To achieve your goal, you have two options:
Option 1: Use Time Comparisons
- Set your date range to the most recent month (e.g., day 1-20 of the current month)
- Use the Compare to Past feature to compare against previous months
- This allows you to see multiple time periods side by side, though you'd need to manually ensure you're comparing the same day ranges
Option 2: Create Separate Reports
- Create individual reports for each month with the specific day 1-20 range
- Use the Fixed date range option for each
- Compare results across reports
Unfortunately, the knowledge sources don't show a built-in way to filter for "day 1-20 of each month for the last 4 months" as a single query. You may need to work with these workarounds or consider using the JQL API for more complex custom date filtering if you have access to it.
