I'm a Kubuntu user moving to Unity, one nice feature that the KDE panel calendar (the one that pops up when you click on the clock) had is that it indicated my local public holidays. I think each holiday had a red square around it and when you clicked on it it showed the name of the holiday.
Can this be set up with for the Unity panel calendar?

The only part that is handled by the indicators is the menus themselves. The window title and the window controls are all handled by Unity itself. So to do that specific effect you'd need to write an applet that did it.
But, there was something similar done on UNE back when it used GNOME Panel. You might be able to use the applet there and get some of the same effect. Or at least start you on your path.
You can do it by :
=> Open KOrganizer and navigate to Calendars (Configure KOrganizer- General- Calendars)
=> Click on ADD Select DAV Groupware Resource
=> Akonadi_davgroupware_resource will popup, click Cancel.
=> Now you will be able to add Akonadi Resource manually.
=> Under Add server configuration, choose CalDAV. Remote URL format is "https://www.google.com/calendar/dav/Calender_ID/events/ . Personal calendar_id is usually your Gmail Address .
you're done.

The only possible solution I can think of is the following: Evolution, as I am aware, features synchronization with Google Calendar (I use Thunderbird myself so I cannot guarantee how well it works). Google Calendar has plenty of options, including subscribing to public calendars, amongst those I am sure there is one for your region's holidays. The solution would be subscribing to that specific calendar in GC, then synching the calendar with Evolution. All of Evolution's marked dates should automatically be added to the panel calendar entry.
Here are a few links I hope you find helpful:
