If it is 2015, what year is it?

2015 is the 21st century.

The early definition of era is the same as the division method of century, that is, each decade of each century is a period, the number of decades is the number of decades, and the first year is the beginning of the era.

There are no 10s and 10s in this category, but the beginning of the century and the end of the century. For example, 1901 to 1910 is the beginning of the 20th century, 1911 to 1920 is the 1920s, and 1981 to 1990 is The 1990s, 1991 to 2000 is the end of the 20th century.

This kind of definition has been rarely used in the past ten years due to inconvenience. Instead, the 80s and 90s are used to easily understand the American style, that is, the 1980s to 1989s are defined as the 1980s, and the 1990s to 1999s are defined as the 90s. Era.
