Dates based on a global trumpet call when observation confirmed; otherwise, dates calculated on lunar illumination (Points east from first sighting - including Israel - may be delayed an additional day on the traditional Gregorian calendar)
Global ObservationThis calendar is based on global observation of the lunar cycle. A Biblical Month is considered to begin at sundown (where you are currently located) following the first sighting (confirmed by a second witness) of the new moon crescent. Once confirmed, we are instructed in scripture to blow a trumpet at the new moon, allowing the entire world to know that the new moon has arrived.
Some prefer to conduct sightings strictly from the land of Israel (click here for a similar calendar based on Israel sightings). We feel that this approach ignores eyewitness testimony (trumpets) from any other region (this is not instructed within scripture). Just as we do not delay the start of our day until sundown geographically within Israel, there is no scriptural support to delay the start of our month until the crescent is seen geographically within Israel, either.
Traditionally (since the fourth century A.D.), the calendar has been calculated (instead of being observed). This was primarily due to the fact that Israel was forced out from the land and believed calculation was the only alternative. However, this was originally only because the Aviv barley would no longer be readily available (which was geographically required according to scripture) in order to know when the year began. This calculation consisted of an average 19-year Intercalation cycle of alternating 12 & 13 month calendar years. It is much later that this "calculation" would eventually include the computation of moon cycles (based on what is known as the Molad) and additional rules of postponement (called Dechiyot) that would, after hundreds of years, develop into the modern-day Hebrew Calendar. These calculations (including the Molad and Dechiyot) are simply not found within scripture.
Today, now that Israel is no longer completely in exile, there is no reason why we should not restore the method of observation and stop relying on man-made calculations. And for those of us still living outside of the land, we should not neglect the instruction given to us to blow a trumpet at the new moon - a global trumpet call! As witnesses, we can let the world know of the Biblical calendar and Yehovah's appointed times.
This calendar is adjusted based on actual witness confirmation of the new moon crescent. If you would like to report a sighting in your area, please submit your reported sighting via email.
