Why Lahore Congress formalised the demand of ‘Purna Swaraj’ and when it accepted?

In December 1929, under the presidency of Jawaharlal Nehru, the Lahore Congress formalised the demand of ‘Purna Swaraj’ or full independence for India. It was declared that 26 January1930, would be celebrated as the Independence Day when people were to take a pledge to struggle for complete independence. But the celebrations attracted very little attention. So Mahatma Gandhi had to find a way to relate this abstract idea of freedom to more concrete issues of everyday life.
