Explanation
A period is a length of time when something happens or lasts. It can be short or long, like a few minutes, hours, days, or years. For example, school has periods for different subjects, or history has periods like the Ice Age. A period can also be the punctuation mark (the dot at the end of a sentence), which tells the reader the sentence has finished. It is used to measure, organise, or mark time and events.
