Why do we call centuries by one century higher? A century is 100 years starting with 1 and ending with 100. This was the first century AD (or CE). Next comes year 101, the first year of the second century. This ended with the year 200.After that comes 201, the first year of the third century. This ended with the year 300.est Answer: If we start at the year zero (there wasn't one, but humour me), the first century runs from 1 - 100, the second century from 101 - 200, the 15th from 1401 - 1500 etc.
