Extension:DateDiff

The DateDiff extension adds a 'dates' parser function that returns a list of intermediary days.

Usage

A typical use case are events in a semantic setup that span multiple days. In order to have the events appear on all days on a calendar provided by the Semantic Result Formats extension, you would use something like:

{{#ifeq: {{{recurring}}} | no | {{#arraymap: {{#dates: | StartDate={{{from}}} | EndDate={{{till}}} }}|,|@@@@|[[Has date::@@@@| ]]| }} }}

Installation

• Copy the code into files and extract the tarball in your extensions/ folder. It should generate a new folder called DateDiff directly inside your extensions/ folder.
• Add the following code at the bottom of your LocalSettings.php:

require_once "$IP/extensions/DateDiff/DateDiff.php";

• Done! Navigate to "Special:Version" on your wiki to verify that the extension is successfully installed.
