Determine week number and day of week?

[David Loszewski]

Is there a way to determine, with jira for automation or some other tool, what week number and day of the week a date and time field is in?  For example, if I have:

November 16, 2020

I want to be know that it's the 3rd Monday of the month.  

That way I can basically create a recurring schedule and automatically change the date/time field to December 21, 2020.

You can utilize Power Scripts for Jira Cloud and its dayOfWeek function. You may need to convert the date into the format acceptable by the function, should be able to do with formatDate.

Is there a weekOfMonth option?
