In May 1926, John Alden Knight put together some fishing folklore and other fishing factors such as the sun and the moon, hence the name Solunar (Sol for sun and Lunar for moon) to form a theory on the patterns of animal movement. Knight compiled a list of factors which control or influence the day-to-day behavior of many freshwater and ...
Most sun charts plot azimuth versus altitude throughout the days of the winter solstice and summer solstice, as well as a number of intervening days.Since the apparent movement of the Sun as viewed from Earth is nearly symmetrical about the solstice, plotting dates for one half of the year gives a good approximation for the rest of the year.
The Toledan Tables, or Tables of Toledo, were astronomical tables which were used to predict the movements of the Sun, Moon and planets relative to the fixed stars. They were a collection of mathematic tables that describe different aspects of the cosmos including prediction of calendar dates, times of cosmic events, and cosmic motion. [2]
Newcomb's Tables of the Sun (full title Tables of the Motion of the Earth on its Axis and Around the Sun) [a] is a work by the American astronomer and mathematician Simon Newcomb, published in volume VI of the serial publication Astronomical Papers Prepared for the Use of the American Ephemeris and Nautical Almanac.

In astronomy and celestial navigation, an ephemeris (/ ɪ ˈ f ɛ m ər ɪ s /; pl. ephemerides / ˌ ɛ f ə ˈ m ɛr ɪ ˌ d iː z /; from Latin ephemeris 'diary', from Ancient Greek ἐφημερίς (ephēmerís) 'diary, journal') [1] [2] [3] is a book with tables that gives the trajectory of naturally occurring astronomical objects and artificial satellites in the sky, i.e., the position ...
The best known of these is the Tabular Islamic calendar: in brief, it has a 30-year cycle with 11 leap years of 355 days and 19 years of 354 days. In the long term, it is accurate to one day in about 2,500 solar years or 2,570 lunar years. It also deviates from observation by up to about one or two days in the short term.
This progression involves moving the natal chart forward one day for each year of a person's life. So, for example, a person born on April 2, 1982, would have a progressed chart for 2007 drawn up based on the position of the planets on April 27, 1982 (i.e. 25 days for 25 years).
