Our familiarity with calendar age — to the point that it is hard to conceive of age without it — is the starting point of the inquiry this workshop seeks to contribute to, aiming at the historicization of this fundamental social category. The workshop invites contributions from fields as diverse as the history of medicine and science, the history of the state, and social and cultural histories that highlight how such a category was used in practice. The chosen chronological arc stretches from the early modern period into the twentieth century, focusing on North America and Europe, but also looking beyond. ###### [*Program and Conference page*](https://emworkshop.fas.harvard.edu/historicizing-calendar-age) ###### [*Keynote Lecture Poster*](https://emworkshop.fas.harvard.edu/sites/g/files/omnuum951/files/2026-04/Field%20Poster_Apr10.pdf) **Organizers:** Hannah Marcus, Ludwig Pelzl, and Ben Maldonado.
