hello,

day of wek usage of 1/2 does not work. It should be used every 2 weeks but it raises an InvalidArgumentException.... is the use of 1/2 for day of week not recommended? greets p

I don't think it's possible to get cron to run something every 2 weeks. You could try the following:

  1. Schedule it for every 14 days
  2. Create an @weekly schedule and test in the file the last time the action was run. If it hasn't been two weeks, then exit.
