If you click on a day cell in the JEvents Calendar Module you will be redirected to a list of events for that particular day. If there is only one event on this day then it makes sense, on some sites, to redirect the visitor to the relevant event detail page. This template override allows you to do this.
Let us assume that you are using the extplus layout in JEvents then download this file:
extract it and upload it to:
templates/YOURTEMPLATE/html/com_jevents/extplus/day/ (creating any missing folders).
If using another layout then replace extplus with your layout name e.g. iconic.
And that should be it! any problems please do not hesitate to ask in the Forums
