The day's dial

Studying 8 hours a day: the real math.

Eight hours at the desk aren't eight hours of work. Pick when you start and how many hours you want to actually do: the dial lines up blocks and breaks and tells you when you'll finish.

Your blocks, one by one.

Every block starts on a quarter hour, like the sessions in the app. Today's and the next few days' can be booked from here: at that time you work on a video call with whoever booked the same time.

    What the math doesn't say.

    The dial counts minutes, not effort. The first hours usually go by easily, the last ones less so, and an eight-hour day repeated every day is a different thing from a single day. That's why it's worth starting from the number you can keep up for a week, not the one that sounds good.

    Many people start at the time they said they would when someone is waiting for them at that exact time. The first block decides the rest: if you do it with another person, you don't push it back half an hour.

    Frequently asked questions

    Is it possible to study 8 hours a day?

    Eight hours of real work, with breaks, take up more than ten hours of the day: with 50-minute blocks and 10-minute breaks, plus a long break, starting at 9 means finishing after 7 pm. The dial on this page does the math with your own times. Many people count the hours spent at the desk, which are more than the hours actually worked.

    Are 25 or 50-minute blocks better?

    There's no right answer for everyone. 25-minute blocks have more frequent, shorter breaks; 50-minute ones have fewer but longer ones. Change the length on the dial and you'll see how the finish time moves.

    How many hours a day should I study if I work?

    It depends on the exam and on how many weeks are left, not on a fixed number. On the dial you can set 2 or 3 hours and an evening start to see when you'd finish. For the math over the weeks, there's the page on how many hours to study for an exam.

    Can I do the blocks with someone?

    Yes. Every block is a time on the grid: you book it and do it on a video call with another person who booked the same time, or you send a link to someone you know, up to 5 dates in one invite. It's free, 18+ only.
