It’s a good question for every single SW movie (and other) I guess:

TPM: more than a week (3 days on Tatooine, a few days on Coruscant, and last scene a few days after Naboo is taken back);
AOTC: more that a week, less than two (2 days on Coruscant; 3 days to travel to Naboo and to leave to Tatooine; 2 days on Tatooine and to go to Geonosis; 1 day on Geonosis; and finally the ending shot that can occur a few days after the battle of Geonosis);
TCW: first series: 3 years; second series: 2 years;
ROTS: tricky one. Padmé is already pregnant, Anakin has not showed up in a few months, and the babies are delivered at the end (with the ending montage which is Wibbly Wobbly Timey Wimey stuff). I would say a few weeks, maybe a complete month or more;
Rebels: 5 years
ANH: around a week, yeah;
TSWHS: 1 day: Life Day !
ESB: again, tricky one. So much is going on in this one, I would say more than a week, two weeks top (2 days on Hoth… and then it’s almost impossible to guess);
ROTJ: 3 days on Tatooine, 1 day on Dagobah, 1 day with the fleet, 2 days on Endor. A complete week ?
TFA: Poe captured on the first night; BB8 travels to Rey the next day and then spends the night with her (lucky bastard some might say); they take off from Jaku the next day and meet Han; it may take a day to meet Maz; First Order comes, Rey is captured, Rey escapes, they get back to the Reistance base… well, another full day ? Rey goes to the ancient Jedi Temple the next day I guess. 5 days ?
