Currently, when utilizing a dashboard, there is no way to use the comparison function to compare a period of time accurately if the end of your comparison falls on Feb 29.

For instance, if looking to compare the gift amount raised for Jan - Feb 2021, there is no way to have the dashboard insight compare the same period last year, as Feb 2020 was a leap year (with Feb 29), which can not be entered under 2021.

The only alternative is to run two separate insights, or to run the report to include Mar 1.
