The biblical Hebrew lunisolar calendar
First month: Nisan or Abib(in the Bible) (March-April)(30 days)
Second month: Iyyar or Ziv(in the Bible) (April-May)(29 days)
Third month: Sivan(May-June)(30 days)
Fourth month: Tammuz(June-July)(29 days)
Fifth month: Ab(July-August)(30 days)
Sixth month: Eloul(August-September)(29 days)
Seventh month: Tishri or Ethanim(in the Bible)(September-October) (30 days)
Eighth month: Hesvan or Bul(in the Bible) (October-November)(29 or 30 days)
Ninth month: Chislev(November-December)(29 or 30 days)
Tenth month: Tebeth(December-January)(29 days)
Eleventh month: Shebat(January-February)(30 days)
Twelfth month: Adar(February-March)(29 or 30 days)
Thirteenth month: Adar II or Veadar (29 days)
The lunar year has 12 months of 29 or 30 days. The intercalary month (Veadar) is regularly added to compensate for the difference of 11 days between the lunar year (354 days) and the solar year (365 days). In this case, this year has exceptionally 13 months, it is a “lunisolar”. In the Bible there is no direct mention of this process in order to adjust the lunisolar calendar to the solar year. Nevertheless, indirect information shows that this adjustment was made. For example, some months had to coincide regularly with seasonal crops, either spring (Abib (Nisan): spring) or autumn (Ethanim (Tishri): autumn) (Exodus 23:15). It is obvious that the Israelites of the biblical times realized this adjustment by the addition of the intercalary month (Veadar). The festivals celebrated the month in spring, remained spring, over the years. And all the autumn festivals of the month of Tishri, remained autumnal, over the years (Leviticus 23:37).
Currently the adjustment system, used by the Hebrew calendar, is made with a “metonic cycle”: 7 adjustments with 7 lunisolar years of 13 months, over a period of 19 years.
After careful reading of all the prophetic texts mentioning the "Day of Jehovah" or the "Great Tribulation", it can be said, without a shadow of a doubt, that this day will last only ONE DAY
The clearest prophetic text over its duration is that of Zechariah and the Book of Revelation, both of which describe the Day of Jehovah as one day, or the
only date of one day:
"And it will become one day that is known as belonging to Jehovah. It will not be day, nor will it be night; and at evening time there will be light" (Zechariah
This text alone shows that it is a 24-hour day, and not a period of few days, because it is written that at the time of day, it will be neither day nor night, and that at the
time of evening there will be light. However, the most explicit text is that of the book of Revelation, where this Day is connected with a date on the Jewish calendar. In Revelation 11:18, it is written: "But the nations became wrathful, and your own wrath
came, and the appointed time came for the dead to be judged and to reward your slaves the prophets and the holy ones and those fearing your name, the small and the great, and to bring to ruin those ruining the earth" (Revelation 11:18). This text refers to
the time of the Great Tribulation, when God "will bring ruin to those who ruin the earth". However, what is even more interesting, is that verse 19 repeats this time in enigmatic way, connecting the Day of Jehovah withe the vision of the ark of his covenant:
"And the temple sanctuary of God in heaven was opened, and the ark of his covenant was seen in his temple sanctuary. And there were flashes of lightning and voices and thunders and an earthquake and a great hail" (Revelation 11:19).
This verse has two main parts: The first is the vision of the "ark of his covenant", the date of only one day. Indeed, Jehovah God did not allow to see the ark of his covenant (by the high priest), any day other than
Ethanim (Tishri), 10 (Leviticus 16:2,29). The second part of the verse 19, is the symbolic description of the Great Tribulation. The Ethanim, 10 (Tishri), corresponds to the dramatic celebration of the Day of Atonement. The process of celebration is described
in Leviticus chapter 16. It is a dramatic moment, because it describes symbolically, what will happen during the Day of Jehovah, the Great Tribulation. It will be a day of sadness, because Jehovah had given this instruction regarding this day: "It is a sabbath
of complete rest for you, and you should afflict yourselves. It is a lasting statute" (Leviticus 16:31) (REALITY OF THE
THE GREAT TRIBULATION WILL TAKE PLACE IN TISHRI 10TH
the vision of the "ark of his covenant", the date of only one day. Indeed, Jehovah God did not allow to see the ark of his covenant (by the high priest), any day other than Ethanim (Tishri), 10
“And the temple sanctuary of God in heaven was opened, and the ark of his covenant was seen in his temple sanctuary. And there were flashes of lightning and voices and thunders and an earthquake and a great hail”
This famous date of Tishri 10th appears in the Bible, several times, in an encrypted or symbolic way, in direct and indirect relationship with the prophetic descriptions of the Great Tribulation (The month of Tishri is the seventh month of the Hebrew lunisolar calendar, between the months of September/October) (Names of months of the Hebrew Calendar):
“In the 25th year of our exile, at the beginning of the year, on the tenth day of the month, (…) By means of visions from God, he brought me to the land of Israel and set me down on a very high mountain, on which there was a structure like a city to the south” (Ezekiel 40:1a,2): The prophet Ezekiel has a vision of the earthly administration of the Kingdom of God, after the 7 months of purification immediately following the Great Tribulation, Nisan 10th (Ezekiel 39: 12-16 ; 40:1a “at the beginning of the year (Nisan), on the tenth day (10th) of the month”). If we add the intercalary month Veadar, in accordance with metonic cycle, we have exactly the date of TISHRI 10th. The prophetic information about the 7 months, in Ezekiel 39: 12-16 shows that the Great Tribulation will happen in a lunisolar year of 13 months.
“Do not be afraid of the things you are about to suffer. Look! The Devil will keep on throwing some of you into prison so that you may be fully put to the test, and you will have tribulation for ten days. Prove yourself faithful even to death, and I will give you the crown of life” (Revelation 2:10): The mention of the symbolical 10 days of tribulation, after which the disciples of Christ have their reward of everlasting life, seems to evoke the 10 days of Tishri, mentioned later in Revelation 11:19 (Numbers in the Bible). In Tishri 10th, all of the 144,000 and the Great Crowd will be permanently sealed for everlasting life, in the Heavens for the group of 144000, and on Earth for the Great Crowd (Revelation 7).
The law on the Jubilee stipulated that this proclamation had to be made by a powerful sound of a horn, on Ethanim (Tishri), 10. This powerful sound of horn or trumpet, is described by the apostle Paul, as being the beginning of a heavenly resurrection: "because the Lord himself will descend from heaven with a commanding call, with an archangel’s voice and with God’s trumpet, and those who are dead in union with Christ will rise first. Afterward we the living who are surviving will, together with them, be caught away in clouds to meet the Lord in the air; and thus we will always be with the Lord" (1 Thessalonians 4:16,17). This heavenly resurrection will be before the great tribulation, corresponding to the death and the instantaneous resurrection of the remnant of the 144,000, on earth, which will go to heaven, before the great tribulation, and which are the earthly remnant of 7,000 (actually): "And in that hour a great earthquake occurred, and a tenth of the city fell; and seven thousand persons were killed by the earthquake, and the rest became frightened and gave glory to the God of heaven" (Revelation 11:7-13).
will happen in summer and in winter”
In the former interpretation of this biblical verse (on this site), it was written that Ethanim (Tishri), 10, corresponding to the Jehovah's Day (the great tribulation), should exactly correspond to the passage, from summer, to the autumn equinox, depending on the solar calendar system on September, 23. However, this interpretation is an anachronism in the biblical context. Why? If there were very old solar calendars in that times, they were not used in the Hebrew and biblical lunisolar calendar system (and even less the Julian and later the Gregorian calendars (used in the Western Part of the World). Consequently, to link the date of an Ethanim (Tishri), 10, in a Biblical lunisolar calendar system, with a September, 23, of a Gregorian solar calendar system, is a real anachronism...
The expression "It will happen in summer and in winter", must be understood in an otherwise. In fact, this expression is used in a different way (but synonymous), in another part of the Bible, referring to the day of the festival of booths: "And you will celebrate your Festival of Weeks with the first ripe fruits of the wheat harvest, and the Festival of Ingathering at the turn of the year" (Exodus 34:22). The Festival of Weeks alludes to the Pentecost of Sivan, 6, in the spring season. Festival of Ingathering, alludes to the day of Festival of Booths, in the autumn season, linked with this famous "turn of the year". By making the connection of this last expression, with that of Zechariah 14:8b, it is likely the Ethanim (Tishri), 15, of the Lunisolar calendar. It was the official passage from summer, to winter (autumn), without taking into account the astronomical autumn equinox of a solar calendar (September, 23), which did not exist in the biblical times (Hebrew). Of course, to find out the necessity to add an intercalary month, currently called Veadar (Adar II), they must take into account the number of days following the Ethanim, 15, the official change of season, with the day when they could observe the equality between the day and night (the observed astronomical equinox). This important aspect of the lunisolar calendar is in an another page.
The context of Zachariah 14, justly alludes to the Festival of Booths: "Everyone who is left remaining out of all the nations that come against Jerusalem will go up from year to year to bow down to the King, Jehovah of armies, and to celebrate the Festival of Booths. But if anyone among the families of the earth does not go up to Jerusalem to bow down to the King, Jehovah of armies, no rain will fall on them. And if the family of Egypt does not come up and does not come in, they will have no rain. Instead, they will have the scourge with which Jehovah scourges the nations that do not come up to celebrate the Festival of Booths. This will be the punishment for the sin of Egypt and the sin of all the nations that do not come up to celebrate the Festival of Booths" (Zechariah 14:16-19).
Zechariah Chapter 14, both alluded to Jehovah's Day, the great tribulation, with the dramatic events that result from it (see verses 14:1-7,12-15). These dramatic events will take place on Ethanim (Tishri), 10, during the planetary fulfillment of the Atonement Day, the great tribulation. This celebration was dramatic and sad (Leviticus 16:29-31). On the other hand, Zechariah 14:8b, is to be put in the context of the Festival of the Booths: "In that day living waters will flow out from Jerusalem, half of them toward the eastern sea and half of them toward the western sea. It will happen in summer and in winter". The "living waters" is a joyful, soothing situation, as Earthly Paradise. This situation is to be linked to the context of the Festival of Booths, a joyful moment: "Seven days you will celebrate the festival to Jehovah your God in the place that Jehovah chooses, for Jehovah your God will bless all your produce and all that you do, and you will become nothing but joyful" (Deuteronomy 16:15, to compare with Zechariah 14:8-11,16-19). If in one hand, the date of Ethanim (Tishri), 15, is no doubt in the context of Zechariah 14, in the other hand, that of Ethanim (Tishri),10, maybe, appears in a much less obvious way. It could be the allusion to the holiness of God: "In that day the words ‘Holiness belongs to Jehovah!’ will be written on the bells of the horses. And the cooking pots in the house of Jehovah will be like the bowls before the altar" (Zechariah 14:20). The celebration of the Day of planetary Atonement, the Great Tribulation, will be the celebration of the Holiness of God. But also it will be the complete disappearance of the "Canaanite": "In that day there will no longer be a Canaanite in the house of Jehovah of armies" (Zechariah 14:21)... Understand who can...
Can we know?
"Keep on the watch, therefore, because you do not know on what day your Lord is coming"
"Certainly unless you wake up, I will come as a thief, and you will not know at all at what hour I will come upon you"
These two biblical quotes, show that it is advisable to answer, depending on the context. The answer of the first biblical quote, is that we cannot know the moment or the date of the Great Tribulation, while the second text suggests that this ignorance will not be permanent, so as not to be surprised.
Sometimes the Bible, in the same chapter, expresses the thesis and the antithesis of a situation: "Do not answer the stupid one according to his foolishness, so that you do not put yourself on his level. Answer the stupid one according to his foolishness, so that he does not think he is wise" (Proverbs 26:4,5). The verse 4 is a thesis that makes it clear, in certain situations, it is advisable not to respond to a stupid man, in order to avoid the snare of being discredited, by lowering oneself in the level of his stupidity. The verse 5 is an antithesis, which shows that in a different context, someone can be in the duty to respond to the stupid, in order to put him in front of his own foolishness. It is the insight, that makes it possible to understand the nuances of an answer to a situation, or to a specific question (Hebrews 5:14).
The different approaches to the question above are the following: in the current state of things, there is no certainty on a possible date. However, that does not mean that Jehovah God and his Son, Jesus Christ, will constantly leave us in this uncertainty: "For the Sovereign Lord Jehovah will not do a thing unless he has revealed his confidential matter to his servants the prophets" (Amos 3:7). There are biblical teaching points that allow the date, to be fixed in a kind of year (which is currently not known with certainty): the Ethanim (Tishri), 10, and the kind of year, lunisolar year of 13 months (Apocalypse 11:19 (Tishri, 10); Ezékiel 39:14 (seven months of earth cleaning); 40:1,2 (Nisan, 10)). However, it is not enough.
In order to target this information, in a specific year, we must see the simultaneous fulfillment of prophecies that converge on this date and specific year. This is why there is no certainty. In doing so, the only way of observation is to use the biblical information, on the date and the kind of year, comparing with the observed fulfillment of the prophecies. By presenting a “landmark date”, without necessarily saying that it will be the date of the Day of Jehovah, it will be compared with the progress of the worldwide events, to understand the possible convergence with this day and specific year (the landmark date)... Here is the landmark date, that is to say the closest to biblical standards (understood):
Tishri, 10, 2026
Saturday evening, after the sunset in Jerusalem,
September 19, to Sunday, September 20, 2026
(New Astronomical Moon)
It has only a benchmark value (it will not be qualified as the date of the Day of Jehovah (great tribulation)), in order to proceed to the gradual observation of world events, with regard to both, of the biblical prophecies and this landmark date. Updates will be made when there will be significant global events. They will be announced on the home page of the site (as it is the case currently).
As for the Official Date of the Yom Kippur 2026, it will take place on the basis of the religious (or ecclesiastical) new moon (the new religious moon is based on the Chiourim calendar (French edition)), September 20, 2026 (one day late). Here is also the dates of the years 2024 and 2025, regarding the Ethanim (Tishri), 10, based on the new astronomical moon and the new religious moon (with 1 or 2 days late): Ethanim (Tishri),10, 2024: October 10/11, 2024 (new astronomical moon); October 11/12, 2024 (new religious moon). It should be noted that on the basis of the year 4026 BCE, a traditional date of the year of creation of the man Adam, the year starting with the autumn of 2024, to the autumn of 2025, will be jubilee and will represent the year 6050, of the existence of man on earth, according to the biblical chronology (Genesis 2:7). Ethanim (Tishri),10, 2025: September, 29/30, 2025 (new astronomical moon); October 1/2 2025 (new religious moon). The years, 2024/2025 and 2025/2026 will not be lunisolar. The year, 2026/2027 will be a lunisolar year (with the intercalary month of Veadar (or Adar II)).
These details are given in order to demonstrate that all the interpretative options are taken into account and the earlier the kingdom of God will be established on earth, better that will be (Matthew 6:9,10)... As for the list of the biblical prophecies linked with the Day of Jehovah (Great Tribulation), here are the main:
The comments of these articles will be regularly updated, as the worldwide events are evolving, and at the same times bringing us irretrievably closer, to the Day of Jehovah (Joel 2:1). It is necessary to continue to be patient in the waiting for Jehovah God: "Good it is to wait in silence for the salvation of Jehovah" (lamentations 3:26). "But as for me, I will keep on the lookout for Jehovah. I will show a waiting attitude for the God of my salvation. My God will hear me" (Micah 7:7).
