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
  E.g. /remind me 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 December 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

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:

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