There are two versions of Oahspe verses identifying the old and new year's days which end and start a Kosmon year.
(1) The 1882 edition of Oahspe, the Book of Sethantes XIII:13 (the footnote to the contrary), and the Book of Inspiration XIV:2-3, both state that the north line of the sun (Tropic of Cancer, June 21) is old year's day, with the day following being new year's day.
(2)All subsequent renditions of these verses, wherever found, were changed by Dr. Newbrough to reverse the meaning, so that the shortest day of the year in the northern hemisphere (south line of the sun, Tropic of Capricorn, December 21) should be the old year's day, with the day following the new year's day. The first revision appeared in the 1884 Gospels of Oahspe which included the Book of Inspiration; one word was changed in XIV:3, to revise the start of the sun's travel from "southern" to "Northern". The second changes were to both verses XIV:2-3, and these first appeared in Dr. Newbrough's Kosmon Almanac calendar for 37 A.K. (1885) which he produced for the Shalam colony in New Mexico. These almanac changes were then incorporated (with many other changes throughout the entire book) in the second edition of Oahspe printed in 1891.
Dr. Newbrough's view that the calendar should end/start with the northern hemisphere's winter solstice (Dec. 21) was clear from the outset in his footnote at the bottom of page 30 of the 1882 Oahspe, pertaining to Sethantes XII:35 ("*In all systems of religion, the revelations attribute the change of watch of the Gods and Lords to be on that day of the year next after the shortest day in the northern hemisphere, which is the cosmological new year's day."). The actual text of the 1882 Oahspe indicates the opposite (the shortest day in the southern hemisphere, when the sun is at the northern line).
The only explanation ever put forward for this particular revision was that the first edition 1882 Oahspe version had "printer's errors". However, the Book of Sethantes XII:13 and Book of Inspiration XIV:2 are separated by many many other books, yet they remain consistent with each other (and both had to be revised in order to make December 21 the end/start of the Kosmon year).
When the real College of Prophecy/Children's colony occurs, the true prophets of that day will determine the correct calendar for scheduling the community activities in concert with the third resurrection. To date, none of the attempts to form a permanent colony have succeeded (which isn't to say the December 21 calendar they used was in itself, the problem).
Chapter XIV of the Book of Inspiration in Oahspe describes the construction of the Faithist calendar. There have been three versions of the key verses (Inspiration XIV:2-3). For the benefit of readers with one edition of Oahspe (either 1882 or 1891 based), all three of these versions are reproduced, along with the change in 1891 to the Book of Sethantes XIII:13. In general, Faithists have used the December 22 new year's day, according to Dr. Newbrough, as the basis of their calendar year. Here is how Oahspe was changed, in this regard:
Version #1 - 1882 Oahspe indicated June 22nd New Years
Book of Sethantes XIII:
13. Behold, this day have I set apart as a new day in heaven and earth; because on this day the sun taketh his course from the north line; and from this time forth it shall be called the new year's day. So shall it be, from this time forth, the day of the relief watch in Hored (heaven).
Book of Inspiration XIV:
2. The northern line of the sun shall be the end of the year, and it shall be called the last day of the old year, saith Jehovih.
3. And the first day thereafter, when the sun starteth on his southern course, shall be the beginning of the year, and it shall be the new year's day.
The 1882 edition of Oahspe described the end of the Kosmon year as being on the "northern line of the sun", and new years being the day after. What was the meaning of this? The answer is found in the Book of Fragapatti XIX:1, describing the location of the heavens over North Guatama (United States): "A thousand miles north of the northern line of the sun." Hence, the northern line of the sun is what we know as the Tropic of Cancer, the line being 23 1/2 degrees northern latitude, which occurs at the summer solstice, the longest day of the year in the northern hemisphere, and nominally occurs every June 21st (see the accompanying map of the heavens over Guatama, illustrated from Fragapatti XIX:1).
PROBABLE REASONS FOR THE CALENDAR REVISION TO OAHSPE
Spiritual times and seasons do not necessarily follow mortal ways of doing things. Kosmon, and all arcs, for example, start with the dawn of new knowledge (light) on the earth, which is the reverse of the world's calendars (which start at the beginning of a dark age). It is possible that the spiritual year does not follow mortal conventions; certainly the calendar starting in June as described in the 1882 Oahspe did not.
Dr Newbrough (as most Faithists since) did not agree with the summer solstice, June 22nd beginning of the Kosmon year, as indicated by the 1882 Oahspe. He probably reasoned as others have, that since the Kosmon month begins with the new moon, with full moon being mid-month, the year should begin with a new sun, with full-sun (summer) being mid-year. For the same reason, noon is mid-day. (Ignoring, of course, that our brethren living in the southern hemisphere, i.e., Africa, South America, Australia, etc. have winter starting on June 21; proving that northern hemisphereans have dictated the calendar construction.) He may have also reasoned that since Oahspe says that Kosmon began with the spiritual manifestations at Hydeville, Rochester, New York, on March 31, 1848, then the first year of Kosmon began on December 23, 1847. (The sun entered Capricorn on December 22, 1847; according to this reasoning, the last day of Seffas.) So when the Book of Inspiration was printed next, in the 1884 "Gospels of Oahspe" booklet, he changed one word in Inspiration XIV:3 from "southern" to say "Northern".
Version #2 - 1884 Gospels of Oahspe, change to December 23rd New Years
Book of Inspiration, Chapter XIV (one word changed in verse 3):
2. The northern line of the sun shall be the end of the year, and it shall be called the last day of the old year, saith Jehovih.
3. And the first day thereafter, when the sun starteth on his Northern course shall be the beginning of the year, and it shall be the new year's day.
In addition to this one word change to verse 3, Dr. Newbrough wrote the following notes about the Kosmon calendar in "The Publisher's Remarks on the Book of Inspiration, in the 1884 Gospels of Oahspe:
"As to the calendar referred to in this book, we have here generalized it for the benefit of Faithists.
"Kosmon, first day of first year, the same as December 23, 1847. 35 A.K., 1st day, equals December 23, 1882 (i.e., 1883). December 22nd equals Holy sabbath, or old year's day. One week thereafter equals the second sabbath day. These are the sabbath days (0 being old year's day): 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133, 140, 147, 154, 161, 168, 175, 182, 189, 196, 203, 210, 217, 224, 231, 238, 245, 252, 259, 266, 273, 280, 287, 294, 301, 308, 315, 322, 329, 336, 343, 350, 357, 364 or 0. In leap year, two contiguous sabbaths anecede New Year's day (i.e., two days are Holy sabbath in a leap year)."
Version #3 - 37 A.K. (1885) Kosmon Almanac, December 23rd New Year's Day
(Same as appeared later in the 1891 second edition of Oahspe.)
Book of Sethantes XII:13
13. Behold, this day have I set apart as a new day in heaven and earth; because on this day the sun taketh its course for the Hadan (north) line; and from this time forth it shall be called the new year's day. So shall it be, from this time forth, the day of the relief watch in Hored.
Book of Inspiration XIV (both verses changed this time)
2. The shortest day on the northern line of the sun shall be the end of the year, saith Jehovih.
3. And the first day thereafter, when the sun on his southern course starteth towards the north, shall be the beginning of the year, and shall be called new year's day.
THE OAHSPE CALENDAR REVISIONS PROBABLY INTENDED
Knowing what the "northern line of the sun" means in Oahspe from the Book of Fragapatti XIX:1, the correct revisions to change the beginning of the year from June 22nd to December 22nd, would have been as follows:
Book of Sethantes XII:1
13. Behold, this day have I set apart as a new day in heaven and earth; because on this day the sun taketh its course from the south line (day after Tropic of Capricorn line, December 22nd); and from this time forth it shall be called the new year's day.
Book of Inspiration XIV:
2. The southern line of the sun (Tropic of Capricorn, December 21st) shall be the end of the year, and it shall be called the last day of the old year, saith Jehovih.
3. And the first day thereafter, when the sun starteth on his northern course, shall be the beginning of the year, and it shall be called new year's day.
THE NUMBERING OF KOSMON YEARS
In general, the enumeration of After Kosmon years (A.K.) in Oahspe, follows Dr Newbrough's identification of the first Kosmon year beginning on December 23, 1847 and ending on December 22, 1848 (i.e., 1 A.K. = 1848 A.D.).
AFTER KOSMON YEAR NUMBERING
To convert Christian calendar Anno Domini (A.D.) years to After Kosmon (A.K.) years, use the following formula:
Christian year A.D. minus 1848 - Faithist year A.K.
BEFORE KOSMON YEAR NUMBERING
For reasons unknown, the enumeration of years Before Kosmon (B.K.) in Oahspe do not use the same reference year, as After Kosmon years. The reference for all years Before Kosmon (B.K.) in Oahspe is the Christian year 1850 A.D. Hence, the formula to convert Christian calendar Anno Domini (A.D.) years before 1848 A.D. to Before Kosmon (B.K.) years, use the following formula:
1850 minus Christian year A.D. = Faithist year B.K.
Another formula is required to convert Christian calendar years Before Christ (B.C.) to Before Kosmon (B.K.) years:
Christian year B.C. plus 1850 = Faithist year B.K.
THE FALLEN SWORD'S DAY (FREEDOM'S DAY) - JANUARY 1ST
This day remembers the day in the year 15 A.K. (1863) when President Lincoln issued his Emancipation Proclamation, which freed all slaves in the United States forever more, and signifies that the pen is mightier than the sword.HOLY VEIL DAY (ES or SPIRIT DAY) - MARCH 31ST
This is in remembrance of the day that Jehovih's angels manifested (knocked) and communicated with mortals (the Fox family) at Hydeville, near Rochester, New York, on March 31, 1848, signifying "Heaven Unveiled". Although there were other spiritual communications prior to 1848 (by Jehovih's enemies), this day marked the official start of Jehovih's angels communicating with mortals, at the beginning of Kosmon.HOLY COMPACT DAY (U.S. CONSTITUTION DAY) - JUNE 21ST
This holy day commemorates the ratification, signing and sealing of the Constitution of the United States of America, as it founded a government separated from the influence of any religion or church (separation of church and state), the beginning of religious liberty for all mankind on earth. The United States constitution was ratified on June 21st, 1788, which is the Holy Compact Day. Although the nation's citizens celebrate the day of the first signing of the Constitution, on September 17, 1787, Faithists celebrate the day the Constitution became official, upon ratification (signed and sealed).HOLY KOSMON DAY (FIRST COVENANT DAY) - Yet to Come
This day will be set aside to commemorate the first successful covenant of a community of persons to Jehovih, for the purpose of establishing the College of Prophecy which will become the foundation for Jehovih's kingdom on earth. Such a covenant first occurred on July 26, 1884, entered into by Dr. Newbrough and the volunteers who assembled at the pre-colony site, Pearl River, Rockland County, New York. These covenanters attempted to establish the Shalam colony prophesied in Oahspe, and did participate in a commune near Las Cruces, New Mexico starting in October, 1884, but it failed (as have all similar attempts since). To this day, the real covenant day, which will result in the true College of Prophecy commune (and true foundation of Jehovih's kingdom on earth), has not occurred.FUTURE FAITHISTS WILL CLEAR EVERYTHING UP
By establishing the College of Prophecy (also known as the Children's Home, or a family, colony, commune or community of Faithists), and therein developing the senses of suis and ethe, will the confusion resulting from the various changes, revisions, omissions and imperfections of the current Oahspe texts be cleared up. For the true prophets (who will graduate from this college) will not only recover the complete original Oahspe from the libraries of heaven, but also write new revelations of their own, surpassing all others that have ever been.
