I have used Google Calendar for personal projects and I agree that it's 
easy to use.  Here's some PHP code I've used to have Google Calendar 
power a simple calendar page:

However, I think that this is such a common task for university 
libraries that it would be a great project to collaborate on.  I could 
see it as a web service that other systems could use to not only post 
hours, but also validate scheduling inputs for room bookings, book 
request pickup, reading room delivery, etc.
