"Losing a Whole Year" is a song by American rock band Third Eye Blind from their eponymous debut studio album (1997).

Third Eye Blind initially planned to release the song as their debut single, although they opted for "Semi-Charmed Life" at the suggestion of Elektra Records.

[2] Jenkins further discussed the meaning of the song, stating that it is about "a rich girl from Bernal Heights" and that it is "just lamenting the end of a relationship and all of its wasted time".

[6] Allmusic's Mike DeGagne agreed, writing that "its pop-friendly makeup of frolicking guitar and a welcoming tempo make it one of the band's most catchiest tunes.

"[7] "Losing a Whole Year" stayed on the Billboard Modern Rock Tracks chart for 14 weeks and peaked at number 13 on May 2, 1998.

In 2009, American post-hardcore band A Lot Like Birds, on their album Plan B, included a cover of "Losing A Whole Year" at the end of their song "Sesame Street is No Place for Vengeance" as a hidden track.
