This year (as often is the case) I forgot the Pakistani Independance Day, August 14th. It celebrated 59 years and is now the 6th most populous country in the world.
I read a bit about the etymology or word origin of Pakistan and found the following:
The name "Pakistan" (IPA: /paːkɪst̪aːn/) means "Land of the Pure" in Urdu and Persian. It was coined in 1933 by Choudhary Rahmat Ali, who published it in the pamphlet Now or Never as an acronym of the names of the "Muslim homelands" of western India — P for Punjab, A for Afghania (the Afghan areas in the Northwest Frontier Province), K for Kashmir, S for Sindh and tan for Balochistan. An "i" was later added to the English rendition of the name to ease pronunciation.
