Ask an Assamese how many Bihus he celebrates. The answer would be three—spring, winter and autumn. And of course a fourth, springing from popular artistes gigging at shows held across Assam for a full month and which are coeval with the advent of 24x7 television. Rongali or Bohag Bihu, the happiest and biggest in the troika, is by tradition a week-long affair. Even that timeframe is a stretch, but the dance-and-music continues on the loop on TV and social media until it’s time for the next Bihu. That’s ‘TV Bihu’—much like Pluto the planet, debated whether it’s the real deal or a con.
