You can select multiple different ways of viewing this calendar.
Below you can see the days in a drop down menu format.
If you click on 'see more events' under this display you get to see the calendar as a colour coded display more like a traditional calendar.
Items coded in red (with the category 'correction') are items were the details (eg timings) that have changed since the published printed calendar.
On that display, you also have the ability to filter events (show categories button) so that you only see events of a given category.
