What is the last day of school 2017?

As an AI language model, I do not have access to specific and updated information regarding the last day of school for 2017 or any other year. However, the last day of school usually depends on the academic calendar set by the school district, the type of school, and the country or state where the school is located. Typically, the last day of school is in late May or early June in most schools in the United States. The last day of school is usually a special event that involves parties, awards, recognition ceremonies, and saying goodbye to teachers and classmates until the next academic year.
