Welcome to CalConnect

Welcome to CalConnectSM, The Calendaring and Scheduling Consortium.

You don't need to be a member of CalConnect to implement a standard. You need to be a member of CalConnect to influence a standard.
We are a non-profit partnership between vendors of calendaring and scheduling systems and tools, and users of those tools. Our purpose is to improve all aspects of calendaring and scheduling, in particular interoperability. We do this by improving existing standards, developing new standards, offering interoperability testing for calendaring and scheduling systems and tools, collaborating with other organizations with similar goals, and conducting periodic conferences where engineers and customers meet and interact in a collegial atmosphere. Although CalConnect is not a standards development organization, virtually every important calendaring or calendaring-related standard over the last five years has been authored, edited and/or coedited by members of a CalConnect Technical Committee.

We invite you to learn more about CalConnect, and we hope you will become a participating member. If you have any questions, please use the contact form, or e-mail us directly at contact@calconnect.org.


Coming Events


What we are working on now – major projects underway in CalConnect Technical Committees – become a member and help make these things happen
  • Abstract Calendaring API - We need a full "CRUD" (Create/Read/Update/Delete) Abstract Application Programming Interface and Calendaring Architecture for Calendaring and Scheduling
  • Autodiscovery - One-stop setup for devices and new service providers for calendaring, e-mail, etc. based on internet standard protocols
  • CalDAV Alarms - Extend alarm support to allow for cross-device dismissal, proximity triggers based on location, default alarms in CalDAV
  • CalDAV Attachments - Extends the calendaring server to manage attachments
  • CalDAV/CardDAV Sharing - Sharing calendars and contacts between users across systems
  • CalWS-REST and CalWS-SOAP - We need to (finally) provide platform and system-independent calendaring and scheduling operations APIs for web services - it's long past time
  • Consensus Scheduling (VPOLL) - TimeTrade, Doodle, WhenisGood do it, it should be interoperable - scheduling driven by the attendees who get to vote on the best times and locations for group events
  • Event Publishing Extensions - Calendaring standards need to support the rich environment of Web 2.0 (and beyond) for the publication of public events - rich text, participants and image support
  • iSCHEDULE - We need server to server scheduling between dissimilar systems - we have had client to server scheduling for a long time
  • jCal - More web 2.0 - We need a standard representation of iCalendar in JSON. It's a natural follow-on to the recently completed xCal (iCalendar in XML)
  • Non-Gregorian Calendars - Establish a way for recurrences to work with non-Gregorian calendar systems, in particular lunar/solar calendars
  • OASIS WS-Calendar - Working with OASIS to develop their new WS-Calendar standard (scheduling for the Smart Grid), based on xCal, CalWS-REST and CalWS-SOAP
  • PUSH for CalCAV (and CardDAV) - Extend CalDAV and CardDAV with standardized support for PUSH notifications
  • Tasks (VTODOs) - Extend the functionality of VTODOs to support needs such as project management, smart power grids and business task scheduling.
  • Timezone service and registry - Full timezone support via dynamic server calls rather than embedding timezone information in events - no more having event times wrong when timezones change and your software isn't updated
  • VAVAILABILITY - New iCalendar component to describe availability, to 'condition' freebusy lookup and scheduling (e.g. you may be 'free' at 3 a.m. but you aren't available for a meeting)
  • vCard Resources - Define the vCard representation of calendaring resources to ease the discovery and scheduling of resources between any calendar client and server.
