The phrase "When We Were Young 20" likely refers to one of two main things:
- The song "When We Were Young" by Adele, which is from her album "25" released on November 20, 2015.
- The annual music festival called "When We Were Young," which focuses on rock, emo, pop-punk, and related genres. The festival began in 2017 and, since 2022, is held at the Las Vegas Festival Grounds. The 2025 edition of the festival will take place on October 18 and 19, 2025, featuring bands like Blink-182, Panic! At The Disco (celebrating the 20th anniversary of their album "A Fever You Can't Sweat Out"), Weezer, Avril Lavigne, and more.
If you are referring to the festival happening in 2025 (the "20" possibly indicating the year or a 20th anniversary), the exact dates are October 18-19, 2025.
