Browsing the Internet is a great way to learn about both the science and the traditions associated with Leap Year. Using a search engine, like Google, when you enter the words "Leap Year" you get approximately 2,180,000 results, far more than most people would have the time to research. A quick review of the ten on the first page and a cursory look at the ten on the second page gives a taste of what can be found on the subject.
To help you focus your research, Google has included additional search terms at the bottom of the results page under the heading "Searches related to: Leap Year". Use these hints to modify your own search terms, based on your specific interests. For example, adding "trivia" to your search, reveals a set of appproximately 110,000 results or adding "traditions" reveals another 138,000 results.
The Yahoo search engine also provides related searches under the heading "Also try:..."
