There's no 'set' days that all providers take off. Some do not take any holidays at all, others take the whole summer off. Some providers ask for 2 weeks paid holidays, and others do not ask for payment. Depends on what providers are asking in YOUR area.

In my manual, I state that I take up to 10 weeks off without pay per year. This allows me to take my well-deserved break, and spend time with family and friends. I let parents know 3-4 weeks ahead of time, or when I find out.
