Similarly, duodecennial for 12 year and sesquicentennial for 150 year celebrations.

And sesquipedalian, literally 'foot-and-a-half-long' for many syllabled words or speech.

Finally, Susquehanna is a river flowing from central New York to Chesapeake Bay.

Susquehanna was also the name of a hat manufacturing company in an old Abbot and Costello routine.

I always remember the important stuff.

With the -ennial ending most of the words are the same: vicennial = 20 years, etc.

The U.S. Government takes a decennial census.

You can look up Supreme Court decisions (the old-fashioned way) in West's Decennial Digests.
