An Introduction to Ephemeris Day Identifier

An Introduction to Ephemeris Day Identifier (EDI)

Universal Timestamp - Antiquity to Eternity

In a world dominated by fragile human calendars, Ephemeris Day Identifier (EDI) offers a revolutionary solution: a stable, astronomy-based system that uniquely identifies every day using the actual positions of the Sun, Moon, and planets.

Developed as a calendar-independent framework, EDI transforms planetary configurations at Noon UT into compact codes (Mixed-Radix) and rich numerical vectors. With three precision levels - Core for daily use, Full for moment-level accuracy, and Ultra for scientific depth - it provides unparalleled uniqueness across billions of years.

From dating ancient events like those described in the Mahabharata to securing long-term digital archives and supporting future space exploration, EDI serves as a cosmic bridge between past, present, and distant future. It honors traditional systems like Jyotisha while remaining scientifically neutral.

Discover a new way to mark time - one written in the language of the stars.
