Graha Chart

Solar system configuration for (default) Auckland

Calculations are based on average speed of grahas/celestial objets (planets) and based on center of sun/moon/planets. Some use appearance as start of events. Light takes time to reach earth. Also appearnce is based on refraction, parallex errors and so on. So results may vary from other systems.

For force or energy effect of grahas on humans, actual distance matters, not how it appears. There will be parallex error, time for light to travel etc, when we view grahas.

Some key constants

January 1, 4713 BCE Noon is Julian 0
Sun (or earth around sun) moves 0.985608372105459 deg/day 59.1365023263275 min/day
The mean sidereal year is the time taken for the Earth to complete one revolution of its orbit, as measured against a fixed frame of reference (such as the fixed stars). Its average duration is 365.256363004 days at the epoch J2000.0 = January 1, 2000, 12:00:00 TT).
The mean tropical year is defined as the period of time for the mean ecliptic longitude of the Sun to increase by 360 degrees. Since the Sun's ecliptic longitude is measured with respect to the equinox, the tropical year comprises a complete cycle of the seasons. Because of the Earth's axial precession, this year is about 20 minutes shorter than the sidereal year 365.24219 (365.24219878) days.
The mean anomalistic year is the time taken for the Earth to complete one revolution with respect to its apsides. The orbit of the Earth is elliptical; the extreme points, called apsides, are the perihelion, where the Earth is closest to the Sun (January 5, 07:48 UT in 2020 sun at 260.27528 from star aswin), and the aphelion, where the Earth is farthest from the Sun (July 4, 11:35 UT in 2020). The mean anomalistic year is 365.259636 days
Moon around earth 13.1763585909097 deg/day 790.581515454582 min/day
1 lunar month = 29.5305861853113 days
1 star month = 27.3216608 days (Time for one orbit of the Earth = 27.32166 days)
1 Anomalistic month 27.554550 days (time between perigees and precesses in 3232.6054 days or 8.850578 years). The minimum and maximum extremes in orbital eccentricity are 0.0255 to 0.0775 and the extremes in the length of the anomalistic month are 24.629 days to 28.565 days.
1 Draconic month 27.212221 days (with respect to the ascending node and precesses in 6793.4765 days or 18.5996 years)
One light-year is about 9.461 trillion km.

Eclipse

The Sun, Earth, and Moon form two similar triangles: one with Earth blocking the Sun and one with the Moon blocking the Sun. The Sun's light is projected into space as a converging cone of umbra and a diverging cone of penumbra.
Approximate radius of the Earth's umbra: Ru = (Re * dm) / (Rs - Re)
Lunar Eclipses occur during Full Moon when the Moon passes through the shadow of the Earth.
The Earth's umbra is ~1.4 Million km long
Moon diameter 3,475 km and speed = 3,685 km/hour
Umbra's width is 9000 km and Moon's and takes around 2.5 hours to cross.
Earth's umbra is not totally dark because of light scattered by the Earth's transparent atmosphere. This gives the fully eclipsed Moon a slightly ruddy appearance (think about how the Sun looks reddish at sunset or sunrise).
Solar eclipse, when Ketu, Sun and Moon are very close
Lunar eclipse, when Ketu & Sun and Rahu & Moon are very close

Kali Yuga

According to the Surya Siddhanta, Kali Yuga began at midnight (00:00) on 18 February 3102 BCE. According to the astronomer and mathematician Aryabhata, Kali Yuga started in 3102 BCE. He finished his book Aryabhattiyam in 499 CE, in which he gave the exact year of the beginning of Kali Yuga. He writes that he wrote the book in the "year 3600 of the Kali Age" at the age of 23. As it was the 3600th year of the Kali Age when he was 23 years old, and given that Aryabhata was born in 476 CE, the beginning of the Kali Yuga would come to (3600 - (476 + 23) + 1 (One year from 1 BCE to 1 CE)) = 3102 BCE.
According to K. D. Abhyankar, the starting point of Kali Yuga is an extremely rare planetary alignment, which is depicted in the Mohenjo-daro seals. Going by this alignment, the year 3102 BCE is slightly off. The actual date for this alignment is 7 February 3104 BCE.

Length of a day

The length of a day is the time it takes for the planet to complete one full rotation on its axis —24 hours or 86,400 seconds on average. But in reality, each rotation is slightly irregular due to a variety of factors, such as the gravitational pull of the moon, seasonal changes in the atmosphere and the influence of Earth’s liquid core. The discrepancy of just milliseconds that doesn’t have any obvious effect on everyday life.
However these discrepancies can, in the long run can affect satellites and telecommunications. So, the smallest time deviations are tracked using atomic clocks, which were introduced in 1955. Atomic clocks count the oscillations of atoms held in a vacuum chamber within the clock itself to calculate 24 hours to the utmost degree of precision. We call the resulting time UTC, or Coordinated Universal Time, which is based on around 450 atomic clocks.
Astronomers also keep track of Earth’s rotation — using satellites that check the position of the planet relative to fixed stars, for example — and can detect minute differences between the atomic clocks’ time and the amount of time it actually takes Earth to complete a full rotation.
In 1972, after decades of rotating relatively slowly, Earth’s spin had accumulated such a delay relative to atomic time that the International Earth Rotation and Reference Systems Service mandated the addition of a “leap second” to the UTC. This is similar to adding a day to the leap year.
The shortest-term changes in Earth’s rotation, come from the moon and the tides. Similarly, the Earth’s liquid core has also been slowing down, with the solid Earth around it speeding up.
