Many sites offer a single month at a time. That works okay since people only print one month at a time. Downloads are usually in Word, Adobe, or Excel. Which you use depends on which software you are comfortable with. If you know Excel best then get an Excel calendar. If you are very good with Word, there are formats available which can be adjusted on the screen. It takes some practice to add notes to any template, but it's not too bad with practice.
