105 Free Calendar Templates. Microsoft has gathered all its Office calendar templates into one place. They’re free to download and use (‘for genuine Microsoft users’) and are available for the full range of MS products from Word to Publisher. You’ll need to be using Internet Explorer of course, this being Microsoft, and go through that naff anti-piracy validation. But if you’re in the market for a free calendar for your desk, pocket or wall, this is as good a place to start as any.
