I have produced the annual school calendar templates for 2006-2007 (August to August)
They are A3 size and in MS Word (.doc) format so they are easily editable, they are best printed in colour but black & white also works.
There are several versions ... one plain template and others with public holidays included for Hong Kong, Thailand, England, USA
Hope these can save you some time when planning for next year.
All free and downloadable from .....
