What's the easiest way to build an appointment booking website?

Question

My wife is starting a new business and wants me to create a website for her that will allow clients to book appointments. I could obviously go ahead and start building something from scratch, but given that this is a fairly standard problem, I would prefer to reuse an existing solution (preferably in Java, but there is some flexibility on this) or build on top of a hosted solution like Google Calendar. What would you recommend?

Answer 1

There are extensive tools for the Google Calendar API. Specifically read the Google Calendar Developer's Guide.

Answer 2

Do NOT build your own from scratch; it's a surprisingly hard process (if you're curious, look into the iCalendar standard; there's a surprisingly large amount of complexity involved). As someone who has tried to develop this sort of thing from scratch before, I'd highly recommend using an existing hosted solution such as Google Calendar.
