How to block time in your schedule
YCBM checks your linked calendar for any existing conflicts, and blocks those times from being booked. If there are times or days you don't want to be available for booking, you can block out that time directly on your linked calendar.
Blocking time in your day
Blocking an entire day or week
Blocking the same time period every day
Blocking different periods of time each week
Block time in your day
Any existing event in your calendar set to busy will block your availability from showing up on YouCanBookMe. To block off any time, create a busy event in your linked calendar. When you have blocked your time, YCBM will show you as unavailable for bookings.

Block an entire day or week
To block off an entire day or a week in your calendar from being booked, you can add an all-day event to your Google or Outlook calendar. Make sure you add this to the same calendar YCBM is looking to for conflicts, and make sure to set the all-day event to "busy" - these type of events usually revert to "free."
If you are accepting Group Bookings per timeslot, include YCBM-OVERRIDE-UNITS in the event title to fully block that time period from being booked.
Step by step:

Block the same time period every day
The break feature in your YCBM settings will remove times from your booking page when you don't want to be booked. You can add a break under Times & Availability > Availability.
Block different periods of time each week
If you need more flexibility over your schedule, or don't want to offer all of the available times on your calendar for booking Calendar Managed Availability is the solution for you. Instead of blocking off times you're not available, you'll create blocks of time on your calendar that will indicate you are available for booking. You can manage the availability you offer to your clients directly on your linked calendar, instead of adjusting settings within YCBM.
