Technical details

1. Parsing URL Data

When the countdown page loads, the script checks the URL for encoded data (date and message) from URL parameter. This data is decoded and used to set the countdown target and display message. If no data is found, a default countdown to New Year’s Day 2025 is shown.

2. Time Calculation

The time remaining until the specified event is calculated by comparing the current time with the target date. The difference is broken down into days, hours, minutes, and seconds.

3. Real-Time Rendering

The calculated time is rendered on the screen, updating every second. The timer displays the remaining days, hours, minutes, and seconds. The minutes and seconds digits transition smoothly, creating an animated effect.

4. Completion Handling

Once the countdown reaches zero, the timer stops, and the page displays a completion message. This marks the end of the countdown.

5. Customization and Sharing

Users can create a new countdown by entering a message and selecting a date/time in a form. Once submitted, a URL with the encoded data is generated, allowing the countdown to be shared with others.

6. Full-Screen Mode

The timer includes a button to toggle full-screen mode, enhancing the user experience by allowing the countdown to be displayed prominently on any device.

Conclusion

This countdown timer is a simple yet effective tool for creating visually appealing and shareable countdowns to any event. The smooth animations and real-time updates provide an engaging experience for users.
