The Cosmic Calendar is a concept introduced by astronomer Carl Sagan to help visualize the vast history of the universe by compressing its 13.8-billion-year timeline into a single calendar year. In this model, the Big Bang occurs at midnight on January 1, and all subsequent cosmic events are scaled accordingly throughout the year.

An interactive adaptation of this concept is available at https://quizpop.net/CosmicCalendar/, offering users a personalized exploration of cosmic history.

Key Features:

• Personalized Cosmic Event Finder: Users can input their birth date to discover which significant cosmic event aligns with their birthday on the Cosmic Calendar. For example, entering a specific date might reveal its correspondence with the formation of the Milky Way or the emergence of early life on Earth.
• Interactive Chronology Challenge: The platform presents a fun and educational challenge where users can sequence major cosmic events in their correct chronological order, enhancing their understanding of the universe's timeline.

This interactive tool not only personalizes the vast timeline of the universe but also educates users on the sequence of significant cosmic events, making the immense history of the cosmos more relatable and engaging.
