* param 1 is the year
* optional param 2 is the month
* optional param 3 is the day of the month
* optional named parameter alt=[text] is alternative display text (may include wiki markup)
* optional named parameter lc=on gives lower-case-first output displayed text ([A/a]s of [Start date] by default)
* optional named parameter nocat =on removes the category
