So basically I am trying to setup a sharepoint time off calendar that will only allow users select a range of time off during the same work week - Monday to Friday only. I have edited the calendar to remove Saturday and Sunday so if a user selects an event lasting more than a week in the date range, the calendar does not display correctly. That is to say since Saturday and Sunday have events the calendar gets broken. Please let me know how I can use formulas to make sure my users can only select a range during a single work week. Or if there is an efficient way to remove weekends from month view that still allows users to select more than a week without breaking the calendar, please let me know. Hopefully I have not confused you :)
Add a list item validation formula. (List Settings, Validation)
This makes several tests:
- Dates must be in the right order.
- Start Date day of week (Tuesday) must be less than End Date day of week (Thursday)
- The dates must be less than six days apart.
Both dates must not be on weekends.
=AND( [End Date] > [Start Date], WEEKDAY( [Start Date], 2 ) < WEEKDAY( [End Date], 2 ), [End Date] - [Start Date] < 6, NOT( OR( WEEKDAY( [Start Date], 2 )=6, WEEKDAY([Start Date],2)=7 ) ), NOT( OR( WEEKDAY( [End Date], 2 )=6, WEEKDAY([End Date],2)=7 ) ) )
