Velkovski suggested that the orbit of the earth (or orbit of the sun or if you prefer

) took exactly 360 days. Then around 700B.C the calenders changed, and he suggests that this is when there was a disturbance of the orbits of the planets, resulting in all sorts of change. I recall him talking about venus streaming across the sky, linked to the myth of Medusa story of the goddess turned crazy. The god of war, Mars, came very close to us in its orbit relasing electrical disharge between it and us hence it's name. After this the orbit became 365 and a quarter days. Initially these 'extra' days were viewed with 'suspicion' (in Velkovski's words!), as not belonging to the rest of the year. The extra days would be more or less the days between Christmas and new year. Funnily enough I have always felt like these are odd days, as if they didn't belong to the rest of the year.
In addition, there was an 'inbetween' period whilst everything settled down into what we have today. At one point the moons orbit was 35/36 days, at which point we had 10 months in the year. Evidence of this still exists in the names, Sept = 7, Oct = 8, Nov = 9, Dec = 10, July and August the two months added later (Julius Ceaser and Caeser Agustus?) after the moon settled into its current orbit.
The way I look at it our realm has been distorted from what it should be by some past event. I imagine a radio station at 360Hz but I have a faulty receiver which only allows to tune as close as 365.25Hz. I would still hear the station (experience our reality) but with a little distortion/interference. Also it would be possible that another radio station, at say 369Hz, could also be heard at times over the other station. This could explain a lot of paranormal observations! I guess from a creationist point of view 360 days makes a lot more sense, where as from the mainstream science 'it all happened by accident' 365.25 days is just the sort of figure they want to prove their point. It would also make more sense from a flat earth perspective that our realm would be finely tuned to 360 days and 30 days for the sun and moon. From the standard cosmology it would seem an incredible coincidence to have exactly 360 days, they wouldn't like that idea at all.
You could also link this to the 432Hz vs 440Hz sound comparison, designed to slightly distort what we experience, without it being too obvious and giving the game away.
Some good info on the 360 day year here, with some key bits copied and pasted below link
Even though this was as late as 238 B.C., still with great pomp the Egyptians would
write, of "
the year of 360 days and the 5 days added to their end..."
The setting aside of the last five days agrees with the practice which Herodotus [~440 B.C.; and see
below] ascribes to the Egyptians of considering the five days over the 360 as scarcely belonging to the year, and not placing them in any month.
Mayan astronomers [made] detailed observations of Venus, leading to a highly accurate calendar." Mayans had varying interrelated calendars but to identify an actual date in history, they used the Long Count calendar of 360-day years. The Maya demonstrated tremendous mathematical skill with their base 20 number system and a representation of their number system in Arabic numerals shows that 1 = 1; 10 = 20; 100 = 400; and 1000 = 8000. However, in a telling departure, transliterating (so to speak) the Mayan Long Count calendar into Arabic numbers results in 1 = 1; 10 = 20; 100 = 360; 1000 = 7200 (rather than 8000); and 10000 = 144,000 (rather than 160,000). This modification of the number system is a stunning fact of ancient history (reminiscent of the
Sumerian number system anomaly from far across the ocean). Most worldviews simply cannot account for such extraordinary history. Because many deem an historical, actual 360-day year as a physical impossibility, dramatic worldwide evidence to that effect gets ignored or discounted.
Archaeology well attests the ancient use of twelve 30-day months in Mesopotamia.
Then in about 1550 B.C.,
The Ebers Papyrus, written during the reign of Pharaoh Amenophis, presents a 360-day year calendar on the
reverse side of the first "page" of the 66-foot long scroll. (The lengthy document preserved many Egyptian medical practices for posterity including their knowledge of the heart as the center of one's blood supply with its vessels extending throughout the body.) And in the 1200s B.C., Pharaoh Ramesses II had engraved an
astronomical ceiling depicting a 360-day year.
Aztec Calendar Stone: 12-feet in diameter, the Aztec calendar stone has its Ring B of 18 quincunxes which combines with the 20 uinal day signs for a 360 day year.
India Calendar: Encyclopedia of
Indo-Aryan Research, G. Thibaut,
states: "All Veda texts speak uniformly and exclusively of a year of 360 days. Passages in which this length of year is directly stated are found in all the Brahmanas." Thibaut further states that the Vedas (1500 - 500 B.C.) never mention intercalary days.
Sumerian Calendar: The resulting system... which without question complemented throughout the 3rd millennium natural, lunistellar divisions, is attested in its basic form of a twelve-month, 360-day year in the archaic documents from the end of the 4th millennium [B.C.].
From a maths perspective: 360 is thus divisible by many numbers including those especially helpful (in bold, even today) for calendars and timekeeping:
2,
3,
4, 5,
6, 8, 9, 10,
12,
15, 18, 20,
24,
30, 36, 40,
45,
60, 72,
90,
120, and
180. A year of 360 days is reasonably divisible even by the 2 equinoxes, 2 solstices, four seasons, 12 months, etc.,
24 hours in a day, 24 time zones of 15 nominal degrees each, 60 minutes in an hour, and 60 seconds in a minute. Consider also our comfort using a "dozen" and with 12 inches in a foot, and 36 inches in a yard. Even in major construction, the Babylon sexigesimal (base 60) mathematics beat the Greeks to trigonometry by 1500 years; it was easier to use; and according to the journal
Science, was even
more accurate than today's modern trigonometry.
Babylonian Calendar: The Babylonians inherited from Sumeria the relationship between the calendar and the number system with the 12-month, 360-day year giving rise to base 60.
Roman Calendar: Written within a decade of 115 A.D., Plutarch's
Life of Numa states: "during the reign of Romulus [claimed 753-716 B.C.], they had been irrational and irregular in their fixing of the months, reckoning some at less than twenty days, some at thirty-five, and some at more; they had no idea of the inequality of the annual motions of the sun and moon, but held to this principle only, that the year should consist of three hundred and sixty days."
The setting aside of the last five days agrees with the practice which Herodotus ascribes to the Egyptians of considering the five days over the 360 as scarcely belonging to the year, and not placing them in any month. So completely were these five days considered by the Romans to be something extraneous, that the soldier appears to have received pay only for 360 days.
John wrote of 1,260 days (3.5 * 360) in Revelation
11:3 &
12:6, which equals exactly the three and a half (360-day) years that he mentions in Revelation
12:14. That number also exactly equals the 42 months of Revelation
11:2 and
13:5. These year and month equivalents are exactly equal, and only equal 1,260 days, when calculating with months of 30 days each.
