I would like to calculate the number of days between two dates. The first date is written in attribute table [YYYY-MM-DD] (creation date) and the second is today [now()]. The goal is, to get the age of every feature.
I need it as QGIS expression to create a virtual field.
date1 (attribute in table) - now() = age (as virt. field)

You can compute the duration between the two dates using the
age
function. Since it returns a timespan, you can then extract the number of days from it.
