Answer: 1962
Notes: Zero Hour in Parliament starts at 12 noon during which members raise matters of importance, especially those that cannot be delayed. Zero Hour is the Indian innovation in the field of parliamentary procedures and has been in existence since 1962. However, it does not find mention in the rules of procedure. During zero hour, questions are asked about issues of public importance without prior permission. These questions are usually directed against individual ministers. Zero hour follows question hour.
