"Finding Linux-based calendar clients, like Evolution or Mozilla
Lightning, is easy — but what about the server-side software?
You'll find some great calendar servers for Linux, if you know
where to look. From light-weight to heavy duty, Cosmo to Darwin,
we've picked five of the best open source calendar servers for
Linux for you to try.
"Calendaring software has come a long way on the client side in
recent years; the Linux desktop has a healthy selection of apps to
choose from, including Evolution, Mozilla Lightning, and
KOrganizer. But, at the same time, much of their usefulness really
stems from the popularity of the server-side calendar sharing
protocols, iCalendar and CalDAV. Niche sites like Remember The Milk
and big online service providers like Yahoo and Google have made
shared calendars common place. Anyone can publish a calendar feed,
confident that everyone on the Web can subscribe to it on the OS
and device of their choosing and stay up-to-date.
"But just like you don't want a @gmail.com email address on your
business card, serving up your business's public calendar of events
through Google Calendar or Windows Live Hotmail Calendar can make
your organization look less-than-professional."
