Special worship of Lord Shiva is done in Shravan month. According to the scriptures, Shravan month is most dear to Lord Bholenath. Shravan month is considered to be the holiest month of the year.
This time the month of Shravan starts on July 6 and will end on August 3. A wonderful coincidence is being formed on the month of Shravan, because the first day of the start of Sawan is Monday, while the last day of Sawan i.e. August 3 is also the day of Monday.
According to Shiva Purana, whoever observes Monday fast in this month, Lord Shiva fulfills all his wishes.
