Sorting is probably the key to your problem here.

Presumably you have a big collection of all the courses you've scraped. First you'll need to be able to pull out all the courses given a particular location into a new list. You'll want this list to be sorted by the course date. Check out the various sorted collections (e.g. TreeSet). You'll probably also need to make use of a "comparator" to make sure your courses get sorted by their date.

Once you have that list, it's just a matter of iterating over it and finding the gaps.
