Add Holidays To Your Google Calendar

I just learned you can add holidays to your Google Calendar by clicking the Add button in the “Other calendars” section.  After you click the Add button select “Add a public calendar”.   

Click the “Add Calendar” button to any public calendar you wish to add to your calendar.  For instance as you can see in the screenshot below I added the Phases of the Moon, Google Doodles, and US Holidays public calendars.  If you didn’t already know this trick (like me), I hope you find this useful.
