Usage sửa

This template can be used in other templates to check or analyse a year, whether Common Era (CE) or Before Common Era (BCE).

{{is year|input=|function=}}

The template can be used without named parameters as well. The most basic usage is:

{{is year|}}

Input sửa

The input must be in the form of YYYY or YYYY BCE. The maximum value is 2100 and the minimum value is 2000 BCE. As there is no year 0 (zero), the input 0 is inappropriate.

Function sửa

The function must be one of the numbers in this table. This parameter is optional. If not set, function 0 is the default.

Number	Function	Output
0	Basic	Returns the numeric part of the input only.
1	Decade	Returns the decade corresponding to this year.
2	Century	Returns the century corresponding to this year.
3	Logic	Returns a 1 (one) if the input is a recognised year.
4	Common Era	Returns 1 (one) for years in the Common Era/Anno Domini. Returns -1 (minus one) for years Before Common Era.

If the input is not a recognised year, this template will return FALSE; unless function 3 or function 4 is selected, in which case it will return 0 (zero).
