Time window for every other monday
I have a requirement to create a time window which opens every alternate monday's. For Eg. If 1st of the month is monday and time window is open, then the next open period must be after 14 days. This time window has to be used as a precondition on the job with in a chain. I created one by hard coding the dates manually, but trying to find a way to automate this than manually maintain the time window by adding dates to it. Please help.
