What was the year 28 years before the end of the 16th century?

The last year of the 16th century was 1600, not 1599 as some would incorrectly say. 1599 was the second last year of the 16th century. The year 1573 was the 28th last year before the end of the 16th century.


Why do the numbers not match the first numbers in the years?

You are referring to centuries. If you think about it, for any century we are in works from 1 to 100 years, with the last year being the number of that century. So 1 to 100 would have been the first century or first set of 100 years, 101 to 200 would be the second century and so on. We are now in the 21st century, the 21st set of 100 years, which is from 2001 to 2100. In 2100, 21 sets of 100 years will have been completed, so we are now during the 21st century even though all but the last year of it will start with '20'.You are referring to centuries.
