Minutes. Hours. Days. Weeks.
Humans have been keeping time for millennia. Often the guide for this timekeeping is the movement of the sun across the sky. Larger spans, such as seasons, are noted with changes in vegetation or behavior of wildlife.
More recently, humans have used clocks. Some are simple and practical. Do you remember the clock in your elementary classroom? Ours was round, with large black numbers and hands to mark the time to recess, lunch, and dismissal. Digital clocks are popular today. Some of them show hour, minute, and second in a large display.
Clocks can also be whimsical, showing the sense of humor or the interest of the creator and owner. Examples would be cartoon characters with moving arms, cuckoo clocks with a bird darting out to proclaim the hour, or a clock face mounted into a cross-cut section of wood.
The example below comes from a small town library.
