ZEROBASEONE is giving fans (ZEROSE) two ways to celebrate member Sung Han Bin's birthday this year. According to the group's official Twitter account @ZB1_official, a special B-Day Live is scheduled for Friday, June 12, 2026 at 6:00 PM KST, streaming live on the ZB1 Official YouTube channel. A separate post from the same account also announced a fan-vote event running in the hours leading up to the broadcast.

The birthday stream was announced directly by the group's official account with the message "Happy Birthday to HAN BIN 👼", confirming the date, time, and platform. ZEROSE around the world can catch the celebration live on YouTube — just remember to convert 6:00 PM KST to your local time zone. That's 9:00 AM UTC, 5:00 AM ET, and 2:00 AM PT on June 12.

Ahead of the live stream, fans also have a chance to make their voices heard. A second post from @ZB1_official announced ZEROSE's Choice 2026, a fan-vote event tied to Han Bin's birthday. The voting window opens on June 11, 2026 at 6:30 PM KST and closes on June 12, 2026 at 10:00 AM KST — giving ZEROSE roughly 15 and a half hours to participate before the live stream begins later that evening.
