Today’s the day when virtually everyone claims to be at least a wee bit Irish.

But can you tell the blarney from the facts on how the day is celebrated?

Here are a few tidbits to share with friends over corned beef and cabbage and a green beer – or better yet, a Guinness:

Cabbage shipments increase by 70 percent in the United States during the week of St. Patrick’s Day.

13 million pints of Guinness will be consumed worldwide on today.

51.2 percent of Americans plan to celebrate St. Patrick’s Day.

82.1 percent of those celebrators plan to wear green.

The market value of a leprechaun’s pot of gold, which contains 1,000 1-ounce gold coins, is $1.2 million.

The world’s shortest St. Patrick’s Day parade is 98 feet, and it’s in Hot Springs, Arkansas.

The first St. Patrick’s Day parade was in 1737 in Boston, according to WalletHub. Maybe. The U.S. Census Bureau says the first parade was in 1762 in New York City. (The first St. Patrick’s Day parade in Denver was in 1889.)

Irish ancestry is the second most cited European ancestry in the United States, after German. According to the Census Bureau, 33.1 million Americans claim Irish ancestry.
