A topic list can look manageable until its total minutes are compared with the actual study days left. A useful calendar needs to show work that fits and work that does not.
Revision Calendar schedules topics in the order entered, skips one optional weekly rest day and repeats the list for the number of passes you choose.
Estimate a topic in focused minutes
Give each topic a name and a time estimate for one pass. Two passes repeat the same estimate twice. The tool does not assume that the second pass will be faster or that a topic has been mastered after it.
Set the first and last study dates, daily focused minutes and a weekly rest day. Both boundary dates are considered, subject to the selected rest day. A window cannot exceed 120 calendar days.
Topic order is deliberate. The scheduler finishes a topic before continuing to the next, and finishes one complete pass before starting the next pass.
Twelve study days inside a two week window
For a window from 10 to 23 August 2026, select Sunday as the rest day and allow 120 focused minutes per study day. The two Sundays are skipped, leaving 12 study days and 1,440 minutes of capacity.
Enter Mechanics at 120 minutes, Algebra at 180, and Chemistry at 240. One pass totals 540 minutes. Two passes need 1,080 minutes, leaving 360 unused minutes in the window.
A topic can continue across dates. Algebra’s 180 minutes take one full 120 minute day and another 60 minutes on the next available day. The remaining capacity that day goes to Chemistry.
Carryover is unfinished work, not a hidden extension
If the final date arrives before all topic minutes are assigned, the result shows carryover. The calendar does not extend beyond your entered window or move work onto the rest day.
Try reducing scope, changing daily capacity or starting earlier. Which adjustment is realistic depends on your timetable, rather than on the calculator.
Use the rows as a plan, not a completion record
The worksheet contains dated sessions and pass numbers. It does not track completed work, retain progress or send reminders. Mark your actual progress elsewhere and update the remaining estimates as needed.
Keep time for testing yourself and revisiting weak material inside the topic estimates if you want those tasks scheduled. Simply calling a topic revised does not measure recall.
For a deadline tied to an examination, compare the available days with Exam Study Countdown. Its exam day boundary differs from this inclusive study window.
