If you are taking about the years from 1800 to 1899, then it is a plural, so it is the 1800s. If you are talking about something belonging to the year 1800, then it is a possessive and so it uses an apostrophe. For example, you could have something like: 1800's summer was very good. It is very common to see people use the apostrophe in the wrong way when talking about years that way.

It can't. An apostrophe should never be used to form a plural. This is grammatically incorrect, though unfortunately common. An apostrophe is commonly, but erroneously, used in numbers such as calendar decades or centuries instead of using the correct form, e.g. 1800s or the 1970s. Apostrophes should only be used for possessive nouns (but not pronouns), e.g. The cat's food dish or for omissions in contractions, e.g. it's meaning it is. In some situations it is acceptable to use an apostrophe to clarify a plural. For example, "Make sure you dot all the i's and cross all the t's". This, however, is not an established rule. If in doubt, leave the apostrophe out.
