Time Conditions already enabled you to make Output Players trigger your content-, or automations activate your triggers when you planned them. This recurring pattern makes it for example possible to automate the visibility of a specific Visual on an Output or only activate the Studio (Automation) only on Monday and Tuesday in the month september.
This feature has been upgraded with start- and end- dates of your time planning. Which only enable the recurring pattern (described above) from the startdate and until the enddate.
