I need to query for the total number of issues created for the previous month. For example, if I want to know the total new issues created during the month of August and it is already September, how can I do this with a function so I don't have to modify the query every time it is run? I can't use startOfMonth() or endOfMonth() since it will return the issues created in October instead of September unless there is a way to use a set back that will give me the previous month.
