Subtract ordered tasks and a final buffer from a deadline to calculate start and timeline.

Subtract ordered tasks and a final buffer from a deadline to calculate start and timeline.

Planning aid using entered durations only; no traffic, weather, transport or crowd forecasts. Set official carrier or venue deadlines yourself. Start=target−task total−final buffer; preserve task order and show buffer separately. Browser local timezone, elapsed minutes, calendar-day offsets and UTC offsets; no timezone conversion. Nonexistent DST targets rejected; repeated time uses browser’s earlier occurrence. Include task-specific margins in durations.
