Today is, of course, the traditional Tax Day for U.S. earners. The deadline moves to the next business day when it falls, like today, on a Sunday. When that next business day is an official federal holiday, as happened this year, the date gets pushed ahead yet again.
But April 15 throughout the ages also has had its share of other momentous events.
Jackie Robinson's MLB debut
On April 15, 1947, Jackie Robinson donned #42 for the Brooklyn Dodgers and when he took the field, he broke Major League Baseball's color line.
Revolutionary War, beginning of the end
The Continental Congress ratified preliminary articles of peace ending the Revolutionary War with Great Britain on April 15, 1783.
RMS Titanic sinks
The luxury passenger cruise liner collided with an iceberg in the north Atlantic at 11:40 p.m. (ship's time) on Sunday, April 14, 1912. The Titanic, once touted as unsinkable, went under the waves 2 hours, 40 minutes later in the early morning of Monday, April 15, 1912.
