I've used this calendar for many years. It helps me keep track of important dates and upcoming events. You will be able to see your entire semester on one page.
It's created in a Microsoft Word 2013 document. You can easily update it with your important dates. You can also print it and write on it.
I usually do two versions each semester: a teacher version and a student version. My teacher version includes things such as staff meetings, drills, my paydays, etc. The student version has units, daily tracking, and assignments due. You can also complete one for parents.
I've included a sample of my calendar as a guideline.
