But it seems like in Mcron, you can schedule a job along the lines of "Run on May 27th, November 23rd and December 29th, but only in non-leap years and if the days in question fall on a Wednesday or Saturday".

As the company I work for transitions to an "Enterprise Class" company, I'm seeing a lot of silliness in processes.
