Calculate Century

Calculator for the years of a century and its fractions. If only the number of a century is entered, then a span of one hundred years will be shown. Also, a numerator and a fraction (half, third, fourth, fifth) can be entered, like second half, to show the according span. At input errors, like fourth third, the output will be empty. At thirds, the years can't be divided equally, here the second third has 34 years, the other two have 33 years each. BCE means before common era.

Examples: the second quarter of the 19. century was from 1826 to 1850. The first half of the first pre-Christian century was 100 - 49 BCE.
