+ To convert a (Gregorian) date into the so called ymcd representation:
+ dcal 2012-03-04 -f "%Y-%m-%c-%w"
+ dcal 2012-03-01-Sun -i "%Y-%m-%c-%a"
+ where the ymcd representation means, the %c-th %w of the month in a
+ given year. This is useful if dates are specified like, the third
+ Thursday in May for instance.
