The annual cycle

depicts the concept of cyclic, eternal Time without start and beginning (cf. About Time concepts) and the lunar-solar positions in Space and Time.

The most ancient cosmic worldview (–link- cf. Ancient Cyclic Calendars) is transformed through current techonology to a modern, internet reality.

The solar and lunar positions, which regulate by definition the earthly calendar, are illustrated in their mutual relation for every day on the Annual Cycle. The names of the months, which are placed initially according to our conception (ouranio home page), appear by mouse hovering over the cycle. Summer light and warmth belong to the upper part – winter darkness and cold to the lower part. The clockwise direction is identified with the usual one of the clocks.

But this specific representation of the Annual Cycle is not imposed naturally; it is adjusted according to the personal user conception through three choices, which appear by clicking on the picture of the Earth (or the Sun):

  • the view of Cosmos from Earth (geocentric) and from outside, from the solar system (heliocentric),
  • the position of the 1st month of the Gregorian Calendar (January) in upper or lower part of the cycle,
  • Time direction – clockwise or counterclockwise.

The current date for the solar and lunar positions appears in the right part of the cycle (or beneath it for mobile devices). The user can select each day in the next 10 years by clicking on a «magic» button.

GEOCENTRIC

A permanent calendar, with Earth as center, which represents the lunar and solar position for every day of the year.

The colours symbolise the season changes. The temperature of the colours corresponds to every season: warm colours for summer, cold for winter etc. A popup menu comes forward by clicking the solar or lunar icon on the right. Common elements for both Sun and Moon are the time of rising and setting (according to user position on Earth), as well as the position on zodiac cycle (=zodiac sign). The current moon phase can be also read.

HELIOCENTRIC

A cyclic representation with the Sun at its center. The circumference of the cycle symbolises the orbit of Earth (which is in reality an ellipse) and of the Moon (an epicycloid curve). The Moon orbit is not depicted in true scale (as well as every of the other distances in the graphic interface). Nevertheless, it refers to the real motion of Moon in Space (cf. Real motion of Moon) and represents faithfully in time new and full moon dates by its extremal points on the curve (as well as the moon phases through the colour gradient).

The blue dot, which shows the Earth position, moves on the Annual Cycle according to personal, user selection: clockwise or counterclockwise. The year beginning is the one of the Gregorian Calendar. A point of discontinuity between the last day (31st December) and the first of next year (1st January) illustrates the fundamental moon problem in a solar calendar: The quotient of the solar months to the moon months is not an integer.
