I work part time as self-employed, and use Google Calendar to organise my time. I'd like to be able to include on my personal website a list of dates that I am available for hire.
Does anybody know of a way of extracting busy/free information from a Google Calendar and producing a report of which days I am completely free (i.e. days in which there are no events in my calendar)? This has to be a system that can be integrated on the web and dynamically updates; thus once implemented it should only require me to keep my Google Calendar up-to-date.
Bonus question: I only do this work at the weekends. Ideally, any solution would allow me to have it only report whether I'm free on a Saturday or Sunday.
