The Gratitude Festival is an annual Bajorancelebration of great importance to the Bajoran people. Also known as the Peldor Festival, it dates back as far back as 17600 BC.
The traditional greeting during the festival is "Peldor joi". Bateret leaves are traditionally burned, and participants write their problems on renewal scrolls which are then burned so that their troubles symbolically turn to ashes.
The logo seen on banners and flags during DS9: "Fascination" advertising the Festival incorporated parts of the logo seen on the uniforms of the medical personnel on Tantalus V and Elba II, namely the sun and the characteristic hand.
