Today it means

noun A period of one hundred consecutive years; often specifically a numbered period with conventional start and end dates, e.g., the twentieth century, which stretches from (strictly) 1901 through 2000, or (informally) 1900 through 1999. The first century AD was from 1 to 100.

Language periods are conventional ranges, not dates for this word.
