On what date did the series finale of How I Met Your Mother air?

The series finale of How I Met Your Mother aired on March 31, 2014.

Titled “Last Forever,” the finale was presented as a two-part, one-hour event combining the show’s 207th and 208th episodes. It aired back-to-back on CBS and brought the nine-season story of Ted Mosby recounting how he met the mother of his children to its conclusion.

The finale drew 13.13 million U.S. viewers, making it the most-watched episode of the series. Its ending became one of television’s most debated sitcom finales, particularly because of its treatment of Tracy McConnell, the Mother, and Ted’s relationship with Robin Scherbatsky. An alternate ending was later included with the home-media release.

A common mix-up is September 23, 2013, which was the premiere date of the ninth and final season—not the series finale. The finale’s original broadcast date was March 31, 2014.
