It would be helpful when posting details of multi-day events if they can be entered to the calendar properly by the originators please. This would save me a lot of house keeping time.
To link multiple events to one posting, simply click the "Link to Calendar" button again and add the next event details.
If an event spans several days, then you can cover this by entering the first date and the number of days it runs for. There is a maximum of 25 days but if it runs for longer you can add a second event that runs for up to another 25 days.
