$AllowUserChoice: If this variable is set to 1, visitors won’t be able
alter the calendar style, but *will* still have the option to select
specific months (unless, of course, $PreviousLastOnly is also set).

$AllowHTML: If this variable is set to 1, HTML code is allowed in
calendar entries. If it is set to 0, HTML code is stripped.

$AllowMultiDate: If this variable is set to 1, it will be possible to
enter events not only for specific dates, but also for date ranges.

$bgcolor_normal: The color (defined with standard HTML RGB hex code) to
be used as the background for “normal” dates (dates with no events) on
the graphic calendar.

$bgcolor_header: The color to be used as the background for the header
(month line) at the top of the calendar.

$bgcolor_special: The color to be used as the background for dates on
which an event occurs.

$textcolor_normal: The text color to be used for for “normal” dates on
the calendar.

$textcolor_header: The text color to be used for the header.

$textcolor_today: The text color to be used for today’s date on the
calendar.

$textcolor_special: The text color to be used for event listings.

$TableFont: The “FACE” specification (if any) that you want used in
your calendar tables. If you’ve defined a font style for the page
as a whole, and want it used in the calendar tables, as well, define
it here, as otherwise, Netscape Navigator will use a visitor’s default
font within the tables, no matter what’s used on the rest of the page.
You can also use this, of course, to deliberately define a font for
the tables different from the one you’ve used on the rest of the page.

$HourOffset: If you are in one time zone and your Web host is in
another, you can use this variable to make sure that your calendar
always shows the correct date for your location. For example, if your
server is located in the Eastern time zone, but you’re in the Pacific
time zone, set it to “-3″.

$MonSunWeek: If set to 1, calendar weeks will run from Monday to Sunday
rather than from Sunday to Monday. (This can be handy if you list a
lot of Saturday/Sunday events and want the weekend days to be more
clearly “linked” visually.)
