Hi Fábio,
first of all you create an inverse holiday calendar (== business days calendar) using the interval editor.
Like
![holidays.png](https://groups.google.com/group/schedulix/attach/85483207c8475/holidays.png?part=0.1&view=1)
Then you use this calendar as a filter, like in
![daily_at_5.png](https://groups.google.com/group/schedulix/attach/85483207c8475/daily_at_5.png?part=0.2&view=1)
Note: I've defined November 30th (tomorrow) as a holiday and this date is indeed missing from the list.
HTH
Ronald
