用英语表述年号怎么说

In English, the term for a year number is "year." For example, you can say "2022 is the current year," or "I was born in 1999." You can also use ordinal numbers to indicate the position of a year in a sequence, such as "this is the first year of the new decade" (referring to 2020) or "the year 2021 is the second year of the new decade."
