No, today isn't the day that we drink green-tinted magnesium citrate and sing Celtic songs in the bathroom. "Evacuation Day" is a state holiday, of sorts, that celebrates the day the British left the Town of Boston.
According to Captain John Barker, they would have left on the 13th, but the wind was unfavorable. It remained so through the 16th, so I guess there was improvement when the British military woke up on the morning of the 17th. Or they were just plain turned off by all the green beer and people vomiting.
Here in Bristol County, we tend to call the day "St. Patrick's Day" and we use it to celebrate being Irish. Or pretending to be Irish.
If you're of the green-beer-drinking persuasion, I can understand why you'd want to limit your consumption to one day per year. If you actually enjoy Irish beer, I doubt you're going to want to save the Guinness for a single day in March. It's all very confusing to me, which is why I decided to spend the day with my wife instead of going to work. And have pledged to drink no green beer. Just an ounce or so of Jameson last night before bed. Followed by a heavy sleep. Quite abruptly.
It's Spring Break at the university, so there is no class. There, I said it.
Evacuation Day means that some schools are closed and state offices have an official holiday. During university vacation time, they make it a "floating" holiday. That means you can take it now when you are really busy or tell your boss that you'd like to take it at some other time when you're really busy in the next 2 months or so. It does not mean "a holiday during which you drink enough beer to float your liver." But there is some confusion on this point.
A happy day to you all, and don't let the amateur revelers get you down.
