Deadline & Milestone Planner guide

Create and export

Choose a deadline, working or calendar days, weekends and excluded dates.

List stages in execution order with the effort days for each.

Build the backward plan, review any adjusted deadline, and export the milestones.

Supported formats and limits

Up to 30 stages, 1–90 days each. Working-day mode skips selected weekends and manually supplied exclusions. If the requested deadline is excluded, the final stage ends on the preceding working day and the adjusted date is shown. Stage intervals include intervening non-working days; CSV reports chosen effort separately. This is date planning, not a legal deadline calculator. No automatic statutory holidays.

Local processing

All files, events, names and notes stay in browser memory. No calendar-account connection, upload, external model, background reminders or automatic storage. Refreshing clears the workspace; save an export to keep your work. Exported calendar files require an explicit import into a calendar app; they do not create reservations or synchronize changes.
