During the Tamil month of Aadi (July-August 1996), the Vakya system often placed Amavasya (new moon) and Pradosham (Shiva worship days) one day later than the Drik system. This is due to the Vakya system’s use of mean motion (ignoring the Moon’s equation of center). For orthodox Srauta rituals in 1996, followers of Vakya exclusively observed these days as sacred, creating a visible divergence in temple festival dates across Tamil Nadu.
The 1996 almanac prominently featured the Vikramarka Vakyas —a set of 247 stanzas attributed to King Vikramaditya’s court. Each Vakya corresponds to a specific day of the year. For instance, the Vakya for Thai Poosam (January 1996) was consistently repeated as it had been for centuries, disregarding the actual lunar parallax. This exclusivity means that for a given Tamil date in 1996, the Rahu Kalam , Yamagandam , and Gulika periods—derived from Vakya output—differed from all other panchangams. vakya panchangam 1996 tamil exclusive
