Guest guest Posted July 18, 2001 Report Share Posted July 18, 2001 AUM SRI GURUVE NAMAH Dear Narasimha! Please clarify one of my doubt. I understand from a solar year to be the time taken by the Sun to come to the point of the zodiac, where it was before traversing 360 deg. Thus one solar year could be time taken by the Sun to move from lets say 0 deg Aries to 0 deg Aries. However, if we have taken one years lengths to be 365.2425 days, can't we say that 1 solar day = 365.2425/360= 1 day 20min 58.2 secs., thats the traversing of Sun through one degree in the zodiac. If the Sun's motion in the zodiac is uniform, the solar day equivalent to the above mentioned figure should be true. In such circumstances, there is no need of finding time based on proportion of Sun's longitude. However, you have given the option of 365.2425 as well as solar year based on Sun's transit. From this can I infer that Sun's motion in the zodiac is not uniform?. Regards Sarajit On Wed, 18 Jul 2001 pvr wrote: > Dear Visti, > > > p.s.

From this can I infer that Sun's motion in the > zodiac is not uniform?. Yes of course. Sun's motion during one day may be 0.9 degrees and may be 1.04 degrees on another day. His motion is non-uniform. If we use the angle swept by him as a measure of time, it becomes a true solar year (360-degree year). The 365.2425-day years are a good approximation for this, but not exactly. Low level divisions of dasas and also dasa pravesh charts of mahadasas and antardasas will change. The difference in dates can in some cases be of the order of days!! The same thing holds for 360-tithi years. A tithi is a time in which Moon-Sun longitude differential changes by 12 degrees. This may be 23 hours on one day and 25 hours on another day. It is non-uniform. Though there is a misconception that traditional pundits use simple procedures, I know of traditional pundits of India who compute longitudes by hand and find exact division of time for fine predictions. May Jupiter's light shine on us, Narasimha Quote Link to comment Share on other sites More sharing options...
