What is the difference between Century and Era?

The difference between century and era

is that “century” is a period of 100 consecutive years; often specifically a numbered period with conventional start and end dates, e.g., the twentieth century, which stretches from 1901 through 2000, or 1900 through 1999. The first century AD was from 1 to 100 and “era” is a time period of indeterminate length, generally more than one year.
