Aspects of modularity for Calabi-Yau threefolds from physics

We give an overview of some mostly conjectural aspects of modularity for Calabi-Yau threefolds originating in physics. We focus on one parameter families of hypergeometric type and give computational results in terms of classical modular forms. This is based on work with K. Boenisch, A. Klemm, and D. Zagier, 2203.09426.
