Weeks and days are measures of time - how many more can you think of?
There are plenty of devices used to measure time. Watches and clocks are two of the familiar ones. Did you know a sundial also tells the time? And if you want to boil an egg making sure the yolk is still runny, what do you use? An egg-timer! You may not have heard of candle clocks or water clocks, but candle clocks go back thousands of years!
