Based on this article I have drawn one up on paper
**** Gann taught students to watch anniversary dates with past market tops and bottoms for a change in trend. When it came to shorter term analysis of time,
Gann devised a system of counting off time in solar degrees of a year from past market tops and bottoms.
He counted divisions of the year in eighths and thirds.
When clusters of time counts from past tops and bottoms highlighted a future date, that date was significant for a reversal of trend.
The cycle of one year has 365 days. The circle of one year has 360 degrees.
To explain, there are 4 cardinal points in the circle, 90, 180, 270 and 360 degrees.
As the Earth moves around the Sun the daylight hours progressively get longer and shorter every six month.
The shortest day of the year in the southern hemisphere is June 21 and is know as the Winter Solstice (this is the 90 degree point). The longest day of the year is December 22, 270 degrees, the summer solstice. September 21 (180 degrees) and March 21 (360 degrees) are the days when daylight and darkness are equal, these are the Equinoxes. The four seasons of the year evolve around these 4 points.
It is important to realise that the Earth takes 179 days to move from 0 degrees to 180 degrees around the Sun. Yet, it takes 186 days to move from 180 degrees to 360 degrees around the Sun. The two points in the circle, of one year, where the relationships between days and degrees begin speeding up and slowing down are the perigee and the apogee. The perigee (distance to the Sun is closest) occurs about January 3 each year, the apogee (distance to the Sun is furthermost) occurs July 4 each year.
When comparing cycles it is preferable to work in degrees for greater accuracy, for this you need to use an ephemeris, capable of calculating degrees precisely ++++++++
Dam interesting theory for some of the old blue chips with lots of data
