Hey,

Yes you can use an expression for the timer definitions. Have a look at [https://www.flowable.org/docs/userguide/index.html#timerEventDefinitions](https://www.flowable.org/docs/userguide/index.html#timerEventDefinitions) for more information.

Keep in mind that when using an expression it will be evaluated when the task is created.

Cheers,  
Filip
