First off, only posers call it "St. Patty's Day". It's SAINT PATRICK'S DAY. Don't look like a poser.

You do need to look Irish though. You're supposed to wear green today, but if you want to go for the authentic Irish look, dye your hair red today.

Who is this "St. Patrick" guy anyway? And why does he get a day? Know the answers to these questions if anyone asks! St. Patrick is the patron saint of Ireland. St. Patrick's Day is March 17 every year because he died on March 17. His deathiversary was made an official Christian feast day in the early 17th century and it is observed by the Catholic Church, the Anglican Communion -- especially the Church of Ireland, the Eastern Orthodox Church, and Lutheran Church. It is a religious day, and also an official national holiday in Ireland, Northern Ireland, two Canadian provinces, and Montserrat.

What is "The Feast Of St. Patrick"? It's another name for St. Patrick's Day, and it's important to know that if you're a religious person who has given something up for lent, you get a day off from that. So feast on!

Make sure you eat Irish food today. You like corned beef? Have at it today. Cabbage? Potatoes? Go nuts. This website has 15 traditional Irish foods to eat today. If you're going to roleplay the whole Irish thing today, do it right.

Make sure if you eat or drink something green today it's food coloring causing it to be green. Safety tip.

I'm not Irish but you can kiss me anyway. Hey, it's worth a shot.

Best place to be Irish in the Cedar Valley today? Jameson's in downtown Waterloo is as Irish as it gets, and it will be packed tonight. It will probably be packed at lunchtime.

Keep the jokes about leprechauns and potatoes and C-4 to yourself today. Be respectful. They're still touchy about the potato famine, and probably about the whole bombing thing. And leprechauns aren't real.

Make sure your friends keep their phones in the car. Do you really want your public drunkenness today all over Facebook and Instagram?

DESIGNATED DRIVER! Have a sober friend (this person is a real friend by the way, and you should never mistreat your real friends) be the keeper of all your keys and phones. This person is a lifesaver. If you don't have any sober friends (or friends period) they have these things called taxi cabs. You pay someone and they will give you a ride home, or to a booty call, or wherever.

Get married today! St. Patrick's Day is considered the luckiest day of the year to get married... unless it falls on a Saturday. According to this Irish proverb, Saturday is the worst day of the week to get married: "Marry on Monday for wealth/ Tuesday for health/ Wednesday the best day of all/ Thursday for losses / Friday for crosses/ Saturday for no luck at all."

Have a great deathiversary today!
