Frequently Asked Questions

10 common questions about the reverse goal splitter tool.

Q1. Do I need to sign up?

No. The tool is free with no signup required. Your inputs stay in your browser's localStorage only.

Q2. How exactly is the reverse split computed?

We break the total span into 7-day weekly buckets. Each preset defines major tasks as percent ranges (e.g., "base building 0–25 %"). For each week we intersect those percent ranges with the week's percent range and keep the overlapping tasks. Daily tasks cycle through a 7-day preset-specific template (Mon–Sun).

Q3. Does it work for goals outside the 5 presets?

Yes. Pick the preset that matches your goal's shape (e.g., long & stepwise → book; short & intensive → exam) and overwrite just the goal title. The share URL and ICS export still work the same way.

Q4. What are the 25/50/75 % milestones?

They are the calendar dates at 25 %, 50 %, 75 %, and 100 % of the span. A 100-day plan highlights days 25, 50, 75, and 100, plus the major task that should be in progress at each point. Use them as mid-plan checkpoints.

Q5. Which calendars support the ICS file?

Standard iCalendar (.ics) — opens in Apple Calendar, Google Calendar, Outlook, and Naver Calendar. Each weekly block and the 4 milestones are added as all-day events.

Q6. What's different about the "Add to Google Calendar" button?

It opens Google Calendar's new-event page directly (no ICS import) to add just the final D-day in one click. For the full weekly plan, use the ICS download instead.

Q7. What if I set the start date to the past?

Works fine. Past weeks count toward the "Elapsed %" stat, and the "next 14 days" panel always starts from today. Useful for reviewing a plan that's already in progress.

Q8. What if the target date is on/before the start date?

The tool shows an error and doesn't generate a plan. You need at least a 1-day gap for a reverse split to make sense.

Q9. Does the plan shift if my timezone changes?

Dates are interpreted as local midnight in the browser, so the plan itself stays anchored. Switching timezones only re-anchors "today" — the calendar events don't slide.

Q10. Are other languages supported?

Currently EN and KO only. Additional languages (JA, ZH, etc.) will follow based on usage signals.
