How to set a timer which activates ... days before set date

Hi @mohritz.

Please have a look at this solution to a related question

How to add days to a date variable in a service task

@solo812 try expression like this below: ${dateTime().withMillis(dueDateField.getTime()).plusDays(10).toDate()} Deploy this bpmn and test: DateCalculationProcess.bpmn (2.9 KB) [image] [image]

So the expression should be like this:

${dateTime().withMillis(arbeit_ab.getTime()).minusDays(28).toDate()}

Alternatively you could call a bean method via the expression and calculate the date in the code.
