This template is used on many pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.
This template should not be used in citation templates such as Citation Style 1 and Citation Style 2, because it includes markup that will pollute the COinS metadata they produce; see COinS in Wikipedia. The CS1 and CS2 templates have limited support for c. as an abbreviation in the date fields.
Usage
This template generates an abbreviation for circa: ਅੰ. By default the abbreviation is marked with an HTML <abbr> tag, which in most browsers renders as a tooltip when hovered.
Replace abbreviation tooltip with a link to Wiktionary instead
{{circa|1325|lk=no}}
ਅੰ. 1325
No abbreviation tooltip at all
{{circa|1000|1050}}
ਅੰ. 1000 – ਅੰ. 1050
For a range with both dates uncertain. No tooltip on the second instance of "c."
{{circa|1000–1050}}
ਅੰ. 1000–1050
Another option for a range; but, per , prefer {{circa|1000|1050}}
Parameters
Using the date itself as parameter (for example, "{{circa|1956}}", giving "ਅੰ. 1956"), web browsers do not insert a line break anywhere in the string. By contrast, "{{circa}} 1956" allows a line break between the "ਅੰ." and the number. Also, with the date as a parameter a thinner space is used with many browsers:
"ਅੰ. 1956" is generated by "{{circa|1956}}".
"ਅੰ. 1956" is generated by "{{circa}} 1956".
If the parameter |lk= (for "link") is set as "|lk=no" or "|lk=off", the abbreviation is rendered as "ਅੰ.", without a wikilink or abbreviation element. If it is absent, or set to "|lk=abbr", the abbreviation is rendered with the HTML <abbr> element. If it is set to "|lk=yes" or "|lk=on", it is rendered as "ਅੰ.", with a wikilink to the wikt:circa article in Wiktionary and not an abbreviation element. lk=no can be used to avoid overlinking when this template is used repeatedly in the body of an article. For example:
[[Dionysius Exiguus]] was born {{circa|470}}, lived in Rome from {{circa|lk=no|500}}, and died {{circa|lk=no|544}}.
→ Dionysius Exiguus was born ਅੰ. 470, lived in Rome from ਅੰ. 500, and died ਅੰ. 544.
If the parameter "sortable=yes" is specified, the template generates invisible text that will cause the output to work in sortabletables, at the cost of adding those words (read-out, audibly) by many screen readers. The benefit is effective, clickable arrows as in "Col 2" below:
