=== Time-Turner ===
A '''Time-Turner''' may be used for short-term [[time travel]]. Hermione receives a Time-Turner from McGonagall in ''Prisoner of Azkaban'', enabling her to attend more than one class simultaneously. Hermione is ordered to keep it a secret from everyone, including Harry and Ron, although they notice the suspicious impossibility of her schedule and several bizarre disappearances and reappearances. Hermione reveals the secret to Harry and Ron near the end of the book, when she and Harry use the Time-Turner to save Sirius Black and [[Buckbeak]]. Strained by her heavy course load, she returns the device to McGonagall at the end of the novel. Hermione's Time-Turner resembles a gold hourglass pendant on a necklace.<ref name="PA21">{{HPref|book=3|chapter=21}}</ref>

Time-Turners are a significant point device in ''Cursed Child'', where it is revealed that a principle known as Croaker's Law restricts all legal Time-Turners to travelling a maximum of five hours into the past. It is widely rumoured that Draco Malfoy's son Scorpius is the son of Lord Voldemort and that Scorpius's mother used a Time-Turner to make this possible. An illegal Time-Turner capable of travelling back years is confiscated from a Dark wizard by the Ministry of Magic (although official word remains that all Time-Turners are destroyed) and is later stolen by Albus Potter and Scorpius Malfoy, who intend to travel back in time to prevent the death of Cedric Diggory. Unfortunately, they quickly discover the Time-Turner is a cheaply made prototype that only takes them back for five minutes before forcibly returning them to the present. After accidentally creating (and then undoing) an [[Alternate history|alternate reality]] where Voldemort survived and took over the world, Albus and Scorpius resolve to destroy the Time-Turner, but are forced into another time trip by the story's villain and are left trapped in the past when the Time-Turner is destroyed. Back in the present, Draco reveals he possesses a professionally made Time-Turner (bound by neither Croaker's Law nor the five-minute flaw) - he never admitted its existence for fear it would lend credence to the rumours surrounding his son and never used it (despite being tempted by the possibility of seeing his dead wife alive again). When Albus and Scorpius are able to send a message to their parents, Draco's Time-Turner is used to rescue the boys.
