Note that the year is optional. The following give the ''n''th ''w''-day of month ''m'' this year.
* <code><nowiki>{{Weekday in month||</nowiki></code>''m''<code>|</code>''w''<code>|</code>''n''<code>}}</code>
* <code><nowiki>{{Weekday in month|</nowiki></code>''n''<code>|</code>''w''<code>|</code>''m''<code>}}</code>

=== Parameters ===
{|class=wikitable

==Calculation==
The template then gives ''j'', the day of the month, as calculated by the following formulae.

:''j'' = 7×''n'' − 6 + (''w'' − ''w<sub>1</sub>'') mod 7 (for positive ''n'')

:''j'' = ''t'' + 7×(''n'' + 1) − (''w<sub>t</sub>'' − ''w'') mod 7 (for negative ''n'')

Where ''t'' is the last day of the month, ''w<sub>t</sub>'' is the non-ISO weekday number of the last day of the month, ''w<sub>1</sub>'' is the non-ISO weekday number of the first day of the month and ''n'' and ''w'' are as defined above.
