On what date did Ateez debut?

Ateez debuted on October 24, 2018.

The group marked its official debut by releasing its first extended play, Treasure EP.1: All to Zero, through KQ Entertainment. Two lead singles, “Pirate King” and “Treasure,” were released with music videos, and Ateez held its debut showcase on the same day.

The date is sometimes confused with later releases in the group’s discography. January 15, 2019, is associated with the release of Treasure EP.2: Zero to One, while May 31, 2024, is associated with the original release date of Golden Hour: Part.1. July 20, 2018, was the premiere date of Code Name Is Ateez, the reality show that introduced the group before its official music debut.

Treasure EP.1: All to Zero began Ateez’s Treasure series, a sequence of releases that established the group’s early pirate-themed musical and visual identity. The debut EP reached number seven on South Korea’s weekly Gaon Albums Chart and sold 23,644 copies in 2018.
