Why is May 11 observed as the National Technology Day?
May 11 is marked as the National Technology Day to commemorate India's technological achievements, including the initiation of 'Operation Shakti' (Pokhran-II) at the Indian Army's Pokhran Test Range in Rajasthan in 1998. Following Operation Shakti, erstwhile Prime Minister Atal Bihari Vajpayee then declared India a full-fledged nuclear state, making it the sixth country to join the "nuclear club".
