Opening your local workspace…

How it works.

  1. 01Choose or drop an ICS file.
  2. 02Inspect event count, date range and diagnostics.
  3. 03Browse events or test recurring occurrences in a finite window.

The important details.

Event values retain their DATE, UTC, floating or TZID identity. A floating time is never silently interpreted in your browser timezone.

A good question.

Does viewing subscribe to the calendar?

No. The file is read in this tab. Nothing connects to your calendar account.

Keep going.
