What is a historical account and how do you write one about a part of your summer?

I have to write a two page historical account about my summer for school. But I have never written one before and I do not know how to write one or what points need to be in it in order to make it a historical account. I need to turn my paper in on the 30 of August so if you could help me it would be greatly appreciated.|||It's just like a diary of a what has happened, write it like a formal essay I suggest. Like how you'd talk about a historical event.
