how to set holiday in a global calendar in a FP project

Hello, thank you for this software, just wondering how to set August 15th as holiday in the global calendar. I created a new copy of default calendar, then clicked on August 15th the color changed, and when i check the planning there is no change,

expected, the planned days advance to one extra day considering this holiday..please help

thanks for reply, i looking at calendar for all only not any resource specific calendar.

Also i want to use only the fp project not administrative project

1. i clicked August 14 & 15th in the calendar (default)
2. Came back to the planning view, these dates shown in grey colour.
3. but my expectation was the task to skip these days as working days
means, if a task which supposed to end by 14th should advance to 16th

kindly let me know this feature is available in fp or not
