Template:Which calendar

Template documentation[view] [edit] [history] [purge]

Usage

The {{Which calendar}} template is a variant of {{Clarify}} to be used specifically when the clarification that is needed is the calendar in which a particular date is expressed.

At various times in modern history, multiple calendars were in use at the same time. Therefore, in an article on Russian history, a date such as "March 1, 1881" may be ambiguous: it might mean March 1 [O.S. March 13] 1881, or it might mean February 17 [O.S. March 1] 1881.

You may use either of the following formats:

{{which calendar|{{subst:DATE}}}}

or

{{which calendar|date=December 2025}}

This template will place articles into Category:Articles containing ambiguous dates.

To fix the issue, use the {{OldStyleDate}} template to clarify the meaning of the date:

{{OldStyleDate|March 1|1881|March 13}}

which produces

March 1 [O.S. March 13] 1881
