Dear Friends,
We hope you had a nice Yom Teruah and want to send you an update regarding the crescent moon observation on Saturday, 12 September 2026.
To remind you, on 12 September 2026 the percentage of the moon’s illumination was high, however the lag time was short, meaning that the crescent was very close to the bright horizon, making it a very difficult observation. That being said, we knew from past observations with similar stats, that the moon was far enough along in its cycle that it would be visible, if the horizon was relatively clear from atmospheric obstructions, the observer was looking in just the right place, and had very good vision.
Below is an updated list of positive observations from Israel on Saturday, 12 September 2026:
* Jerusalem (Gilo) at around 7:10pm by Yehosheva Rapuano and shortly thereafter by Tirzah Rapuano. Yehosheva stated “Wearing my glasses, I saw a line in the clouds. I removed my glasses and could still see it without visual aid. The cloud shifted and masked my view of it. A few minutes later the cloud dissipated and it appeared slightly below where I had seen it previously, but this time I could only see it with binoculars. Tirzah Rapuano stated “Looking with the naked eye, under the cloud I saw a slight sliver, a white very very dim line. When I looked away and looked back at it I could see it again. It looked like a crescent but very dim. A few minutes later I confirmed the sighting, seeing it clearly with binoculars I definitely saw the moon without any visual aid.” [A third person wasn’t unable to see the crescent (even with binoculars), despite looking where they were pointing.]
* Ma'ale Adumim by Roy Hoffman with binoculars at 6:48pm, with the naked eye at 6:54pm, he then followed the crescent until it started to set behind the mountains at 6:58pm. Roy stated “The Moon was very faint and difficult to see but I am sure that I saw it several times in the same position.”
* Two other people saw it with binoculars only.
In summation, it’s our understanding that the Biblical Month begins with the crescent moon, i.e. when the moon is far enough away from the sun that it can be visible to the naked eye from Israel, which it was on 12 September 2026 (the end of the 29th day), and therefore the beginning of the 7th month.
For those that asked about beginning the month the following evening (13 September 2026), the percentage of illumination that evening was 7.20%, which is extremely high, i.e. not the beginning of the lunar month.
There’s no photo of the crescent moon from Israel on 12 September 2026. However, at the top of this report is a photo taken by Yosheva Rapuano with a circle indicating approximately where he saw the crescent that evening.
On behalf of all of us who keep the Biblical Calendar, we want to thank everyone who looked for the crescent New Moon from Israel and sent us their observations.
