Set a reminder

Busy as a bee or maybe feeling a little forgetful? You can send yourself or other members a reminder for anything: important meetings, to-do items, even motivational messages!

There are two ways to set a reminder in Slack on either your desktop or mobile:

  • Customised reminders using /remind slash command
    Use the /remind slash command anywhere in Slack and Slackbot will send the reminder for you.
  • Message reminders
    When you want to follow up on a message in Slack, choose from a preset menu of time options for Slackbot to notify you.

Use Slack in a different language? The functionality of this feature may vary depending on your language preference. Use the English /remind slash command and formatting suggested in this article if you’re stuck. Or type /remind and press Enter for a menu of preset options.

Add a custom reminder

In the message field, type the /remind slash command and you’ll see a template of how to format your reminder: /remind [@someone or #channel] [what] [when]

Here are some examples:

Remind a person or a channel

  Slash command [@someone or #channel] [What] [When]
To remind yourself /remind me Drink water Every day 
To remind a member  /remind @lima Submit report 30 May
To remind a channel  /remind #design Join the meeting Monday

Remember: To set a reminder in a private channel, type /remind #[private channel name], followed by your reminder. Don’t forget to add the # symbol in front of the exact spelling of the private channel’s name.

Note: Multi- and single-channel guests can’t set reminders for other members or channels in a workspace.

Format a reminder

There are multiple ways to set a reminder for yourself, a member or a whole channel at a specific time and date. If you don’t include a time of day, Slackbot will send the reminder at 09:00 on the day or date you choose.

📆  Time and date formats

To fill in the [when] portion of the /remind slash command, Slackbot understands a number of time and date formats – various examples are shown in bold below:

  • Increments of time: in 10 seconds, in 17 minutes, in 1 hour or in 2.5 hours
    Example: /remind me “Call Rieko” in 25 minutes

  • Specific time: at 8.55 pm (12-hour clock), at 16:00 (24-hour clock), at midnight
    Example: /remind @lima “Lunch time!” at 12:30

  • Specific date: on 1 January, on 8 Feb, on 30/11/2018 (DD/MM/YYYY)
    Example: /remind #management “Send annual salary review report” on 15 July

  • Specific days: every weekday, every Monday, Wednesday and Friday
    Example: /remind #design “Design critique meeting” every Thursday

  • Specific days, alternating weeks: every other Tuesday
    Example: /remind me “Physiotherapy after work” every other Wednesday

Tip: Use quotation marks to separate your reminder message from the time and/or date that you want the reminder to occur. 

🌎  Time zones

For teammates who are in a different time zone, you need to take their time zone into account when setting the reminder. For example, if you’re in Greenwich Mean Time (GMT) and need to remind a teammate who’s in Central European Time (CET) at 12:00 their time, you need to set the reminder for 11:00 your time.

🔂  Recurring reminders

You can set recurring reminders in a number of ways too. Here are some ways to format the [when] portion of a recurring reminder for you or a channel:

  • /remind me to update the team meeting agenda on Mondays
  • /remind #channel-name to attend the team meeting at 11:00 every Tuesday
  • /remind me to schedule annual reviews every 25 January

Note: You can’t set recurring reminders for other members.

Message reminders

You can have Slackbot remind you about a message or file that was sent in Slack.

Here’s how:




  1. Click the More actions icon on a message or file.
  2. Hover over Remind me about this, then choose a time frame from the list.
  1. Touch and hold on a message or file.
  2. Tap Remind me.
  3. Tap the time frame you would like to be reminded in.
  1. Touch and hold on a message or file.
  2. Tap Remind me.
  3. Tap the time frame you would like to be reminded in.

Manage your reminders

⏰  Snooze a reminder

If you’re not ready to act on your reminder, use the drop-down menu in the reminder message to reschedule: in 20 minutes, 1 hour or tomorrow at 09:00.

Note: Channel reminders can’t be snoozed.

✅  Delete or mark as complete

In your Slackbot DM, type the /remind list slash command to view a list of your own upcoming, past or incomplete reminders. To view and manage reminders for a particular channel, use the /remind list slash command in that channel.

  • Delete any of the reminders you no longer need or created by mistake.
  • Mark reminders as Complete and simply click View completed reminders to see a full list.

Bear in mind: Recurring reminders cannot be completed, only deleted.


We understand that reminders can be tricky sometimes – especially when you’re using the Slack app in a different language.

Type the /remind help slash command for a recap on how to format your reminders. Alternatively, here are some things that can help:

  • Check your time zone
    Every time you schedule a reminder, Slackbot will confirm and repeat it back to you. Carefully review the time and date. If it seems wrong, it might be that your Slack profile’s time zone setting is different from the system time on the device you’re using.

    Check the system time on your desktop or mobile device or change your time zone in Slack. Once the settings are updated, don’t forget to create the reminder again.

  • Follow the reminder instructions/format for English
    The functionality of this feature may vary depending on the language preference you have set in Slack. We’re working hard to improve setting custom reminders in Slack.

    In the meantime, you can still create the reminder in your language, but we do recommend following the time and date format of English reminders if you’re having trouble.
