How to make all due dates dependent on one milestone

[Vijayshree Gupta]

I am using Kanban Board to track tasks of my project. I am looking to see if I can make all deadlines of few tasks dependent on 1 date (like of a milestone)

For example,

There is a milestone is on Nov 1. I want to make tasks deadlines dependent on this date. Something like:

Task 1: Due date Nov1 -15 days

Task 2: Due date Nov 1 - 7days.

By doing this, I want to achieve 2 things:

1) Easier to populate the dates for tasks.

2) If the milestones move ( earlier or later), it's easier to tweak the task due date. 

Is there any such feature in Jira Kanban Board ?

Hello @Vijayshree Gupta

Unfortunately, Jira does not have a ready-to-use functionality that provides you with a milestone where you can add values like "-7d" to set your due date, however, you can achieve something similar by using Smart values in Jira automation. Allow me to give you a practical example:

Let's suppose that you want issues labeled as "Final_check" to be configured with a due date 7 days before a specific "Milestone", while issues labeled as "Initial_check" to be configured with 15 days before the "Milestone". Supposing the milestone would be "2020-11-10", you can achieve this with the steps below:

1. Navigate to your project > Project Settings > Automation
2. Create a new rule following the template below, using the smart value {{[date].minus[Unit]([number])}}:
   

The same logic above can be applied to other fields, not necessarily "Labels". You can even configure a custom field to determine the milestone in your issues, configuring the rule to properly update the "Due date" when that field is changed. 

For more details about Automation rules and Smart values for date fields, you can check the documentation below:
