Back to “The Dates of the LORD’s Holidays”

Calendar Table for 2017 AD to 2034 AD

This table is for the years 2017 to 2034. The 1st column of each year on the left is the standard Gregorian calendar with month, day, and year. The next column is “Event & Angular Separation” which will have the LORD’s holidays or Jewish’s holidays and fast days listed. The “Angular Separation” is that of the Sun and the Moon as seen from the Earth. There is a time when the Moon is dark. The Danjon limit is the smallest angular separation between the Sun and the Moon when the first light of the Moon can be seen [ref]. (A Danjon limit of 7 is used in these calculations with a limit below 7 possibly seen [have to have two witness see it though] but not affecting most months.) If a number higher than 7 is listed, it is possible to see the 1st light of the Moon, but most likely the first light will not be seen due to the clouds or pollution in the sky. A number of 9 could be seen better with a number of 10 or greater being mostly seen depending on the eyesight and experience of the person. The 1st day the light of the Moon is seen is considered the Rosh-Chodesh/New-Moon and starts the counting for the Biblical Hebrew month. The next two columns labeled “Month (B)” & “Day of Month (B)” are the numbers of the predicted Biblical Hebrew month and day. The next column is the “Day of the Week” with a 1 standing for the 1st day of the week as listed in the picture/table below. A Hebrew day goes from sunset to sunset (Lev 23:32). So, every holiday, event, or fast will start at sunset on the day before it is listed.

The Jewish authorities at this time start the counting of Hebrew months not by the first light of the Moon but when the Sun and Moon come together during an astronomical new moon [ref]. The last two columns of each year labeled “Month (A)” & “Day of Month (A)” are the numbers of the Hebrew month and day based on the Astronomical new moon. The “Event” column to the left of these month and day columns is the LORD’s holiday, Jewish holiday, or fast for those dates.

If there are 2 dates for the Rosh-Chodesh/New-Moon, it is because the Danjon limit is to close to predict the exact date (from 7-10). Also, If there are 29 days in a month, the month may have 30 days if the weather does not allow for the Moon to be seen on the 29th day.

Different things can cause a leap month (13th month) to be added [ref]. Leap months are added if the 16th day of the 1st month would occur before the vernal spring equinox (3/19, 3/20, 3/21) [ref: (goto verse 8)]. But, there has to be barley ready to harvest for Yom haBikkurim (Day of the First Fruits) to occur (Ex 9:31; 12:1; Lev 23:9, 10, 11, 12, 13, 14), so barley being ready is the main timing event for the first month of ha’Aviv/ha’Abib (Nisan) [ref]. As some of these years are in the future, there is no way to know for sure when the 13th month is added. These months are best guess.

For what each “event” is about, see The LORD’s Holidays & Dates.

This is the Reference area:

We will be using observations from Yisra’el/Israel from this site to know if the barley is ready for the year.

All data is figured using NASA Jet Propulsion Laboratory: Horizons Systems.
Settings: Ephemeris Type = Observer Table; Target Body = Moon [Luna]; Observer Location = Jerusalem Israel (35°13′59.9″E, 31°46′00.1″N); Time Specification, Step size = 1 hour; Table Settings = custom.
Settings for Rosh-Chodesh/New-Moon: Observer Table Settings = “#23-Sun-Observer-Target-ELONG-angle” (checked), Reference frame = ICRF, Date/time format = calendar and Julian Day Number, Calendar type = Mixed, Time digits = HH:MM, Angle format = sexagesimal format, Refraction model = standard atmospheric refraction model, Range units = km, RTS flag = disabled, (everything else left blank). You could also check mark “#10-Illuminated-fraction” to give you an idea of the Moon’s phase.
Settings for finding spring and fall equinox: (everything the same as above with the following changes); Target Body = Sun [Sol]; Observer Table Settings = “#2-Apparent-RA-&-DEC” (checked) and/or “#31-Observer-ecliptic-lon.-&-lat.” (checked) with all others unchecked. #2 gives you the spring equinox at 24 or 0 and #31 gives you the fall equinox at 360 or 0. #2 gives you the fall equinox at 12 and #31 gives you the fall equinox at 180.
