'Zero Hour' in the Indian Parliament traditionally starts at 12:00 Noon. It is an informal session where members of Parliament (MPs) can raise important issues without prior notice. Zero Hour is not mentioned in the official rules of procedure and is a convention that has evolved over time. It follows the 'Question Hour', which typically runs from 11:00 AM to 12:00 PM.
The idea behind Zero Hour is to provide an opportunity for MPs to raise urgent matters that require immediate attention, especially those that do not fall under the purview of scheduled questions. While the 'Question Hour' is more structured and requires prior submission of questions, Zero Hour allows for a more spontaneous discussion. It has been a significant tool for parliamentary democracy, allowing MPs to highlight pressing issues like public grievances, policy failures, or current national concerns.
