People who wait to file their federal income taxes until the last minute have a few extra days this year because of a holiday in Washington D.C, according to IRS spokeswoman Karen Connelly.

She says the Emancipation Day holiday celebrates the signing of the Emancipation Proclamation by President Abraham Lincoln in 1862.

Because the holiday falls on Friday, April 15, which is usually the deadline, the last day to file federal tax returns has been moved back to the next available weekday, which is Monday, April 18.
