Erflett’s standard calendar conversion utility, «Erflett-SC», has been released
On 19 May 2025, the Fulika Calendar which is the standard civil calendar of Erflett was finalised, and on 18 October of the same year, the standard seasonal calendar the Theotos Calendar was finalised; then, an official utility for converting between these two standard Erflett calendars and Earth’s Gregorian calendar, the «Erflett Standard Calendar Converter» (Erflett-SC), has now been launched.
The utility: https://systems.belkosmos.com/calendar/standard
What is Erflett-SC?
The conversion utility provided on this occasion, Erflett Standard Calendar Converter (Erflett-SC), is based on the « Erflett Three-Calendar Conversion Tool», which was released independently by Saika Shiodome on 25 October 2025. Staff at this institute have refined this tool, integrating several features from Ms. Shiodome’s previously published «Fulika Calendar–Gregorian Calendar Conversion Tool», resulting in the Erflett Standard Calendar Converter — commonly known as Erflett-SC — which this institute is now releasing as an official product.
This utility offers the following features.
- Conversion between the Fulika, Theotos and Gregorian calendars
- Calendar display for the Fulika and Theotos calendars
- Fulika Calendar Annual Trait Checker
This update has rectified a bug in Ms. Shiodome’s tool concerning the «handling of the first year of the Common Era». This issue caused the non-existent year «0» to appear in the Common Era calendar, resulting in a one-year discrepancy when converting to the pre-Common Era era.
