Currently, the default behavior is for Business Closures to be counted as Work Hours on tasks in the project entity record.

However, this behavior is very inconvenient for users.

Holidays are counted as Work Hours despite Business Closures, which prevents the correct calculation of Work Hours.

It is possible to make a resource a non-work day by assigning it a "vacation" in the "Work Hours" of a bookable resource, but I don't think this is a useful workaround since the task is assigned.

By applying Business Closures even on tasks in the project entity record, users can make more convenient and effective use of Project Operations.
