This article explains how to create a rule that automatically shifts a date field with the number of days which another date field was modified by.

Example: We have two Date type fields that are initially set as: Field A: 01/Jul/23| Field B: 20/Jul/23 When the Field A is changed to 08/Jul/23, we want automation to shift Field B with 7 days and set it to 27/Jul/23.


Create an Automation rule as below:

  • Add "Field Value Changed" trigger for Field A.

  • Add "Edit Issue" action and set Field B with the following expression:

    1 {{issue.Field B.plusDays(fieldchange.from.toDate.diff(}}

    The automation rule will look like in the screenshot below:
