Hi kathleen452.

While we're unable to create a comparison with different date ranges, I suggest finding a third-party software that can do this level of customization. You can find one in the QuickBooks Desktop Market Place. 

In the meantime, you can create a report per custom date range and combine them on one Excel sheet to better see the comparison.

I can see how helpful this option to you and to other users in this thread. I'll share this idea with our product development team, and you can also send them a suggestion. Just click on the Help menu and choose Send Feedback Online.

If you need anything else, please let us know.
