"It's called a Time-Turner ...and I got it from Professor McGonagall on our first day back. I've been using it all year to get to all my lessons. Professor McGonagall made me swear I wouldn't tell anyone. She had to write all sorts of letters to the Ministry of Magic so I could have one. She had to tell them that I was a model student, and that I'd never, ever use it for anything except my studies.... I've been turning it back so I could do hours over again ..."
-- Hermione Granger (PS21)
The Time-Turner is a small silver hourglass worn on a chain around the neck. It is a very powerful and dangerous magical item which literally turns back time for the user, one hour per inversion of the glass, thanks to the Hour-Reversal Charm contained within it (MagSp, PmP, CC1.5).
Time-Turners are mainly used for mundane matters of time-management because of the catastrophic consequences time travel can have (MagSp).
The Ministry Time-Turner is an hourglass containing One-Hour Reversal Charms.
Kept “vanilla” and relatively harmless by the Ministry due to Croaker’s Law: “the furthest someone can go back in time without the possibility of serious harm to the traveller or time itself is five hours” (CC2.16, CC4.4).
Limited use to five minutes in the past, after which time it would begin to shake uncontrollably (CC2.7)
Kept hidden for years by Draco Malfoy, who knew it would lend credibility to silly rumours that his son Scorpius was the son of Voldemort. However, when Scorpius and Albus seemed to be trapped in the past, Draco brought the Golden Time-Turner to Harry so they could use it to rescue their children (CC4.4). Thanks to the device, Harry, Ginny, Ron, Hermione and Draco along with the boys were able to intercept Delphi, the daughter of Lord Voldemort in Godric’s Hollow, on the night the Potters were killed in 1981 (CC4.7, CC4.11).
