A vacation is a period taken off from regular work (Holiday) .
One feature of a "good" job is an inviting amount of vacation time, usually increasing over the years. Some employers also offer opportunities for lengthy sabbaticals. Some vacation time is usually assigned to regular celebrations, such as Christmas, the Fourth of July, and Thanksgiving. The rest can be taken when the worker wants it, with permission from their employer, or, in some cases, during a summer shutdown of operations when most employees take the same time off.
