So I sometimes do random math when i can’t sleep and I just calculated how long it would have taken Lucius Malfoy and the death eaters to go back two years (since during evil plans they say that is the day after hp kills voldy) in avps
So I was going off the assumption that since Starkid used the book 3 time turner (the one with the hour glass), that it goes back the same amount of time: 15 minutes per press of the side button.
Okay so the death eaters want to go back to before hp’s first year. There are 8760 hours in a year. You multiply that by two to find the number of hours in 2 years: 17520 hours. Then you multiply that by four to find the number of 15 minute time periods in two years: 70080. That is also the number of times that Lucius needs to press the button on the time turner. Let’s say that Lucius takes his sweet time and presses the button 1 time per second. You use this info and convert seconds into days (for the easiest way to read it):
Lucius needs to press the button for 48.666666 (repeating) days straight; so picture this:
The death eaters finish their fab musical number and they’re all ready for Lucy to take em back, but they have to sit there with their hands resting on him for almost 7 weeks.
