JewelofYavindate

The Jewel of Yavin is set during Lando Calrissian's tenure as Baron Administrator of Cloud City and before the Galactic Empire's occupation of that settlement. "Lady Luck" — Star Wars Tales 3, which depicts Calrissian winning the title of Baron Administrator in a game of sabacc, is set a year after the Battle of Yavin, which corresponds to 1 ABY, according to The New Essential Chronology. Since the latter source also dates the occupation of Cloud City to 3 ABY, the events of The Jewel of Yavin must be set at some point between those two dates.
