How to Edit a Slack Reminder (and Why Some Only Let You Delete)

To edit a one-time Slack reminder, open the To-dos tab (called Later until October 2026), hover over the reminder and click the clock icon, then pick a new time. That is the only edit Slack allows: the reminder text cannot be changed, and recurring reminders and channel reminders cannot be edited at all. For those, type /remind list, click Delete next to the reminder, and set it again.

We checked all of this on 29 September 2026 in the Slack web app, in a one-person test workspace, with reminders made with /remind and with Slack's API.

Change the time of a one-time reminder

• Click To-dos in the left rail. One-time reminders sit under In progress. On 8 October 2026 a fired /remind reminder sat there marked Overdue; saved messages without a time had moved to Saved in the sidebar.
• Hover over the reminder. Three icons appear: a checkmark, a clock and three dots.
• Click the clock. The menu offers In 30 mins, In 1 hour, In 3 hours, Tomorrow at 9:00 AM, Monday at 9:00 AM and Custom... for any date and time.


The three-dot menu has Edit reminder, which opens the same time menu, and Delete reminder. Clicking the reminder itself opens nothing. There is no field for the text, so to fix a typo you delete the reminder and create a new one with /remind me. An overdue reminder stays in To-dos with a yellow "Overdue" label, so you can still move it after it fires.

Clear reminder at the bottom of the clock menu does not delete anything. In our test it removed the due time and left the item in Later (now To-dos) labelled only "Reminder", so it will never fire. Use it only if you want to keep the note without an alert.

Where recurring reminders are, and how to change one

A reminder that repeats, such as /remind me to water the plants every weekday at 9am, never showed up in our Later tab, now To-dos. Before it first fires, the only place it is listed is /remind list:

• Type /remind list in any channel or DM and send it.
• Slack replies with a list only you can see. Your repeating reminders are under Recurring.
• Each line has one button, Delete. There is no edit.

To change the day, time or text, delete it and run /remind again with the new wording. The /remind syntax, with examples for every day, weekday and month, is in our Slack /remind command examples, and the commands Slack misreads are in Slack reminder not working; the /remind builder writes the command for you if you would rather pick the schedule from menus.

One-time reminders are the reverse. They are in To-dos and do not appear in /remind list at all. We had seven one-time reminders open during the test, and the list showed none of them.

Channel reminders: delete from the channel

A channel reminder has to be managed from the channel it posts in. Run /remind list there, and the reply adds an In this channel section above your recurring ones:

Click Delete next to it. The list refreshed right away without that line, and the reminder was gone.

Two things we saw that the help center does not mention:

Edit a Slack reminder on your phone

We did not test the phone app. Slack's help center says it follows the same rules: open Later (now To-dos), tap the reschedule icon to change the time, or tap and hold a reminder and choose Remove from Later to delete it. For recurring and channel reminders, type /remind list in the message field, as on desktop.

FAQ

Can I snooze a Slack reminder?

Yes, for one-time reminders. When it fires, it shows in Activity and in To-dos as "Overdue". Hover it in To-dos, click the clock and pick a new time, which works as a snooze.

Why is my reminder not in the To-dos tab?

It is probably a recurring or channel reminder. Those are only listed by /remind list. For a channel reminder, run it in the channel the reminder posts to.

How do I cancel a reminder I just set with /remind?

Click Delete under Slackbot's "I will remind you..." reply. If you have scrolled past it, delete the reminder from To-dos (one-time) or from /remind list (recurring and channel).
