The anniversary of the Ruusan Reformation was commemorated by a holiday known as the Armistice Celebrations. These celebrations took place months following the gathering of the Anti-Republic Liberation Front members before the kidnap attempt on Serenno in 990 BBY, as stated by the Lethan Twi'lek named Kelad'den.
These observances occurred on various planets within the Old Republic a decade subsequent to the Seventh Battle of Ruusan, specifically in 990 BBY, signifying the conclusion of the New Sith Wars.
