Summary:
Time is measured in a variety of units, including seconds, hours, days, weeks, and decades. This practice began with the sundials of ancient Egypt, but we still use clocks and calendars today to keep track of our time. This volume guides readers through measuring time, figuring out time zones, and learning about classic and modern timepieces.
