I would like the due date on a card to move on by 12 weeks every day.

[Rick Notley]

I would like to setup a rule that changes the date on a card to be 12 weeks away every day (or 84 days if needs to be days not weeks)

We have an events calendar so want an ongoing reminder of the date in 12 weeks time for planning purposes.

@Rick Notley  you can create a scheduled automation

Action will be edit issue field

Field: due date

Value: 

{{issue.duedate.plusDays(84)}}

(This will move existing due date 84 days away.

if you want the date to set 84days from the moment when automation is triggered, you can use:

{{now.plusDays(84)}}

Beside using days you can use Hours, Weeks...

The synthax is the same, just replace "Days" with Weeks and change number

thanks, not sure how to implement this, what do I need to do to set this up?
