Limits:100rows (rosters64/50 as shown),256KiB backup,30,000text units,100,000search visits,20second worker deadline,40PDF pages/8MiB. PDF uses local Liberation Sans with actual glyph checks; no RTL/complex shaping. Unsupported print text remains in the backup. Removing a row removes its linked assignments; editing/reordering preserves positional identities. Roster/draw changes clear tournament results. Roster/reference names must be unique for generation; incomplete drafts may repeat them.

How to use

  1. Add

    Add routines with explicit target dates, and mark only the dates you have actually recorded.

  2. Create plan

    Try this concrete example: targets[Nov2,Nov3,Nov4],marked[Nov2] → target3,completed1,unrecorded2

  3. Export backup

    Review marks that fall outside the target dates separately. A target date with no record is not automatically a failed habit.

Questions

Are target dates generated from a recurrence?

No. You supply the actual target dates, and the summary counts where they overlap with your manual marks.

What should I correct before generating?

Use real, unique ISO dates. Duplicate dates within either list are rejected.

What does this output not establish?

No reminders, inferred streaks, health assessment or account history across devices.
