April 15 hosts National That Sucks Day, an American holiday established by a web content producer who astutely noted the significance of this date due to various unfortunate events. Among the most noteworthy tragedies linked with April 15 are the sinking of the "Titanic," a colossal and purportedly indestructible early 20th-century ship that ultimately met its demise in the Atlantic after colliding with an iceberg. Additionally, this infamous date marks the passing of President Abraham Lincoln.
