A century is a period of 100 years. A decade is 10 years.* Historical periods are often defined as a century. However, because there was no 0th century, the century number is always 1 higher than the first two digits of the year number (e.g. 1950 is in the 20th century) except for years ending in 00, which are in the preceding century (1900 is in the 19th century with 1801-1899).
You may be referring to the way the 1900s were called the 20th century for example. First, the 1900s are slightly out of alignment with the 20th century which is why people confuse them. You are not referring to the same years. So the 1900s refers to 1900 to 1999 whereas the 20th century refers to 1901 to 2000. Both are correct in their own right in talking about the 1900s or talking about the 20th century, but they do not refer to the same years. The 19th century and the 1900s are completely different, as the 19th century was 1801 to 1900, so had only one year in common with the 1900s, namely the year 1900. The 20th century is the 20th group of 100 years, so it ended at 2000. If the century and the the digits they start with were the same, I.E. the 19th Century was the years 1900 to 1999, then by default the 1st Century would have to be the years 100 to 199. If that were the case, then what would the year 1 to 99 be called, the Zero Century? Also, it would only be 99 years, as there was no year zero. The first century was year 1 to year 100. It didn't start with year 100 or the mythical year zero. The 2nd century was the second group of 100 years, so from 101 to 200. We are now in the 21st century, which is the 21st group of 100 years, so it runs from 2001 to 2100. People will refer to 2000 to 2099 as the 2000s.

No - the years from 1801 to 1900 are the nineteenth century - the first century ran from the years 1 - 100.
The 19th century
False, the years 1700-1799 was the eighteenth century.
The years of the 19th century were 1801 to 1900.
1801 - 1900
Ususally taken as 1800 to 1899, but mathematical purists would say 1801 to 1900.
The 19th century was the years from 1801 to 1900. The 20th was the years from 1901 to 2000.
Original Answer: 1800's New Answer: The 19th Century was not a year. The 1st Century consisting of the years 1 - 100, ended at the end of the ONE hundredth year; so also, the 19th Century ended at the end of the NINETEEN hundredth year. In other words, the 19th Century consisted of the years 1801 - 1900 (inclusive).
19th!
1826 is in the 19th century, which runs from 1801 to 1900.
