October 3rd is recognized every year as Mean Girls Day, in homage to the popular 2004 movie “Mean Girls.” The significance of this date within the film comes from the moment when the main character, Cady, is asked by her love interest, Aaron, for the day’s date, and she responds, “It’s October 3rd.”

As time passed, fans worldwide began observing this day as an unofficial holiday, using it as an opportunity to reminisce about their favorite lines and reflect on the memorable role the film has in pop culture.

History of Mean Girls Day

October 3rd is celebrated every year as Mean Girls Day, paying homage to the 2004 movie ‘Mean Girls’ directed by Mark Waters with a star-studded cast including Lindsay Lohan, Rachel McAdams, Amanda Seyfried and Lacey Chabert.

The idea of Mean Girls Day began to circulate via social networking platforms around 2014, potentially in conjunction with the film’s tenth anniversary. This celebration evolved naturally among its fanbase and is not an officially sanctioned holiday.

The reason October 3rd is selected as Mean Girls Day centers around a specific dialogue in the movie. In a particular scene, Lindsay Lohan’s character, Cady Heron, narrates, “On October 3rd, he asked me what day it was.” Aaron Samuels, portrayed by Jonathan Bennett, inquires about the date, and she responds by saying, “It’s October 3rd.”

This seemingly ordinary dialogue became popular among fans and was further propelled by social networking sites. Fans began to designate October 3 as Mean Girls Day, creating traditions like quoting famous lines, wearing pink (inspired by another memorable quote from the movie “On Wednesdays, we wear pink”), among other film-related activities.

The movie cast has also shown enthusiasm for Mean Girls Day, often posting about it on their social media platforms. In 2017, several original cast members leveraged the day to fundraise for victims of the Las Vegas massacre.
