More than a countdown
Any clock can tell you the exam is in 23 days. The number that changes what you do today is different: how many of those days will you study, and how many hours does that add up to? That is what this countdown shows under the timer, and it is usually smaller than people expect. Twenty-three days with weekends off and three hours a day is 51 hours, which is about ten past papers and a revision pass, or roughly one subject's syllabus from scratch. Seeing the number early is what turns "I have ages" into a plan.
How the numbers are worked out
- Days, hours, minutes, seconds count down live to the exam date and start time (9:00 am if you leave the time empty).
- Study days left are every day from today up to the day before the exam. The exam day is never a study day. Tick "skip weekends" if Saturdays and Sundays are not real study days for you, and the count drops accordingly.
- Study hours available is study days times the hours per day you set on the slider. Be honest with the slider: three focused hours are worth more than six hours of being near a book.
- Pomodoros is that time in 25-minute focus blocks with their 5-minute breaks, which is a useful way to picture it. "140 pomodoros" sounds like a lot of chances to get something done; "70 hours" sounds like an abstraction.
- Weeks and hours a week show the same thing at the scale you actually plan in.

What to do at each stage
The verdict under the timer changes with how far away the exam is, because the right activity changes too.
90 days or more: relaxed start
You do not need to grind. You need a light habit (an hour a day, a chapter a week) so the exam never becomes an emergency. The most useful thing you can do this far out is to stay level with your classes: finishing each chapter before the next one starts is what prevents the backlog that causes cramming later.
30 to 89 days: plan mode
This is when a timetable pays off most, because there is still slack to fit everything in. Make the study timetable, study each chapter twice with at least a week between passes, and set a weekly check of chapters finished against the plan. When you slip, adjust the plan rather than abandoning it.
7 to 29 days: focus mode
Enough time to finish a syllabus and revise it, if the hours actually happen. Decide now, using past papers, which chapters get done properly and which get skimmed. Fix a daily start time. Reserve the last five days for revision only and treat that as the deadline for new material.
Under a week: final stretch
No new chapters. This is for recall, timed past papers and fixing the mistakes they expose. Revise from memory first and check the book second, because re-reading feels productive and mostly is not. Keep sleeping normally: the night's sleep is where the day's revision gets consolidated, and there is no way to cram that.
Exam day
Summaries once, a real breakfast, everything packed, phone away an hour before. Nervous scrolling has never improved a grade.
Turning the hours into a plan
Knowing you have 51 hours is only half the question; the other half is how many you need. The study time calculator estimates that from your chapters left and how well you know them, and the button under the result carries your exam date and daily hours across so you can compare the two numbers directly. If "need" is bigger than "have", the syllabus completion calculator helps you decide what to cut.
Frequently asked questions
How many days before an exam should I start studying?
For a single school or college exam, two to three weeks of regular study is comfortable; for board exams, finals or competitive exams, two to three months. The real answer is how many hours you need divided by the hours a day you can manage, which is what the study time calculator works out. Starting earlier at a lighter pace always beats starting late at a heavy one.
How many study hours do I have left before my exam?
Count the days from today to the day before the exam, drop any days you will not study, and multiply by the hours a day you can really focus. This countdown does that for you and updates live. Most students find the number is smaller than they assumed, which is useful to know early.
Does the countdown count the exam day?
The timer counts down to the exam start time, so the exam day is included in the days, hours and minutes. The study days and study hours exclude it, because you will not be studying new material on the day itself.
Can I save or share my exam countdown?
Yes. Your exam name, date and settings are stored in the page link, so you can bookmark it, add it to your phone home screen or send it to friends sitting the same paper. Nothing is stored on a server.
