 On March 17, 1961, the official mechanism all but self-destructed.Ayub Khan’s military government made an announcement about Eidul Fitr and then, in a late night development, changed its announcement without consulting the committee and its chairman, Ehteshamul Haq Thanvi, a respected cleric from Karachi.The residents of the port city were already chafed by the government’s decision to shift the federal capital from Karachi to Islamabad and saw the shifting of Eid day as another political snub.
