Creating the Sarvatobhadra Chakra (SBC) in Excel: A Comprehensive Guide
Introduction
The Sarvatobhadra Chakra is a unique and powerful tool in Vedic Astrology used for predictive analysis. Unlike standard birth charts (Rashi charts) that focus on planetary positions, the SBC focuses on the interaction between Nakshatras, Vowels (Swaras), and Consonants. It is primarily used to determine the impact of planetary transits on an individual or an event.
7. Important Caveats
- Authenticity: The classical mapping of Tithis, Nakshatras, etc. to row/col offsets varies slightly by regional tradition. Verify your source.
- Complexity: Some advanced versions weigh each factor (e.g., Tithi has 2x weight). Start simple.
- Mercury (4): Always double-check Mercury's placement with a classical astrologer for critical events.
To build this in Excel, you must arrange the astrological factors in a clockwise manner around the border and inner layers: DV Publication Outer Layer: Houses the 28 Nakshatras (including Abhijit). Second Layer: Contains the 12 Zodiac Signs (Rasis). Third Layer: Lists the Tithis (Lunar days) and Weekdays (Varas). Fourth Layer: Displays specific Sanskrit vowels (Swaras).

- Planetary positions (e.g., Sun, Moon, Ascendant)
- Zodiacal sign associations
- Personal details (e.g., birth date, time, place)
- Inputs: Date, Time, Timezone offset, Longitude, Latitude (for precise lunar/nakshatra calc).
- Calculate Julian Day Number (JDN) — use formula in cell (example):
=DATE(year,month,day) + (hour + minute/60)/24 + 2415018.5 - 0
- Get Moon longitude & nakshatra index using simplified mean-motion formulas or import accurate ephemeris (recommended: connect to an API or precompute table).
- Map 27 nakshatras into 8-pada SBC positions (3 or 4 nakshatras per pada). Use INDEX/MATCH to place nakshatra labels.
- Place grahas by calculating their zodiac positions, then map into SBC cells.
- Conditional formatting rules:
