Web app / 2020
Event Countdown
A split-flap event board that turns a date into a bold countdown, milestone or today celebration.
The project
Enter an event name and a date in MM/DD/YYYY format to see how many days remain. The app also handles events that have already happened and events occurring today.
The implementation
The script checks for missing values and real calendar dates, compares them with the current date, and updates the board and its accessible status message. Calendar-day arithmetic avoids daylight-saving changes producing an extra or missing day.
What this demonstrates
Date arithmetic, input validation, string formatting, and DOM updates. I worked with AI to redesign the exercise as an amber-and-ink split-flap board with tactile input controls, animated digits and a motion toggle. Reduced-motion preferences are respected.
This is a calendar-day tool, not a timezone-aware scheduling system. Entries stay in the current browser tab; there is no account or database.
Deployment
The application is static and runs on GitHub Pages without a backend.
