What are the limits of Calendar Time Shifter?
Local-days mode preserves wall-clock times in the selected display zone; absolute-minutes mode preserves elapsed offsets. All-day events require whole-day shifts. Exports explicit occurrences, not recurring source rules. Data stays in browser memory. No account connection, automatic storage, live holiday feed or background reminders. ICS exports must be imported into your own calendar app.
