I used Trumba for a year and really liked it. But when they wanted me to renew for $100, I decided to look at all of the free web calendars out there first.

I’ve switched to Google Calendar and it is working well for me. We need a family calendar that we can access from anywhere and that emails us updates and reminders. Walt Mossberg reviewed Google Calendar in this WSJ article.

Yahoo has one and some of the To Do List websites do too... See Walt Mossberg’s Wall Street Journal Personal Technology article on web to do lists at: Net-Based To-Do Lists Permit Collaboration By Family, Colleagues
Other web calendars include:
