4. Click Add calendar. The calendar appears on the left, under "Other calendars."

Tip: It might take up to 24 hours for changes to show in your Google Calendar.

Once subscribe, you can show or hide calendars you’ve already subscribed to:

2. At the top left, tap Menu  .
3. Check or uncheck your preferred calendar.
