I heard on the news this morning that it is today. But I googled it and I can't back that up, someone on this forum http://forum.ebaumsworld.com/archive/index.php/t-49753.html said that it is actually on January 16th.
If your question is more so "What is it's purpose?" I guess my answer would be that you're supposed to eat something hot and spicy today.

You can probably find a hot spicy mix pickle in the asian/international food section in the grocery store. If you can't then make it yourself!

Spicy food derives its "heat" from the presence of reactive molecules in the food, such as capsacin. The amount of heat is proportional to the volume of these molecules as well as the various types of the molecules.
some are not hot at all, but the spicy one is much more delicious and famous
