This widget allows you to display a calendar

Created by Xopr

Using this widget

To insert this widget, use the following code: 

{{#widget:Calendar
|date=february 26 2011
|w=true
|hl.26 february 2011=blue
|hl.1 march 2011=red
|t.17 february 2011=First peek into ACKspace's new space
}}

This will give the following result:

Note:

  • all parameters are optional. If date is omitted, the current month will be displayed
  • you can highlight dates by using the hl parameter, followed by a dot and the date you want to highlight. Available colors are: red, green, blue, yellow, cyan and purple
  • you can also add titles per-day using the 't' parameter, followed by a dot and the date you want to highlight.
  • w (show week numbers) is optional

Copy to your site
