What century is the year 1492 CE in?

1492 CE is the 15th century. This is because just like there was no year "0," there was no 0th century. 01-100 CE is the first century, 101-200 is the second, and so on. A common misconception is that the century ticks from one to the next on the transition of years from '99 to '00. Since there was no year "0," the century mark actually changes from '00 to '01.
