Youm-e-Takbir
Youm-e-Takbir (; lit. The day of greatness) is celebrated as a national day in Pakistan on May 28 in commemoration of Chagai-I and Chagai-II series of nuclear tests. The nuclear tests made Pakistan the seventh nation to possess nuclear weapons and the first in the Muslim world. Etymology

This phrase is recited by Muslims in many different situations. For example, when they are very happy, during times of extreme stress, to express approval, to praise a speaker, or as a battle cry (contemporarily used by Pakistan Army). In the Islamic world, instead of applause, often someone will shout Takbir or Nara-e-Takbir (in Urdu or Persian) and the crowd will respond with Allahu Akbar (God is great). The word is also used in Muslim prayers. The Government of Pakistan asked for proposals from the nation to decide a name by which the day should be celebrated. A country wide campaign was launched to select the name for this particular day. Thousands of names were propose by millions of Pakistanis. This name was suggested by more than one person. All the people who suggested this name were given away Prime Minister Award. Youm-e-Takbir here can be translated to "The day of greatness" or "The day of God's greatness". History
