Detailed explanation of this Calendar:
This calendar originated because the modern calendar of Judaism, (the “current (authorized) Hebrew calendar” or what we often refer to as the “traditional Hebrew calendar”, “traditional rabbinic calendar”, or “modern Jewish calendar”), is so clearly wrong. Just how the current Hebrew calendar is wrong will be addressed shortly. However, we recognize that no individual or group has any responsibility or authority for the “authorized Hebrew calendar”, so we recognize this calendar has no authority, and as such, we do not, and have never expected, demanded, requested or required that anyone follow this calendar! So, you may wish to ask: “Without authority, why do you advocate this calendar?” It is a fair question we hope to answer herein.

Final thought – maybe God wants us to see (research) it watching in the sky.

Pensamiento final: tal vez Dios quiere que lo veamos (investiguemos) mirando en el cielo.
