			laenk_date.year

			laenk_date.week (calls the week number within the whole year)
			laenk_date.mweek (calls the week number within the month as values 1–5)
			laenk_date.wday (calls the day of the week as values 1–6)
			
			These will always return a number. You can use this number to index your language data using data["lfv"]["months"][laenk_date.month], for example, or just use it on its own when formatting dates with numbers.

					-- PUT YOUR CODE TO FORMAT THE DATE HERE
				end
				
		You can use any word as a parameter. Just set up an if parameters[" ... "] then … with a word or phrase you want to use as a calling argument and it will be recognised. For example, Rad has a "mod" parameter, which is only mentioned in the if statements below, and then I can call it in the {{date}} template.
