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:

• Custom 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.

Set 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]

Remind a person or a channel

Set reminders for other members on your team or for a specific channel. Keep in mind that if you set a channel reminder, all members in that channel will be able to see it.

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

Remember: for private channel reminders, don't forget to add the # sign in front of the exact spelling of the private channel's name.

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

Format a reminder

There are a number of ways to set a reminder at a specific time and date. If you don’t include a time of day, Slackbot will default to 9:00am on the day or date you choose.

📆  Time and date formats

The /remind slash command 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
  E.g. /remind me to "Call Rieko" in 25 minutes
  
  
• Specific time: at 8:55pm (12-hour clock), at 16:00 (24-hour clock), at midnight
  E.g. /remind @lima "Lunch time!" at 12:30pm 
  
  
• Specific date: on January 1, on 8 Feb, on 11/30/2018 (MM/DD/YYYY)
  E.g. /remind #management "Send annual salary review report" on July 15 
  
  
• Specific days: every weekday, every Monday, Wednesday and Friday
  E.g. /remind #design "Design critique meeting" every Thursday
  
  
• Specific days, alternating weeks: every other Tuesday
  E.g. /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 on Mondays to update the team meeting agenda
• /remind #channel-name at 11:00 every Tuesday to attend the team meeting 
• /remind me every January 25 to schedule annual reviews 

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:

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 a reminder

Type the /remind list slash command and send it anywhere in Slack to view a list of your upcoming, past, or incomplete reminders. To view and manage reminders for a particular channel, use the /remind list slash command in that channel.

• Delete 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.
• If you need to modify reminders you've set, delete the existing ones and create new ones with the updated information.

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

Troubleshooting

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 it in a message back to you. Carefully review the time and date. If it seems wrong, it may be that your Slack profile’s time zone setting is different from the system time on the device you’re using.
  
  
• Follow the reminder instructions 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 recommend following the time and date format of English reminders if you’re having trouble.
