The Chief Minister of India's northwestern State of Punjab, Parkash Singh Badal, announced that a public holiday will henceforth be observed, every year, on the Jain religious holiday of Mahavir Jayanti, and that this will be a "dry day" (ie. no alcohol sold or served) in the State of Punjab.
Analysis: The religious holiday occurs on the 13th day of the waxing Moon of the Hindu lunar calendar month of Chaitra. This year, the public holiday fell on March 31 (the day of the above-referenced announcement), and in 2008, it is expected to occur on April 18.
