include Albus Dumbledore and James Potter. The day encourages fans to celebrate their love for Gryffindor through various activities, though specific customs are not detailed in the source.
