In Vedic Astrology there are nine type of time concepts and different calculation methodology in the ancient texts related to Astrology, which called Nava Vidha Kal Maan. However, among the nine concepts three types of time concepts are directly related to common people, which have greater use in our day to day life.
The first one is Savan Kal Maan, which is based and related to the Sunrise i.e. the time period between one Sunrise to the next Sunrise called Savan Divas or Savan Day. In this way different part of the world would get different Savan Day according to the Sunrise of any particular place.
2. The second one is Chandra Kal Maan or lunar time concept, which is based on the movement of fastest planet Moon. The time period spent by Moon to transit through one Nakshatra called Lunar Day and when planet Moon completes one cycle of 27 Nakshatras then it is called completion of one Chandra Masa or one Lunar month.
3. The third one is Soura Kal Maan or Solar Time Concept, which is based on the transit of planet Sun. Therefore, when planet Sun completes the movement of 360 degrees or transit through twelve zodiac signs then there would be completion of one Soura Varsha or solar year and the time period of transit of Sun through one zodiac sign is called Soura Masa or solar month. Since there are 30 degrees in each zodiac sign so, the time period of transit of Sun through one degree of any zodiac sign is called Soura Divas or Solar Day.
According to the above explanation of Solar time concept, planet Sun has completed one full cycle through 12 Zodiac signs and has entered in Aries on 14th April 2009 at 00:45:46 hrs as per IST. Since planet Sun is the greatest source of energy for all of us as well as for all other planets , this is of special significance in our day to day life. Therefore, I will try my best to give a brief explanation or analysis of the Vedic Astrology chart of the 14th April 2009 at 00:45:46 hrs on our life. I would also give a comparative analysis of two charts i.e. of current year's Solar chart's with last year's solar chart of 13th April 2008 at 18:29:00 the time of entrance of Sun in to Aries in 2008.
