Adding a date to the CLOSED tag in emacs org mode

Question

I recently started using emacs org-mode to support my TODO lists. I used it for a long time. Then I was able to automatically add the date when moving the task from TODO to the DONE tag, adding CLOSED: to the DONE label.

However, I forgot how to do it. Can someone help me tell how to add a CLOSED tag. in org mode

Answer 1

This can be done by setting the following variable (see Org Manual for more information and further customization if desired).

(setq org-log-done 'time)
