This project is a LED-style Digital Clock built using HTML, CSS, and JavaScript. It was developed as part of a project at Bangladesh Sweden Polytechnic Institute, Department of Computer Science. The primary objective of this project is not only to create a visually accurate and real-time digital clock but also to explore the concepts of time complexity and space complexity by analyzing the best algorithms behind time rendering.

- Real-time LED-style digital clock display.
- Simple, clean, and responsive UI.
- Accurate time rendering using JavaScript.
- Focus on time & space complexity analysis for efficient updates.
- HTML5 → Structure of the clock
- CSS3 → LED-style design and animations
- JavaScript (Vanilla JS) → Logic for fetching and updating time
We carefully considered time and space complexity while designing the logic:
- Time Complexity: O(1) → Time updates every second with constant-time operations.
- Space Complexity: O(1) → Minimal variables used, no extra memory overhead.
This ensures that the clock runs efficiently in real-time without performance issues.
