Calendar Plugin
The CalendarPlugin handles the macro
%CALENDAR% that inserts a
monthly calendar in the page. Multiple topics can be specified as the source
of the events, and these can be in any web. The calendar marks dates
corresponding to the events. Events can be listed literally in the topics,
or can be taken from the results of macro expansions (such as %SEARCH).
NOTE since release 2.000, the plugin now respects access controls on
topics containing events. You must have VIEW permission on these topics to
be able to see the events they contain.
Also since 2.000, preferences settings
in this topic are no longer read.
Please define preferences as non-plugin preference settings instead.

aslist |
Controls whether events displayed in calendar style (aslist=0) or list style (aslist=1). Note that specifying aslist=1 forces showdatenumbers=1 and defaults to show only one day's events (see day and days). This is done to ensure that the date number is formatted according to datenumberformat and that only the days that have an event are listed. |
0 |
day |
Specifies the first day to show. Only valid if aslist=1. |
1 |
days |
Specifies how many days of calendar data to list. Only valid if aslist=1. |
1 |
months |
Specifies how many months of calendars to display. Only valid if aslist=0. |
1 |
datenumberformat |
Specifies formatting for the date number in each cell. The formatting codes accepted are the same as those for the %GMTIME% variable. |
'$day' (if aslist=0)
' * $day $mon $year' (if aslist=1) |
todaydatenumberformat |
Specifies formatting for the date number for the current day (today) in the calendar. The formatting codes accepted are the same as those for the %GMTIME% variable. |
datenumberformat |
multidayformat |
Specifies formatting of the description for multi-day events. See Multi-Day Event Formatting for details. |

Event Syntax
Events are defined by bullets with the following syntax:
| Event type |
Syntax |
Example |
| Single: |
* dd MMM yyyy - description |
09 Dec 2002 - Expo |
| Interval: |
* dd MMM yyyy - dd MMM yyyy - description |
02 Feb 2002 - 04 Feb 2002 - Vacation |
| Yearly: |
* dd MMM - description |
05 Jun - Every 5th of June |
* w DDD MMM - description |
2 Tue Mar - Every 2nd Tuesday of March |
* L DDD MMM - description |
L Mon May - The last Monday of May |
* A dd MMM yyyy - description |
A 20 Jul 1969 - First moon landing
This style will mark anniversaries of an event that occurred on the given date. The description will have " (x)" appended to it, where "x" indicates how many years since the occurence of the first date. The first date is not annotated. |
| Monthly: |
* w DDD - description |
1 Fri - Every 1st Friday of the month |
* L DDD - description |
L Mon - The last Monday of each month |
* dd - description |
14 - The 14th of every month |
| Weekly: |
* E DDD - description |
E Wed - Every Wednesday |
* E DDD dd MMM yyyy - description |
E Wed 27 Jan 2005 - Every Wednesday Starting 27 Jan 2005 |
* E DDD dd MMM yyyy - dd MMM yyyy - description |
E Wed 1 Jan 2005 - 27 Jan 2005 - Every Wednesday from 1 Jan 2005 through 27 Jan 2005 (inclusive) |
| Periodic: |
* En dd MMM yyyy - description |
E3 02 Dec 2002 - Every three days starting 02 Dec 2002 |
* En dd MMM yyyy - dd MMM yyyy - description |
E3 12 Apr 2005 - 31 Dec 2005 - Every three days from 12 Apr 2005 through 31 Dec 2005 (inclusive) |
| Exception: |
Insert the following between the above syntax and the description:
X { dd MMM yyyy, dd MMM yyyy - dd MMM yyyy } |
1 Fri X { 01 Dec 2002, 06 Dec 2002 - 14 Dec 2002 } - Every first Friday except on the 01 Dec 2002 and between 06 Dec 2002 and 14 Dec 2002 |
For a table-style calendar, each day which has one or more events will have a
list of the descriptions of those events. Each event description will be set
in a small font. In other words,
format is:
$old<br /><small>$description</small>
For a list-style calendar, if an event falls in the selected time period, then
it is displayed (by default) as a bullet item with the date as dd Mmm yyyy In
other words,
datenumberformat is:
* $day $mon $year
and
format is:
$old - $description
This displays the events in a form very similar to that in which they are specified (although specific to a particular date).
The multidayformat option allows the description of each day of a
multiday event to be displayed differently. This could be used to
visually or textually annotate the description to indicate continuance
from or to other days.
The option consists of a comma separated list of formats for each
type of day in a multiday event:
first, middle, last, middle-unseen, last-unseen
Where:
- first is the format used when the first day of the event is displayed
- middle is the format used when the day being displayed is not the first or last day
- last is the format used when the last day of the event is displayed
- middle-unseen is the format used when the day being displayed is not the first or last day of the event, but the preceding days of the event have not been displayed. For example, if an event runs from 29 Apr to 2 May and a May calendar is being displayed, then this format would be used for 1 May.
- last-unseen is the format used when the day being displayed is the last day of the event, but the preceding days of the event have not been displayed. For example, if an event runs from 29 Apr to 1 May and a May calendar is being displayed, then this format would be used for 1 May. Note that in the previous example (event from 29 Apr to 2 May), this format would not be used for a May calendar because the event was "seen" on 1 May; so, the last format would be used for 2 May.
Within each format, date information for the current day can be
substituted using the same format codes as accepted by
%GMTIME%. An extension to these codes allows the date of the
first and/or last day of the event to also be rendered.
-
$first(format) will render the first date of the event according to format, where format is, again, a string of codes acceptable to %GMTIME%.
-
$last(format) will render the last date of the event in the way just described for $first()
Missing formats will be filled in as follows:
- middle will be set to first
- last will be set to middle
- middle-unseen will be set to middle
- last-unseen will be set to last
Missing formats are different from empty formats. For example,
multidayformat="$description (until $last($day $month)),,"
specifies an empty format for
middle and
last. The result of this
is that only the first day will be shown. Note that since an
unspecified
middle-unseen is set from the (empty)
middle format,
an event that begins prior to the calendar being displayed but ending
in the current calendar will not be displayed. In contrast,
multidayformat="$description" will simply display the description for
each day of the event; all days (within the scope of the calendar)
will be displayed.
The default format is to simply display the description of the event.
Other sources of calendars
You can also use the
Foswiki:Extensions.CalDAVPlugin to recover calendars from
a CalDAV server.

Settings
Any of the recognized
CALENDAR{} macro attributes can be defaulted using preferences. These
preferences all start with
CALENDARPLUGIN_ and end with the upper case name
of the attribute. For example, the following affect only Calendars on this topic:
-
- Set CALENDARPLUGIN_FORMAT = $old
$description
- Set CALENDARPLUGIN_CELLALIGNMENT = center
- Set CALENDARPLUGIN_GMTOFFSET = +10
- Set CALENDARPLUGIN_WEEKSTARTSONMONDAY = 0
Preferences can be set at the site, web, topic or user level. See
PreferenceSettings for more information.
Note: this is different from TWiki
CalendarPlugin for significant performance reasons, and because in foswiki, its prefferable not to modify topics in the System web.
Installation Instructions
You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.
Open configure, and open the "Extensions" section. "Extensions Operation and Maintenance" Tab → "Install, Update or Remove extensions" Tab. Click the "Search for Extensions" button.
Enter part of the extension name or description and press search. Select the desired extension(s) and click install. If an extension is already installed, it will
not show up in the
search results.
You can also install from the shell by running the extension installer as the web server user: (Be sure to run as the webserver user, not as root!)
cd /path/to/foswiki
perl tools/extension_installer <NameOfExtension> install
If you have any problems, or if the extension isn't available in
configure, then you can still install manually from the command-line. See
https://foswiki.org/Support/ManuallyInstallingExtensions for more help.
You should see two calendars near the Event list above and a current month calendar below (using css style section inline):
