You can set calendar reminders for your team. This will automatically start a meeting so you can start an event a day before to end the next day and, in this way, show other people that your team is engaged and should only be contacted in emergencies.
You can set dates to the start of the month or the end without having to worry about exact dates. Just remember to set your calendar for workdays.
Click on the event in your calendar to Join or click Join on any reminders to receive before the meeting.
