You Say Calcutta, I Say Kolkata

While reading about Calcutta, I keep seeing the words Calcutta and Kolkata used seemingly interchangeably. For quite a while I've just been scratching my head, wondering why there were two spellings for it. I no longer have to wonder! I found an answer in my favorite online encyclopedia. Calcutta was the name given to it while it was controlled by the British. It looks like the official name is now Kolkata, although the rest of the world still seems to use Calcutta.
