## Date auto lock / unlock

Date auto lock and Date auto unlock are tools that allow you to lock or unlock any date range in one go and to exclude chosen dates from inside this range for a selected service or category.

In the Date Auto Lock example below, we have selected the Service 1 schedule, locked the dates from 05/01/2019 to 06/30/2019 and excluded 05/13/2019 and 06/17/2019.

If you would have liked to close only on Fridays from 05/01/2019 to 06/30/2019, you would have done as below:

To validate this selection with exclusions and effectively implement them in the selected schedule, click on Start.
