In short: Exam Countdown Calculator
There are 90 days left before the exam, which reads as 2 months, 29 days and comes to 12.86 weeks, of which 64 are weekdays. At the hours a day entered that gives you 360 study hours in all, or about 72.00 hours for each of the subjects.
What is Exam Countdown?
An exam countdown is the days between today and the exam, turned into study time at the hours a day you can actually keep up.
How is Exam Countdown calculated?
Multiply the days left by the hours a day you can study, then divide by the number of subjects to see what each one gets. The weekday count is given separately, because most people study differently at the weekend.

Questions people ask
How many hours a day should I enter?
The number you can sustain for the whole period, not the number you manage on your best day. Most people plan on a figure they cannot hold and then feel behind. Entering a realistic figure gives you a plan that survives contact with the term.
Should every subject get the same time?
No, and the even split here is only a starting point. Weight the subjects you find hardest, and those that carry more marks, more heavily. Use the figure as a budget to divide rather than a rule.
Does it count holidays?
It counts every calendar day, and shows the weekday count separately so you can see the split. Public holidays and festivals are not removed, because they differ by state and by school. Subtract the ones that will genuinely cost you study time.
What if the exam date has passed?
The tool says so rather than showing a negative count. Change the date, or set the start date earlier if you are looking back at a period that has already gone.
