Example Schedule Snapshot

Sample rows to show how the plan is structured.

Date	Planned minutes	Focus	Notes
2026-03-02	55	Research	Collect sources and build an outline.
2026-03-05	55	Draft	Write the first half with citations.
2026-03-10	0	Buffer	Catch-up and proofread calmly.

Formulas Used

Total calendar days = (Due date − Start date) + 1.
Filtered workdays = calendar days − weekends (optional) − break dates.
Buffer days = ceil(filtered workdays × buffer percent ÷ 100).
Planned workdays = filtered workdays − buffer days.
Total minutes = total hours × 60.
Daily target minutes = ceil(total minutes ÷ planned workdays).
Phase minutes = total minutes × (phase weight ÷ 100).
Writing estimate = target words ÷ words per hour.

FAQs

1) What does “buffer percent” do?

It reserves the last available workdays for catch-up. Use it for feedback, formatting, or unexpected delays. Higher values reduce planned days, so daily targets rise.

2) Should I exclude weekends?

If weekends are unreliable, exclude them for a more honest schedule. If you study on weekends consistently, include them to lower the daily minutes target.

3) What if my plan says “Tight”?

Increase sessions per day, raise session minutes, start earlier, or reduce total hours. You can also lower the word target or simplify research scope to shrink the workload.

4) How are phases assigned to dates?

The calculator splits total minutes by your phase weights. Dates are labeled by where each day’s cumulative minutes land inside those phase budgets, creating milestone dates automatically.

5) Can I use this for problem sets or coding tasks?

Yes. Treat “Draft” as solving and “Revise” as debugging or checking. Adjust phase weights so more time goes to practice, testing, and final review.

6) Are break dates removed from the timeline?

They are removed from the workday list, but they stay inside the calendar range. This keeps the due date unchanged while protecting time you marked as unavailable.

7) How should I pick total hours?

Start with your best estimate, then add a small cushion. If your assignment involves new concepts, choose a higher difficulty and consider adding more buffer days.
