In QGIS 3.2.3: I have a layer/Shapefile with a date field (type DATE) that comes from a joined table. I would like to symbolize the points which are older than 10 days (based on the current date) in another color than points which are younger than 10 days (based on the current date). It would also be possible not to display the younger points.

Is there a way to use the current date to make such visualisations? Maybe with a **rule based symbology**: I thought in using an expression with the **now() function**, which returns the current date and time and then remove 10 days from it, but couldn't get it going. Am I missing something?
