April Fool Periodicity

One day before April 1st. I thought it would be  interesting to look at the search volume for April Fools day on Google Trends. What better example can you find than this for periodicity in search volume. (Click image to enlarge)

It is nice to see that there is a spike every April fool’s day but it also interesting to note the countries that celebrate Aril Fools day. In America it is most searched for but New Zealand are not far behind. They must take it very seriously given their small population. In the UK, we are somewhat more reserved being the last in the list.

What is it with the people in Oakland, New Jersey. How come they search for April Fools so often? Given the assured spike in search volume, mental note to self: prepare something for next year.
