Kali Yuga Era (Kalyabda) (爭鬥時紀元)

THE KALI YUGA ERA (Kalyabda) — the zero point of ALL classical Indian astronomy: the count from 17/18 February 3102 BC (Julian), the moment tradition places Krishna's departure and Aryabhata's school chose as the computational origin of the cosmos. Every siddhantic planetary theory and every traditional panchāng's 'Kalyabda' counts from this instant; 2026 CE stands in Kali 5127. THE EPOCH IS DERIVED, NOT RECITED: the canonical Julian Day 588466 falls straight out of the catalogue's own Julian machinery, asserted at load — with the two schools' six-hour seam (Aryabhata's Ujjain-sunrise audayika vs the midnight ardharatrika) served, neither crowned. ARYABHATA'S OWN ANCHOR IS THE JEWEL: 'when sixty times sixty years had passed of this Kali age, twenty-three years had elapsed since my birth' — 3600 − 3101 = 499 CE, one sentence from fifteen centuries ago simultaneously dating the verse, his birth (476 CE = Kali 3577) and the era, both identities laws. The 4:3:2:1 yuga arithmetic (432,000 through the 4,320,000-year mahāyuga) asserted. HONESTY: the epoch was COMPUTED backwards for a mean grand conjunction that modern astronomy shows only loosely — a convention of genius, named as one; the elapsed-year regional new-year turns disclosed. Indian becomes thirty-four. Pure compute, no LLM.
