Tax deadline pushed back

[Drolefille]

That's cool, I knew they pushed it back if it was on a weekend, but how has this not come up more often if the 16th is always Emancipation day?
From wiki

The municipality of Washington, D.C. celebrates April 16 as Emancipation Day. On that day in 1862, President Abraham Lincoln signed the Compensated Emancipation Act for the release of certain persons held to service or labor in the District of Columbia. The Act freed about 3,100 enslaved persons in the District of Columbia nine months before President Lincoln issued his famous Emancipation Proclamation telegraphing the eventual end of slavery to the rest of the nation. The District of Columbia Compensated Emancipation Act represents the only example of compensation by the federal government to free enslaved persons.

On January 4, 2005, Mayor Anthony Williams signed legislation making Emancipation Day an official public holiday in the District. Each year, a series of activities will be held during the public holiday including the traditional Emancipation Day parade celebrating the freedom of enslaved persons in the District of Columbia. The Emancipation Day celebration was held yearly from 1866 to 1901, and was resumed under the leadership of Councilmember Vincent Orange as a tradition and historic celebration in 2002.

So, it's the second year of it being an official holiday.

Hmmm, what is Patriots Day on April 16th in Massachusetts?

Patriots' Day (sometimes spelled Patriot's Day or Patriots Day) is a civic holiday in the U.S. states of Massachusetts and Maine (once part of Massachusetts), and a public school observance day in Wisconsin. Traditionally it was observed on April 19, in honor of Lexington and Concord, the first battles of the American Revolutionary War, fought on that date in 1775. Since 1969, however, the holiday has been observed on the third Monday in April, providing a three-day long weekend.

The Boston Marathon is run on this day every year. Also, the Boston Red Sox have traditionally played a home game at Fenway on this date every year since 1960, typically starting at 11:00 AM ET. Many schools, elementary through high school, take the entire week off as an "April vacation."

Occasionally Tax Day falls on this day, causing the tax deadline to be extended by a day for the residents of Connecticut, Maine, Maryland, Massachusetts, New Hampshire, New York, Vermont, and the District of Columbia. This is because the IRS processing center for these areas is located in Andover, Massachusetts, and is closed on Patriots' Day.
