September 9 Officially Becomes Attack on Titan Day With Special Livestream
September 9 has officially been designated as Attack on Titan Day, with a special livestream planned for fans. The new annual celebration gives the franchise another major date on the anime calendar.

Attack on Titan gets an official day
Fans of Attack on Titan now have a new date to mark on their calendars. September 9 has officially been designated as Attack on Titan Day, creating a dedicated annual occasion for celebrating the hit anime franchise.
The announcement also includes a special livestream connected to the occasion. While the designation itself is a celebration rather than a new television season announcement, it gives the franchise a fresh event around which future promotions and fan activities can be organized.
When is Attack on Titan Day?
Attack on Titan Day takes place on September 9. The date will be associated with official franchise activities and the announced livestream.
For longtime viewers, the event provides another opportunity to revisit the series and its characters. Attack on Titan has already completed its main anime story, so anniversary-style events are an important way for the franchise to remain active with its audience.
Why the announcement matters
Attack on Titan remains one of the most internationally recognized modern anime franchises. An official commemorative day gives the property a recurring promotional moment and provides a natural occasion for merchandise campaigns, special broadcasts, fan celebrations and future announcements.
The September 9 event may also attract viewers who discovered the series after its conclusion and want to participate in the wider fan community.
What fans can expect
The currently announced centerpiece is a special livestream. Fans should watch official channels for the confirmed schedule and any additional programming connected to Attack on Titan Day.
It is important to distinguish confirmed information from fan speculation. The announcement establishes the commemorative day and livestream, but it should not automatically be interpreted as confirmation of a new sequel series.
Attack on Titan's continuing legacy
The franchise's influence extends beyond its original television run, with international streaming, merchandise, music, events and fan communities continuing to keep the series visible.
September 9 therefore represents more than a simple calendar entry. It is a new recurring opportunity for the franchise to celebrate its history and reconnect with its global audience.
