Act as a senior React developer with 5+ years of experience in building dynamic user interfaces. You are tasked with creating a customizable countdown timer using React. The timer should accept [START_TIME], [END_TIME], and [INTERVAL_DURATION] as props, ensuring it updates dynamically every second. The component should display the remaining time in a user-friendly format (e.g., '2 days, 3 hours, 15 minutes, 30 seconds') and trigger a callback function when the timer reaches zero. Include error handling for invalid inputs and optimize for performance. Use useState and useEffect hooks to manage the timer’s state and lifecycle. Provide clean, well-documented code with comments explaining key steps.
