FWIW, the average person works about 20 days a month. Teachers get at least 2 1/2 full months off in summer and 2 weeks at Christmas and a week during Easter break. According to my math, that is about 3 months.
No week off for Easter here. Spring Break, yes. Good Friday will be a bad weather make-up day this year. And, no ... 2 1/2 months during summer is not always correct. My wife is a teacher. Her last day of the school year this year will be June 5. She will have work to do over the summer to get ready for the next year ... some voluntary, some demanded. She reported for official duty in July last year, worked all through August well before the 1st day with students.
