Hi alexism
This is also an approach we us in many (many !) projects ! The dim date can work in different flavors (for instance for the use case Vadim is writing about, I usually work with a "month label" instead of shifting dates to current year), but it usually needs some slight work on the date itself, hence selecting a dim date or working on selected date.
If you ant something more generic, that will work with any date, you can try the pastyear functions, or PREV function if you need more that tone year against the previous one.
Hope this helps !
Best, David.
