Chronodate

Chronodate is a cosmological date system that denotes the chrons that have passed since the theorized start of spacetime.  Unlike traditional human calendars deeply influenced by astronomical cycles of the Earth and the Moon, Chronodate offers a linear way to conceptualize extremely long and short timescales relevant to cosmological events.

Advantages of Chronodate

• Linear: Avoids the cyclical nature of astronomical calendars.
• Universal Reference: Offers a potential shared frame of reference for cosmic-scale historical inquiries independent of a specific planet or star system.
• Precision for Extreme Timescales: Accurately tracks cosmic events that occurred even fractions of a chron after the Big Bang or during the extremely distant future.

History of Chronodate

As descendants of solarian humans dispersed throughout the Milky Way galaxy, Earth-centric time units derived from the Sol system gradually lost their widespread significance. The second, already precisely defined using the caesium standard, became the established unit for time measurement. This transition aligned with a larger shift away from the Earth-based sexagesimal (base 60) system. Alternative terms such as "arcs," "turns," "spins," "cycles," and "revos" emerged. While the term "second" generally persisted, the use of "chron" as a synonym became commonplace.

Comparisons to Other Proposed Cosmic Calendars

While Chronodate prioritizes linearity and scientific precision, other cosmological timekeeping systems have been proposed, emphasizing different aspects of cosmic history:

• Epoch Cycle Calendar: This calendar divides the history of the universe into distinct epochs based on major cosmological events (e.g., Big Bang, formation of galaxies, emergence of life). Each epoch represents a "chapter" in cosmic history, offering an intuitive way to grasp the universe's evolution.
• Cosmic Expansion Calendar: This proposed system directly translates the universe's expansion rate into time units. Events are dated by how much the universe has expanded since the Big Bang. This highlights the impermanent nature of cosmic distances and the dynamic nature of spacetime.
• Star Formation Calendar: Focused on astrobiology, this calendar counts time based on the average interval between the formation of Sun-like stars in the galaxy. This method provides a context for the likelihood of intelligent life arising elsewhere in the universe throughout different periods.

Chronodate excels in precision and universal adaptability but might lack intuitive interpretation compared to epoch-based systems focused on landmark events.
