Google Calendar - Interesting Calendars

I have just found a great feature of gCal called 'Interesting Calendars'.

1) Go to:
2) In the bottom left, click the arrow on 'Other Calendars' > 'Browse Interesting Calendars' or go to 'Settings', then 'Calendars' then 'Browse Interesting Calendars'
3) Choose a category e.g. 'Soccer' > 'England' > 'English Premier League' and choose your team.

Pretty useful!
