A Day of Days represented a tradition among the Chandrilan people, characterized by the exchange of gifts. During the year 5 BBY, Imperial Senator Mon Mothma made an appearance at the Galactic Antiquities and Objects of Interest, ostensibly to procure a present for her husband, Perrin Fertha, in observance of his Day of Days; however, her true intention was to confer with Luthen Rael concerning their shared rebel activities.
