Ayanamsa calculation is of high importance for planetary positions, divisional charts, Dasas, transits, etc. Switching the Ayanamsa can result in major changes in Dasa balance (e.g. for quite sensitive Kalachakra Dasa) or high level Varga charts like Shastiamsa (D-60).
If we calculate the same chart e.g. with Lahiri and Raman Ayanamsa, we can get a difference in Vimsottari Dasa balance of 2 years, Kalachakra Dasa will be completely different, and Shastiamsa charts will have no common planetary positions.
There are different opinions about the correct Ayanamsa. The main stream versions of Ayanamsa in Vedic astrology differ about 1:30 degrees. This section exposes the most important versions of Ayanamsa, compares them and gives examples for the effects on Dasa balance.
