Project Overview
The idea for the Happy New Year project was born at the end of November 2025, with the goal of creating a modern and elegant web app to celebrate the arrival of the New Year, aimed at the Spanish audience.
The app features a main countdown synchronized to the CET timezone, as well as individual countdowns for 12 different countries around the world, each with their own UTC offset.
A professional dark/light mode toggle was implemented with localStorage persistence and FOUC prevention, ensuring a seamless user experience across page navigations thanks to Astro View Transitions.
The project integrates a complete email subscription system: users can subscribe to receive a New Year greeting email, managed through Supabase Edge Functions and the Resend API, with full GDPR compliance.
