The Egyptians used the period of daylight to measure time. Today, we use the hour as our unit of time most often. Each day lasts around 24 hours and each period of daylight (4 minutes, 40 seconds) is called an “hour.” To measure intervals longer than a day, such as a month or year, you divide it into smaller units called days.
. The use of time has been around for a long time, and there are many theories as to why we use it. Some people believe that using time helps us organize our thoughts, while others think it is important because it gives us an idea of how much time has passed.
Whatever the reason, we have been using time for centuries and will continue to do so in the future.
