Hebrew Calendar - Chiourim - September 2023 (Elul / Tishri 5783),
10 Tishri corresponds to September 24/25, 2023 (two days late with the Biblical Tishri 10 (see photo above))
"It will happen in summer and in winter"
Jehovah clearly announces "His One Day" (14:7), the Great Tribulation, will take place in the day
ot the change of season, from the summer solstice to the autumnal equinox (representing the beginning of winter, in the Bible), September 22nd (after the sunset) to 23rd (gregorian calendar). In many biblical quotes, it is known that the Great Tribulation
will take place in Ethanim 10th (Tishri 10th), in a luni-solar year of 13 Biblical months. Regarding Zachariah 14:7,8 : The "one day" of Jehovah, the date of the great tribulation will take place : Tishri 10th = September 22/23.
Starting from these three extremely important Biblical information, it is sufficient to look first in the current Jewish calendar (Hebrew Calendar - Chiourim (written in french)), in what luni-solar year of 13
months, the Ethanim, (Tishri 10), corresponds to the September 22nd and 23rd, the date of the transition from the summer solstice to the autumnal equinox. Based on this official Jewish calendar, we must search until the year 2034, where Tishri 10th exactly
corresponds from Friday, September 22 (after sunset) to Saturday, September 23, 2034.
Regarding the other biblical method based on the astronomical new moon, we get the date from Friday,
September 22 (after sunset) to Saturday, September 23, 2023 (which is a luni-solar year), corresponding to the biblical Ethanim,10 (Tishri,10). How to obtain the Ethanim 1st (Tishri 1st)? We must take into account the annual alternation of lunar months given
its duration of 29 days and a half (this half day must be integrated every other month): a lunar month of 30 days, followed by a month of 29 days, etc. The alternation of the beginning of the biblical year (which begins in Nisan), to the month of Tishri is
the following: Nisan: 30 days , Iyyar (or Ziv): 29 days, Sivan: 30 days, Tammuz: 29 days, Ab: 30 days, Elul: 29 days and Ethanim (or Tishri) 30 days.
To get exactly Ethanim 1st (Tishri
1st) 2023, just start with the new moon of the previous month, Elul 1st, which, given the annual alternation, has only 29 days, which allows to obtain the Tishri 1st. The new moon corresponding to Elul 1st, will be in the day of August 16, 2023 (gregorian
calendar). That means, Elul 1st will begin on August 15th, after sunset, to August 16, 2023. Adding, 29 days, in accordance with the annual alternation, the 29th of Elul will be the in September 12th (after sunset), to the 13th of September 2023.
So, Ethanim 1st (Tishri 1st), in September 13th (after sunset) to September 14th. Therefore, the Biblical Ethanim 10th (Tishri 10th), will be: Friday, September 22nd (after sunset), to Saturday,
September 23rd, 2023.
Comparing this date with the Hebrew calendar Chiourim, there are two days late in this calendar: September 22/23, 2023 corresponds to Tishri 8th. It is the biblical
option of the new moon (without visible crescent) that was chosen for the calculation of the date of 22/23 September 2023 (Psalms 81:3). It is on this same biblical basis of calculation that the date of the next commemoration of the death of Jesus Christ is determined on Sunday, April 5, 2020, after sunset.
