It’s About Time: Untangling Everything You Need to Know About Time

Two friends, Jacob and Lily, serve as guides to timekeeping and measurements of time, from one second (“just a tiny little instant”) to a full century. Estellon explains each concept clearly, while also invoking alternate ways to think about them; thus, an hour is both “60 minutes” and the amount of time needed to bake a pound cake (“It took one whole hour to make it. And it will only take five minutes to eat it!”). Explanations of how to tell time on a clock, how hours create days (and weeks, months, and years) also appear, with Estellon’s cheerful cartooning offering both entertainment and visual support for each topic.
