The Peldor Festival or Gratitude Festival was a Bajoran tradition. The festival involving the burning of renewal scrolls and greeting others with "Peldor Joi". (DS9 episodes: "The Nagus", "Fascination", "Rapture", "Tears of the Prophets", ST - New Worlds, New Civilizations short story: "The Glories of the Hebitians") Quark used the days leading up to the Gratitude Festival in the early 2370s to convince patrons in debt to him to paint his bar for free.
