Yes agree, we should add this.

That is possible in trunk, see docs for the d2:daysBetween function:

https://www.dhis2.org/doc/snapshot/en/user/html/ch30s03.html


FunctionArgumentsDescriptiond2:daysBetween(date, date)Produces the number
of days between two data elements/attributes of type date. The static date
format is 'yyyy-MM-dd'.

 An example expression that uses the "daysBetween" function looks like this:

d2:daysBetween(#{mCXR7u4kNBW.k8ja2Aif1Ae},'2015-06-01')


regards,

Lars
