The band's name was derived from '41 days of summer' member-first-camp summer break date in 1996.

Their 2001 debut All Killer No Filler - featuring the international singles Fat Lip and In Too Deep - established their commercial breakthrough. They have continued releasing material across multiple decades, evolving from pop punk toward more harder rock and metalcore-adjacent material across the 2010s and 2020s.

Whibley was married to Canadian pop singer Avril Lavigne from 2006-2010. The band dissolved in January 2025 after a final farewell tour following the release of Heaven:x: Hell (2024). Their foundational influence on contemporary Canadian pop punk is widely cited.
