How is the days-until count calculated?

The tool compares each exam date against today's date at midnight, counting whole calendar days. An exam today shows 0, tomorrow shows 1, and past exams are marked as completed.

What do the colours mean?

Red means the exam is within three days, amber means within a week, and green means more than a week away. Completed exams are shown in muted grey so they drop out of your focus.

How are collisions detected?

Any two exams on the same calendar day are flagged as a same-day clash, and any pair on consecutive days is flagged as back-to-back. Both patterns warn you that revision time is tight.

Is my exam data stored anywhere?

No. Everything runs in your browser and nothing is sent to a server. Reloading the page clears the list, so keep your own record if you need it later.

Can I plan exams across different months?

Yes. The list sorts every exam by date regardless of month, so a planner spanning the end of one month into the next still shows the correct ordering and countdowns.

What is the Academic Calendar Exam Planner?

Enter exam names and dates to generate a visual calendar grid with days-until countdowns, colour-coded by urgency, so you can spot study-plan collisions and back-to-back papers during finals period at a glance. It runs free in your browser on Gera Tools, with nothing uploaded.

Finals season turns into a logistics problem fast: five or six papers, some clustered on the same day, others stranded a week apart. This planner lays them all out in date order with a live countdown to each, so the shape of your exam period is obvious before you build a revision timetable around it.

How it works

Each exam date is compared against today at local midnight. The number of whole calendar days between the two gives the countdown:

daysUntil = floor((examMidnight - todayMidnight) / 86400000)

A result of 0 is “today”, a negative number is “completed”, and positive values are days remaining. Urgency colours come from simple thresholds:

daysUntil < 0   -> done   (muted)
daysUntil <= 3  -> red
daysUntil <= 7  -> amber
otherwise       -> green

Spotting collisions

After sorting by date, the planner walks the list pairwise. Two exams sharing a date are a same-day clash; two exams one day apart are back-to-back. Both are the classic ways a study plan falls over, so they are surfaced as explicit warnings.

Building a revision timetable from the calendar

Once you can see the full shape of your exam period, a few planning principles become easier to apply:

Work backwards from each exam. If an exam is in 21 days, you have roughly 3 weeks to revise that subject. Block the final 3 days before the exam for consolidation and past papers, not new material. The 18 days before that are for coverage.

Give the hardest subject the most time, not the nearest exam. A common mistake is spending the most time on whichever exam comes first. Add your exams to this planner sorted by difficulty, not date, to see which subjects need the most days even if they are not next.

Handle same-day clashes by finishing early. If two papers fall on the same day, you cannot split the day for exam-morning revision. Finish your preparation for both subjects the day before and treat the gap between exams as rest, not cramming time.

Use the colour coding proactively. The moment a paper turns red (under 3 days), switch exclusively to past-paper retrieval practice for that subject. New content rarely sticks in 72 hours; practising recall does.

Tips for multi-subject finals periods

Add every paper including optional ones, so you see the full load.
Include resit dates if applicable — they often fall mid-term and collide with coursework deadlines.
Export or screenshot the list once you have it right; the browser does not save data between sessions.
If you see four consecutive days of exams, flag the day before the first one as a consolidation day, not a continuation of deep revision.
