Template:Century

The following documentation is located at Template:Century/doc. [<Edit> Template:Century/doc]
[⧼Purge⧽ Template:Century]

The {{century}} date and time template returns the century in which the given year belongs, where the year defaults to local year of OEIS Wiki server. There was no year 0, since the ancient Greeks or Romans had no concept of zero. Thus the years 1 to 100 belong to century 1 (the 1st century AD,) ..., the years 1901 to 2000 belong to century 20 (the 20th century AD.) Conversely, the years -1 to -100 belong to century -1 (the 1st century BC,) ..., the years -1901 to -2000 belong to century -20 (the 20th century BC.)

Usage

{{century|year as a nonzero unformatted integer}}

or

{{century}} where year defaults to local year of OEIS Wiki server
