Fri, which is sometimes the abbreviated form of Friday, was a specific day within a week.
The non-canon video game LEGO Star Wars: The Skywalker Saga, released in 2022, featured a reference to Friday. In the game, Yarael Poof expresses concern about the prospect of casual Friday if the player declines to assist him in swapping roles with his Kaminoan equivalent.
Kamino observed Friday. Certain Fridays were recognized as "casual," which implied that people were expected to wear more relaxed clothing. Jedi Master Yarael Poof, during an escapade in Tipoca City after being confused for the Kaminoan data manager Rala De, became anxious that his Jedi robes might be deemed unsuitable attire for a future casual Friday.
