Deliberate mistake: When Jack fights the impostor, they are roughly the same height, but when the impostor is revealed to be Angelica, she is suddenly much shorter than him. (00:21:30 - 00:23:50)
Revealing mistake: When Jack Sparrow is chased in London, being on the carriage and looking back to his chasers, you can see the broad tire tracks of a modern vehicle in the mud. (00:16:55)
Continuity mistake: When the movie ends, Barbossa is given his hat with no feather. A frame later the feather appears. (02:04:55)
Suggested correction: These movies aren't set in a specific time.
Credit for the following goes to another member here, Super Grover, who actually answered a question about the dates the films are set a while ago. These dates are estimates. The intro of 'PotC: The Curse of the Black Pearl' takes place mid-1720s (roughly 1725), when Will and Elizabeth are around 11/12 yrs old. Then eight years later the duo are about 19-20 yrs old during the main part of 'The Curse of the Black Pearl', then around a year later are set to marry in 'PotC: Dead Man's Chest' followed by the consecutive 'At World's End', which take place around 1733 / 1734. The next movies 'PotC: On Stranger Tides' and 'Dead Men Tell No Tales' (after the intro) take place in the 1750s. Again, credit to Super Grover.

They're set in the 1700's. In "On Stranger Tides", King George wants Jack to find the Fountain of Youth before King Ferdinand, who reigned from 1746 - 1759.
