This article presents a study of the social organisation of the national memories of Lithuania, Latvia, and Estonia (the Baltic states). It draws inspiration from and expands the scope of the application of Eviatar Zerubavel’s largely unexplored methodological tools for the study of calendars. Accordingly, the purpose of this paper is threefold. First, this paper offers an application of the above tools to the case of the Baltic states. Second, by doing so it provides an overview of comparative patterns within Baltic calendars. Third, it is argued that by exposing the social organisation of national memory, this approach offers insight into silences, providing an entry point for an engagement with amnesiology, as coined by Liedeke Plate.
