Daily Time Quiz
Five questions, one shared puzzle a day — how fast is your clock math?

Why practice time math?
Elapsed-time math shows up everywhere adults actually do arithmetic: reading a timesheet, checking a night-shift schedule, working out whether a 7:45 AM start and a 4:05 PM finish really adds up to eight paid hours. It is also one of the skills students consistently find hardest, because clocks are base-60 while everything else they practice is base-10 — the “borrow” step works differently.
Each daily question maps to a real ClockMath tool, and every explanation shows the mental method: count up to the next full hour, add whole hours, then the leftover minutes. Miss one and the quiz points you at the matching calculator — duration, decimal hours, or work hours — so you can check the same math with real numbers.
Teachers: practice mode is unlimited, untimed, and needs no accounts — it works fine on a classroom of shared devices, and everyone gets the same daily puzzle to compare against.
Frequently asked questions
Is the daily quiz the same for everyone?
Yes — each day has one shared five-question puzzle, generated from the date itself, so every player worldwide answers the same questions. That is what makes the daily leaderboard a fair comparison.
When does a new quiz come out?
At midnight UTC, every day. The leaderboard resets with it, so each day is a fresh start no matter how yesterday went.
How is the score calculated?
One point per correct answer, out of five. The leaderboard ranks by score first and breaks ties by solving time — and the clock only runs while a question is on screen waiting for your answer, so reading the explanations costs nothing.
What kind of questions are asked?
The five daily questions always cover the same real-world skills: elapsed time between two clock times, durations that cross midnight, adding hours and minutes to a time, converting hours and minutes to decimal hours, and working out paid hours on a shift with an unpaid break.
Do I need an account to play or join the leaderboard?
No signup, ever. Your results and streak are saved on your device, and the leaderboard just takes three letters, arcade style. Practice mode is unlimited and free too.
