Web-based calendar programs

[Sarah Nesbeitt, Maxwell Library]

I'm interested in discovering more information about programs or packages
which can produce calendars to be used in web pages.

Currently, I edit the HTML file containing a calendar for our library
hours (http://www.bridgew.edu/depts/maxwell/octhours.htm) manually.
I'd be interested to hear about any product which could automate this
process a bit.  In other words, to save the trouble of checking which
dates fall on which days from month to month and amending the calendar
(which I currently have set up in table format) to reflect this.
The manual process isn't difficult at all, but it would be nice to have
a product in which no knowledge of HTML was necessary to update the 
calendar... in other words, so someone else could easily be taught to do
it.

Does such a thing exist?

Thanks,

Sarah
