This template returns the number of days between two dates. Dates may be input either as full dates or as year, month and day.

==Usage==
====Full dates====
To use, type:
:{|
|-
|<code><nowiki>{{age in days|date1|date2}}</nowiki></code>&nbsp;||(number of days between dates 1 and 2),
|-
|<code><nowiki>{{age in days|date1}}</nowiki></code>            ||(number of days since date 1) or
|-
|<code><nowiki>{{age in days||date2}}</nowiki></code>           ||(number of days until date 2)
|}

Examples:
:{|
|-
|<code><nowiki>{{age in days|19 Aug 2008|4 Sep 2010}}</nowiki></code>            ||gives {{age in days|19 Aug 2008|4 Sep 2010}}
|-
|<code><nowiki>{{age in days|27 May 2002}}</nowiki></code>                       ||gives {{age in days|27 May 2002}}
|-
|<code><nowiki>{{age in days||{{#time:j M Y|+ 15 months}}}}</nowiki></code>&nbsp;||gives {{age in days||{{#time:j M Y|+ 15 months}}}}
|}

====Year, month and day====
To use, type:
:{|
|-
|<code><nowiki>{{age in days|year1|month1|day1|year2|month2|day2}}</nowiki></code>&nbsp;||(number of days between dates 1 and 2),
|-
|<code><nowiki>{{age in days|year1|month1|day1}}</nowiki></code>                         ||(number of days since date 1) or
|-
|<code><nowiki>{{age in days||||year2|month2|day2}}</nowiki></code>                      ||(number of day until date 2)
|}

Or with named parameters:
:{|
|-
|<code><nowiki>{{age in days|month1= |day1= |year1= |month2= |day2= | year2= }}</nowiki></code>&nbsp;||(number of days between dates 1 and 2),
|-
|<code><nowiki>{{age in days|month1= |day1= |year1= }}</nowiki></code>                               ||(number of days since date 1) or
|-
|<code><nowiki>{{age in days|month2= |day2= | year2= }}</nowiki></code>                              ||(number of day until date 2)
|}

Examples:
{|
|-
|<code><nowiki>{{age in days|2007|5|24|2008|4|23}}</nowiki></code>&nbsp;||gives {{age in days|2007|5|24|2008|4|23}}
|-
|<code><nowiki>{{age in days|2007|5|24}}</nowiki></code>                ||gives {{age in days|2007|5|24}}
|}

===Sorting===
By adding {{para|sortable|on}} a sort key will be added to the output for use in sortable tables.

===Formatting===
Three styles of formatting are possible.
:{|
|-
|{{para|format|raw}}         ||gives unformatted numbers with hyphens as minus signs<ref>Negative days will occur if the first date is after the second.</ref> (for use in further calculations).
|-
|{{para|format|commas}}&nbsp;||gives numbers formatted with commas and true minus signs.
|}

For reasons of retrospective compatibility, the default when inputting dates as year, month and day is {{para|format|raw}}; however when inputting dates in full it is {{para|format|commas}}.

:Note
{{Reflist}}

===Showing the unit===
The default is not to show units.  To show the unit ("day", days" or "d") use {{para|show unit}}.

:{|
|-
|{{para|show unit|abbr}}&nbsp;||adds "d" after the number of days.
|-
|{{para|show unit|full}}      ||adds "day" or "days" after the number of days as appropriate.
|}
