Google Calendar (first session)
The .ics file imports into Google Calendar, Apple Calendar and Outlook — one event per study day listing that day's videos. Subscribing instead keeps the plan in step with the playlist: new videos become new sessions. In Google Calendar use Other calendars → From URL with the copied feed URL.
