The fifth month of the Hindu calendar is known as Shravan. It commences from the end of July to the end of August in the Gregorian calendar. It is one of the holiest months in the Hindu calendar where most of the sacred vrats, festivals and rituals are celebrated. This month is mainly devoted to Lord Shiva and many devotees undertake a fast during this period to seek the blessings of Lord Shankar. Shravan maas for the North Indians in 2016 falls on July 20th to August 18th. For the South Indians, it falls on the August 3rd to September 1st. The reason behind this 15-day difference is because the South Indians follow Amavasyant Calendar and the North Indians abide by the Purnimant Calendar.
