Gary, a friend of mine was showing me how his calendars on Outlook at work included his personal calendars from his Windows Live subscription. I was very impressed and discovered with the beta version of Microsoft Outlook 2010 that I have the same thing. From work it looks like this:

On the left I have listed my work calendar, my home calendar, calendars from the various bands I’m in, and in Casa du Glassa, a calendar for the extended Glass family. I can turn on the calendars or leave them off as desired.

My home calendars look like this. It includes a calendar my father runs with all birthdays and anniversaries for family and relatives. Note the use of icons for some reoccurring events:

The nice thing is that now at work, on mobile or at home I can access all of my calendars in a moments notice. So double booking events such as a concert when I’m going to be out of town for a work conference should be a thing of the past.

For some people this might seem insane to run that many calendars and be involved in so many activities. For me, that’s just the way it has always been.
