Ability to change the completed date of a task

Hi, is there a way to change the completed date of a task after that task has been marked as completed?

Not directly. You can unmark the task as completed, then mark it complete again and it will set the completed date to today’s date. That’s really the only way to alter the completed date I know of.


Hi Patrick, it’s a no if you want to change the finished date to in the past, we all forget to hit the completed button sometimes, and it disturbs reporting.

I have created custom fields to do this, it’s still not a perfect solution as the custom fields are text as date format does not exist.


“does not exist yet…” :slight_smile:

Asana has let us know that date-type custom fields (and a few other new custom field types) are coming; they’re just not quite here yet.


Seems a major shortcoming not to be able to mark the date I actually completed the task (date in past) - a deal-breaking kind of major IMO.


Just want to add my support for this capacity. There is this thread here that I believe requests this feature but only has 3 votes so far. Very hard to assess staff productivity or put together accurate reports if completion dates are solely determined by the moment that the check button is clicked. Need to be able to backfill completed tasks in a way that does not break the flow of the real timeline.



As well as using Asana for Project management, my team uses the tool for keeping track of important projects in the lifecycle of a project. Sometimes, even though a team-member completes a task before the due date, they forget to mark it as complete.

Is there a way to retroactively change the completion date to match actual completion dates for tasks that won’t always be crossed off on time?

Welcome :wave:
Not yet, this is something that has been asked before I think, I’ll ask the moderation team to merge your thread with the other one.

Thanks @Bastien_Siebman and welcome @Tristan_Thomas_Sagge :wave:t3:

We already have a #productfeedback thread on this topic so I’ve gone ahead and merged this thread with Is there a way to change the completed date of a task? to gatehr all feedback in one place :slight_smile:

I was surprised to find that you can’t back-date a completion date to when a task was actually completed. People mentioned adding custom fields an such to address this, but we should be able to modify the completion date of the task, not a custom field that we have to create. Has this been corrected yet? Thank you.

Hi @Eric_Kappmeier and welcome to the forum!

This behavior is still in effect; not possible to change the completed date of a task. If you haven’t yet, be sure to add your vote for this enhancement at the top of the page.

Hello. Is it possible to change the completed date? So if someone forgot to mark a job as complete, would I be able to manually change it to show the correct date is was completed on?

Hi @perfectgardens, thanks for reaching out!

As it stands, it’s currently not possible to change the date a task was mark complete. We have a request in our #productfeedback category for this feature so I have gone ahead and merge your post with the main thread to centralize feedback. We’ll update the main thread once we have any updates!
