System: "Il n'est possible de s'inscrire aux grandes manœuvres commémoratives qu'à certains moments précis pendant la durée de l'événement saisonnier."
System: "Vous pouvez aussi le faire en parlant au guide des manœuvres, qui est uniquement disponible lorsque les manœuvres sont en cours."

Which translates to:

NPC: "Multiple exercises are organised randombly during the Rising event. To participate, one must talk with a Rising Recuiter."
System: "It is only possible to participate in the great commemorative exercises at certain times during the event."
System: "You can also do it by speaking with the "exercises guide" [(Rising Recruiter?)], which is only available when exercises are currently ongoing."

So, the NPC says it's random, the system text says it's "at certain times", which might mean fixed times. Who knows.
Given the fact they haven't said anything about it in any other language, i'm going to assume it was mistranslated.
