Try your own, private installation of Calcium on our servers, with full System Administration rights. It's easy - no signup required and there's nothing to download or install. And, it's private - nobody else will be able to view or modify your calendars (unless you want them to.) Just pick a name for your trial and you'll have access to a fully enabled version of Calcium Professional, with up to 25 calendars and the Email Reminders and Custom Fields options.

The installation will work for two weeks, then will be disabled. If you decide to purchase the software and install it on your own server - or sign up for our Hosting Service - you can keep your data and settings from this trial.
