Aubrey Plaza reunited with her Parks and Recreation costars to celebrate the 8th anniversary of Galentine's Day, and she documented the memorable get-together with a photo.

Reunion

Parks and Recreation may be over, but the friendship that Plaza developed with her female costars lives on. The actress recently got together with her gal pals from the NBC series to reminisce about fun times and, most importantly, celebrate the best day of the year — Galentine's Day. The actress shared a photo with her former costars Rashida Jones, Amy Poehler, and Kathryn Hahn on her Instagram.

"Happy happy galentine's day. These women keep me alive," Plaza captioned the photo along with two heart emojis. The Legion star did not share any other details about the reunion, but it is clear from the grin on their faces that they had a great time.

Galentine's Day Origin

Parks and Recreation fans may be familiar with Galentine's Day. Women from the fictional city of Pawnee, where the NBC series is set, celebrate it a day before Valentine's Day, on Feb. 13. It is a time where they ditch their significant others and meet up with their girlfriends for some fun and laughter. It is a day to honor women friendships.

Galentine's Day was first introduced in season 2 episode 16 of the series. Poehler's Leslie Knope in Parks and Recreation describe the day as a time where she and her lady friends meet up for breakfast to celebrate being ladies.

"Every Feb. 13th, my lady friends and I leave our husbands and our boyfriends at home and we just come and kick it breakfast-style. Ladies celebrating ladies. It's like Lilith Fair, minus the angst," Knope explains in an episode of Parks and Recreation.

Influence

Galentine's Day has turned into a real-life celebration even after Parks and Recreation ended its seven-season run in 2015. Women from across the United States still get together on Feb. 13. Sloan Longway, a museum and planetarium in Michigan, celebrated its third Galentine's Day on Feb. 9. Olivia Kushuba, the special events manager, said patrons celebrated with karaoke, a photo booth, and various shopping opportunities.

Cure Coffeehouse also celebrates Galentine's Day. 20-year-old food blogger Rachel Heffington has attended the celebration twice where she recalled just having fun with her various friends and sisters.

"It was so supportive and instead of women comparing each other, we were just all there together, having fun, celebrating our friendship," Heffington said.
