Cách sử dụng
A century is a period of 100 years. It is used to talk about time that has passed and to refer to a hundred years in history. For example, the 19th century refers to the period of years from 1801 to 1900. Centuries are also used to talk about future time in certain contexts, such as when predicting how technology or society might change over the next century. It is important to note that the word 'century' refers to a very specific amount of time, and should not be confused with 'decade' (10 years) or 'millennium' (1,000 years).
