साचा:Is year/doc

विकिस्रोत कडून

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|}}

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.

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).
