Himachal Pradesh Statehood Day, also known as Himachal Pradesh Foundation Day, is observed in the Indian state of Himachal Pradesh every January 25. This day commemorates the establishment of Himachal Pradesh as a state within the Indian Union on January 25, 1971, when it gained its own government led by Chief Minister Yashwant Singh Parmar. The state was formed from the integration of 28 princely states and has a rich history, with references to its ancient kingdoms found in the Mahabharata. The day is marked as an official holiday in Himachal Pradesh, allowing residents to celebrate their state's heritage and autonomy. It is distinct from Himachal Day, which is celebrated on April 15 to recognize the incorporation of the hill states into India.
