A deadline is a specific date or time by which a task or project must be completed. It serves as a time limit that helps individuals and teams prioritize their work and manage their schedules effectively. Deadlines are commonly used in various settings, including schools, workplaces, and personal projects. Meeting a deadline is important because it ensures that work is finished on time, which can affect overall productivity and success. Failing to meet a deadline can lead to consequences such as missed opportunities, penalties, or a loss of trust among colleagues or clients.
