Date Conversion

Conversion tools between 28x dates and other calendar systems will be available here in a future release.

The conversion algorithms are defined by the 28x Time Standard v0.1: the fixed epoch (Gregorian 2026-03-20 UTC = 28X-0000-01-01), the regular cycle structure (13 × 28 days + 1 intercalary day), and the 28x leap-year rule.

The 28x Time API is live at api.28x.org — convert dates, query the current 28x coordinate, and generate AFN minting metadata programmatically.
