Automatic & retrospective deadlines


I would have liked to know if it was possible to have automatic and retrospective deadlines on Trello.

My process has several steps (represented by a column (with several tasks/cases) = one step) and each of these steps must be completed in a fixed number of days.

All my deadlines depend on a single date.

Example: Meeting date = 05/04/2021
Step 1 = needs to be completed 60 days before the date of the meeting
Step 2 = needs to be completed 30 days before the date of the meeting

Is there an add-on or a way to make this please?

Thank you in advance!

A similar requirement appeared on this community a few days ago but it was on checklist item. For it to work, in at least a generic fashion, is to make first assumption that the cards are in the correct sequence behind the trigger card. The endpoint is given a series of numbers representing days from due date. Given that the endpoint had to operate with Butler and need to update the cards that it is given the authorisation ie api key and token in some way either through the call or registered with the endpoint. I have built a add-on for that but have not coded the module. I am fairly confide that it can be done.

This is quick demo of what can be achieved.


Current status : the program is completed. It is matter of deciding on the delivery. Currently, it is creating new cards instead of updating existing ones. It allows for the cards to be prepared and moved by Butler by way of Butler "collect cards" action ...etc

An improved version

It updates existing cards for all cards whose pos is greater than the trigger card and it uses a CF Number  "Days_Before" to determine the due date to set for the card.
