Revision Calendar Tool Calculator

Turn syllabus into a realistic weekly revision roadmap. Adjust difficulty, breaks, and buffers without stress. Stay consistent, track progress, and finish with confidence always.

Build Your Plan

Enter your date range, weekly availability, and topics. The tool creates a spaced revision calendar and reserves final buffer days for review and testing.

Higher values give harder topics more time.
Example: 0.25 means each revision is 25% of learning time.
Only checked days are included in the calendar.
Use dates like YYYY-MM-DD, separated by commas or spaces.
Duplicates are removed automatically.
Example: Trigonometry | 5 | 4. If you omit difficulty or hours, defaults are used.

Example Data Table

This sample shows the expected topic format and how difficulty and hours shape the schedule.

Topic Difficulty (1–5) Learning hours Notes
Algebra 4 3 More practice sets, longer recall sessions.
Geometry 3 2 Standard coverage, then spaced review.
Trigonometry 5 4 Extra time for identities and mixed problems.
Statistics 2 2 Quicker pass, focus on formula recall.
Calculus 5 5 High weight, strong revision cadence.

Formula Used

1) Total available study hours
We count only selected weekdays between your start and exam dates, skipping holidays. Then:
Total Hours = (Available Study Days × Hours Per Day)
2) Weighted learning hours per topic
Harder topics get extra time based on the difficulty weighting slider:
Weighted Hours = Base Hours × (1 + W × (Difficulty − 3) / 2)
Here, W is the difficulty weighting (0 to 1).
3) Spaced revisions
After each topic’s first learning block, revisions are scheduled at your chosen day intervals:
Revision Hours = Weighted Hours × Revision Ratio
If a target date is busy, the task carries forward to the next available study day.

How to Use This Calculator

  3. Enter hours per study day, then set buffer days before the exam.
  4. Add topics using Topic | Difficulty | Hours format.
  5. Adjust difficulty weighting and revision ratio.
  6. Press Submit to generate the calendar above the form.
  7. Use Download CSV or Download PDF to save it.

Capacity Planning

A revision calendar works best when time is treated as a budget, not a wish. This tool converts your study window into available study days by filtering selected weekdays and skipping listed holidays. It then multiplies those days by your planned hours per study day, creating a realistic capacity figure you can manage.

Difficulty Weighting

Difficulty inputs help distribute effort where it matters. Each topic’s base learning hours are adjusted using a weighting factor, so higher difficulty topics receive additional time while easier topics stay lean. This approach reduces the common mistake of giving every chapter equal attention, which often leaves high‑risk areas underprepared.

Spacing Intervals

Spacing is built into the schedule through revision intervals. After a topic’s initial learning session, the tool schedules follow‑up reviews at your chosen day gaps, such as 1, 3, 7, and 14 days. Each review uses a revision ratio to estimate how much time is needed to refresh memory and practice retrieval, improving retention compared with rereading notes.

Buffers and Carryover

Output quality improves when the last days are protected. The buffer setting reserves final study days for full review and a timed mock test. These sessions consolidate weak areas, verify pacing, and generate an error log you can fix quickly. If a revision day is already full, the tool carries work forward to the next available study day.

Results and Exports

To interpret results, focus on planned hours, spare hours, and warnings. Planned hours show how much of your capacity is scheduled. Spare hours indicate flexibility for setbacks, extra practice, or rest. Warnings appear when learning or revision cannot fit, guiding you to increase hours, reduce scope, or extend the date range.

Exports support accountability and collaboration. The CSV download helps you sort by date, bundle sessions by week, and import tasks into planning tools. The PDF download creates a printable snapshot for sharing with a tutor or revising offline. After each session, record mistakes and adjust the topic hours, then regenerate the calendar to reflect new reality. This feedback loop improves estimates, protects buffer days, and increases completion rates. In a few cycles, the schedule becomes a consistent habit, not a stressful guess. Use spare hours for drills, rest, and confidence checks.

FAQs

How are available study days calculated?

The tool includes only the weekdays you select between the start and exam dates. Any holiday dates you enter are removed, so the calendar reflects your true study availability.

What does difficulty weighting change?

It increases or decreases learning time based on topic difficulty. Higher weighting shifts more hours toward tougher topics, helping you reduce risk in areas most likely to affect your score.

Why use spaced revision intervals?

Spacing supports long-term retention by revisiting material after short and longer gaps. It improves recall and reduces cramming, especially when combined with practice questions and error review.

What if my schedule is too tight?

You will see warnings when tasks cannot fit. Increase hours per study day, reduce topic hours, remove low-priority topics, or extend the exam date range to add more study days.

How should I use buffer days?

Reserve them for full review, mixed practice, and a timed mock test. Use the results to create a short list of weak points, then fix those with focused drills.

How do the CSV and PDF exports help?

CSV is best for sorting, weekly grouping, and importing into planners. PDF is best for printing or sharing. Both make it easier to follow the plan consistently.
