Zap Calendar is quite possibly the most advanced calendar application available for Joomla today.  It is designed to meet demanding calendar needs which can not be met by any other product.  Read for yourself on what Zap Calendar can do and see if you agree:

Extensive iCalendar Support - Zap Calendar was written from the ground up to fully support the iCalendar standard  (iCalendar is the standard format for transferring calendar events between applications). Zap Calendar provides full import, export and synchronization of calendar events to and from external sources. Using a calendar program such as Outlook, Thunderbird or Google Calendar, downloading or uploading a single event or an entire calendar with 1,000's of events can be done easily with Zap Calendar.  iCalendar repeating events are also fully supported. Using the iCalendar subscribe plugin (available in Zap Calendar Pro), you can synchronize events created on remote calendars with Zap Calendar, allowing automatic updating of your calendar when an event changes in a remote calendar.

Plugin Support - Zap Calendar is the first Joomla calendar program that can be extended using Zap Calendar plugins. These plugins provide additional functionality to the calendar, including plugins for searching, weather, captcha, mapping, and social networking features like commenting and RSVP.

Third Party Application Support - Zap Calendar provides support for several popular Joomla extensions, including Community Builder, JomSocial, JomComment , sh404SEF and Z Weather. Zap Calendar also includes a Google Maps plugin, allowing you to show the location of all your events on a map.

AJAX Support - Zap Calendar's calendar view is AJAX enabled, allowing users to browse the calendar by day, week, month or year without ever refreshing the screen page. AJAX support is extended to Zap Calender modules, allowing independent browsing of calendars when multiple calendars are present on a page. AJAX support can also be found in the Comment, RSVP and Google Maps plugins.

Social Networking Support - Your website users can comment and RSVP to events using the provided plugins. In addition, Zap Calendar provides support for Community Builder and JomSocial by displaying a user's profile picture next to their comment or RSVP. When using JomSocial, event activities are posted to JomSocial's wall and JomSocial points are distributed, if enabled. Zap Calendar also allows sharing events on popular social networks like Facebook and Linkedin.

RSS Support - Zap Calendar supports publishing upcoming events in RSS format.

Events By E-Mail - Zap Calendar provides a special RSS mode that allows a weekly e-mail to be sent to subscribers automatically notifying them of the week's upcoming events.

Event Management - Multiple categories per event, repeating event support, linking events to articles, front-end event editing/creation, quick event creation mode, importing of events from CSV or iCalendar file formats.

Calendar Management - Multiple calendars per site, multiple calendars per page (via modules), personal calendars, spanning categories across multiple calendars, flat and tree-based category layouts, theme support, display/hide event categories on a calendar

Zap Calendar is released under the GPL license, which means you are freely able to view and modify the source code if you wish. You are also permitted to install it on more than one web site within an organization.  Subscribers receive software updates for 1 year.

Zap Calendar for Schools

Zap Calendar was originally developed for schools and provides features with schools in mind.  Zap Calendar supports multiple calendars, which allows you to provide separate calendars for categories such as school campuses, academics, sports, lunch menu, and PTO events.  Combining Zap Calendar's multiple calendars and date range feature, you can create  a school calendar for the current academic year and another for the next school year.  When browsing events using the monthly calendar, the year view can be customized to display the school year (July to June) instead of the calendar year (January to December).

If your sports teams are using an outside calendar service for listing their events, you can use the iCalendar subscribe plugin, available with Zap Calendar Pro, to import and synchronize the sporting events. This will allow you to display your team events using the same calendar interface as your other calendars.

The sequential events screen allows you to enter many events on a single screen.  For example, this feature can be used to enter a school menu where an entire month's menu can be entered in one screen.

Zap Calendar for Social Networks

Zap Calendar is the perfect application for social networking sites. Zap Calendar can provide a dynamic calendar experience with its Pro version.  Users can post comments on events and RSVP to them using the provided plugins.  Zap Calendar also supports JomSocial and Community Builder, allowing the display of profile pictures in comment postings and RSVP's. JomSocial's wall and point system is supported for posting comments and RSVP'ing to events.

You can share Zap Calendar events with your friends on Facebook, Linked in and other social networks by using the share icon.  You can alternatively send an e-mail link using the e-mail option.
