Today is Day 2 of the annual festival for Nataraja celebrated in South Indian temples. May His dance bless. Here, I'll wait until tomorrow to go beseech His blessings. The temple will be far too crowded for my liking today.
Other than that, I don't really know. I'm sure your searching is as good as mine. Most 'serve everyone' types of temples probably wouldn't celebrate it, unless a particular priest or devotee sponsored something. Here, we have a sanctum called the Vasantha Mandapam that houses festival brass deities, and Nataraja will be placed in the center of that for 10 days, culminating in an early morning (5:30) parade and abhishekam.
