They released the Nanakshahi calendar (Mool Nanakshahi Calendar) created by SGPC sponsored Sikh scholar Pal Singh Purewal. The calendar has been dedicated to the great Sikh warrior Baba Baghel Singh. Dal Khalsa spokesperson Kanwarpal Singh rued that the SGPC has killed the letter and spirit of Nanakshahi calendar by mixing it with Bikrami calendar, which had its roots in Hinduism. "We had mentioned dates of Gurpurabs [Sikh religious days] according to original calendar adopted in April 2003 as we believe that the amended version has an imprint of RSS ideology," Singh said.

Also it will be a rebuttal to those, who have been trying to erase this period from public memory. Activists mostly youngsters from Hoshiarpur, Ludhiana, Amritsar, Jalandhar, Nawanshahr and Moga participated in the sit-in to show their steadfastness towards the cause and also to pay homage to martyrs. On the concluding day (6 June) of its 72 hours sit-in protest, the organization vowed to
