The time taken to frame the Constitution of India was approximately 2 years, 11 months, and 18 days. The Constituent Assembly first met on December 9, 1946, and the Constitution was adopted on November 26, 1949. The Assembly debated over 167 days in total, producing India's Constitution with 395 Articles and 12 Schedules. This comprehensive process was led by the Drafting Committee chaired by Dr. B.R. Ambedkar and involved contributions from 274 members.

For comparison, the drafting of the United States Constitution took a much shorter time during the Constitutional Convention in Philadelphia, beginning in May 1787 and concluding on September 17, 1787, lasting about four months. This draft was instantly followed by a ratification process among the states.

Thus, the framing of the Indian Constitution was a longer and more detailed process compared to the initial framing of the U.S. Constitution.
