The English school year runs from early September to mid- or late July.
Individual schools may be closed due to teacher training, bad weather, or other unplanned events.
Holidays create a marked reduction in peak traffic congestion periods on many routes.
The English tourism industry monitors websites that provide up-to-date school holiday information, and adjusts prices accordingly.
Parents who decide to save money by taking a holiday during term risk damaging their children's education and fines or warnings from their school.
