Summer vacation
In the school year 2016–2017 the summer break for Saudi Arabian students started from 24th of May till the 17th of September. This means it will be 110 days, 3 Months and a half. In 2018-2019, schools will end in May 13th and start early September, this is because the Ministry of Education wants students to finish school before Ramadan begins.
