It was the decision of Federal Cabinet to advance the clocks by one hour every year with the advent of summer to overcome the energy crisis and use maximum daylight. Pakistan experimented to advance one hour time in 2002 on the first Sunday in April at 00:00 to first Sunday in October at 00:00.
The country started to implement this practice again from June 1, 2008 to August 31, 2008 to meet the annual shortfall of electricity. The government later extended the schedule to October 31, which also included the holy month of Ramadan, which began in early September. This practice helped the government save around 250 MW of electricity per day, official sources in the Ministry of Water and Power said.
