In addition to remembering that Euskal Herria is a nation, the Euskal Herria Batera group has stressed the need to celebrate the national day together, and has launched a call for this: the celebration will take place on 11 April in the Kursaal Auditorium of San Sebastian. It will be dressed in a series of one-week events, although more details will be given on these celebrations later.

Euskal Herria Batera announced on the eve of the 2024 Aberri Eguna that it will be a joint celebration in 2025. They have now confirmed this, according to the year.

The main objective is to jointly celebrate the Aberri Eguna: "We will celebrate a single unitary moment, with the objective of creating a meeting space under the same feeling, under the feeling of belonging to a people, even those who are not born in the Basque Country, feel part of it." The event, which will be held before April 11, will invite different political and social actors to participate in it. They will then be called to the Aberri Eguna.

Friday, April 11, 2025, will be the day of the Aberri Eguna joint. Later, during the Aberri Eguna, each Abertzale formation will perform a political act at the Euskalduna Palace in Bilbao.
