The festival of Uttarayan is a uniquely Gujarati phenomenon, when the skies over most cities of the state fill with kites from before dawn until well after dark. The festival marks the days in the Hindu calendar when winter begins turning to summer, known as Makar Sankranti or Uttarayan. On what is usually a bright warm sunny day with brisk breezes to lift the kites aloft, across the state almost all normal activity is shut down and everyone takes to the rooftops and roadways to fly kites and compete with their neighbors.

Kites of all shapes and sizes are flown, and the main competition is to battle nearby kite-flyers to cut their strings and bring down their kites. For this, people find their favored kite-makers who prepare strong resilient kite bodies with springy bamboo frames and kite-paper stretched to exactly the right tension. Lastly, the kites are attached to a spool (or firkin) of manja, special kite-string coated with a mixture of glue and glass to be as sharp as possible for cutting strings of rival kites. Production of kites and kite supplies can be seen on the streets of Ahmedabad beginning in November, to get ready for Uttarayan, and nowhere more so than in Patang Bazaar, the special kite market that appears in the old city. For the week preceding the festival, it is open 24 hours a day for all kite lovers to stock up for the festivities.

Parents who normally find their children hard to get out of bed for school will find them setting the alarm for 5 am on 14th Jan., to get up and start flying kites in the ideal pre-dawn wind. The atmosphere is wonderfully festive, as whole families gather on the rooftop, special foods like laddoos , undhyu or surati jamun are prepared for eating over the course of the day, and friends and neighbors visit each other for group kite-flying fun. Often people look out for which of their friends has the optimum terrace for kite flying and many will congregate there. This leads to many social gatherings that would not otherwise occur, as one person's brother's friends meet their classmate's cousins, because they have all gathered on the rooftop of the same mutual friend. People often find themselves marking time by Uttarayans: "I met you three Uttarayans ago, right?" is a not uncommon phrase. At night, kite fighters send up bright white kites to be seen in the darkness, and skilled flyers will send aloft their tukkals with strings of brightly lit lanterns in a long line leading back down to the rooftop. From early morning to late at night, Uttarayan provides lots of fun and beautiful sights to remember for a long time.

Since 1989, the city of Ahmedabad has hosted the International Kite Festival as part of the official celebration of Uttarayan, bringing master kite makers and flyers from all over the world to demonstrate their unique creations and wow the crowds with highly unusual kites. In past years, master kite makers from Malaysia have brought their wau-balang kites, llayang-llayanghave come from Indonesia, kite innovators from the USA have arrived with giant banner kites, and Japanese rokkaku fighting kites have shared the skies with Italian sculptural kites, Chinese flying dragons, and the latest high-tech modern wonders. A master kite maker and famous kite flyer Rasulbhai Rahimbhai of Ahmedabad trains of up to 500 kites on a single string have come to be a classic attraction. Almost every known variety of kite can be seen in the skies over Sardar Patel Stadium in Ahmedabad, from box kites to high-speed sport kites, from windsocs and spinsocs to hand-painted artistic kites.
