Your lessons in Google Calendar, Apple Calendar or Outlook

There are three ways, from most to least automatic:

1. Subscribe to your NowLesson calendar (Settings → Your lessons in your calendar): all your lessons appear and update automatically.
2. Teachers: connect Google Calendar (Settings): your lessons are created in your calendar, and anything you’re busy with there isn’t offered as a slot.
3. From each email: “Add to Google Calendar” and “Add to Apple Calendar” buttons (the latter also works for Outlook).
