This is the documentation of JSU for Jira Server/Data Center. If you are using JSU on Jira Cloud, you can find the documentation here.
The 'Date Window' checks whether the value of one date field falls within the range/window of another date field. Note: The date checking is only one-way, i.e., it only looks forwards, not backwards. You must select the two date fields and the window period, when configuring the transition. For example: <screenshot> A workflow is configured so that the 'Close' transition has the 'Date Window' check. The 'Resolved Date' is checked using a window of 5 days with respect to the 'Created Date'. If the issue is resolved within five days of being created, a comment will be added with the text "Quick Win!". JSU supports many different field types; system fields, as well as custom fields. You should be aware, however, that not all field types or all combinations are supported. We have tried to cover the most important field types but we are continuously adding more and improving how different field types are supported. We recommend you test JSU with fields to see if it is compatible with your system. Our evaluation license provides you with a 30-day free trial. Description
