Title: Minute as a time unit for scheduled reminders
ThreadText: # Minute as a time unit for scheduled reminders
  
  (Asked by: username_0 on 2020-12-11)
  
  Right now the smallest unit is the hour, so I can schedule a reminder 1 hour before or after something.
  
  What do I do if I wanted to send a reminder 30 minutes before something? Is this possible right now?
  
  If not, how difficult would it be to make an extension that would introduce **minute** as a time unit for reminders? Would this be difficult to achieve? Are there any clever workarounds?

  It's a legitimate question although even if you could do it per minute, you'd then have to have cron run every minute, which is technically possible but might be a bit excessive.
  
  If you're talking about reminders for activity assignees, an alternative might be to turn on the setting at Administer - Customize - Display Prefs - Include ICal Invite to Activity Assignees. Then they can put it in their calendar and they can set it to remind them as desired.
