UPDATE: Timetabler iCalendar will be decomissioned at the end of the Summer Term 2024. Celcat events dated from Monday 1 July 2024 will be pushed to staff and student Outlook calendars via AutoCalEx only.

Timetabler iCalendar enables staff and students to subscribe to the service to receive and view their personal timetable on their mobile device and several third party Calendars (e.g. Google).  When a staff member or student is added to Celcat Client, their College email address is added automatically; enabling the feed to be downloaded.

The link is unique to your timetable only and should not be shared with others.

This calendar appears as an overlay in Outlook, i.e. a separate calendar that can be made viewable or hidden by the user. 

  • Available to both Students and Staff with a College email address (with an email address in their email field on the Celcat record).
  • Changes to timetables are automatically updated by the calendar feed every few minutes.
  • It is personal to the staff or student, showing any events which are linked to the individual by their student or staff name or their association to a group or team.
  • The overlay does not affect the users’ other calendar.
  • The feed can be hidden at any time.
  • Can show the timetable for the whole academic year, or be subject to windows as per department choice. Learn more about Timetabling Publication Windows.
  • The events associated with a" Resource Non-availability" category will not be published on iCalendar.

Timetable Updates

"While every attempt will be made to minimize alterations to timetables, in some circumstances changes may be unavoidable. It is the individual responsibility to check the timetable regularly and refresh this for any updates, ensuring you have the correct information to attend your classes. If you print a copy you must check back for alterations as activities are likely to be updated, particularly during the first few weeks of term."
