Cách sử dụng
The expression "year on year" is used to compare a certain statistic or trend from one year to the same time period in the previous year. For example, if a company's sales increased by 10% year on year, it means that their sales in the current year increased by 10% compared to their sales in the previous year during the same time period. This expression is often used in business and finance contexts to evaluate performance over time.
