It's not right to ask the question this way, here this will be better :) في وطنك متى تفتح وتغلق المدرسة /المدارس؟ ماهي اوقات بدء المدرسة وانتهائها في بلدك/وطنك؟ If you're looking for the translation (not sure since you didn't post your question) it means: When the schools starts and ends in your country? Hope this helps :)
