Why Switch to 360 Days?

The 360 days calendar redefines timekeeping by aligning perfectly with the tropical year. With 360 days divided into 12 months of 30 days each, and a slightly longer second (1014.5616 milliseconds instead of 1000), this system eliminates the need for leap years or periodic corrections, offering unmatched simplicity and precision.

  • Simplified Structure

    12 months of 30 days each total 360 days per year, providing a balanced and uniform calendar system.
