Matsya Purana — Measures of Time: Caturyuga Computation
चत्वारि नियुतानि स्युर् वर्षाणि तु कलिर्युगम् द्वात्रिंशच्च तथान्यानि सहस्राणि तु संख्यया एतत्कलियुगं प्रोक्तं मानुषेण प्रमाणतः //
catvāri niyutāni syur varṣāṇi tu kaliryugam dvātriṃśacca tathānyāni sahasrāṇi tu saṃkhyayā etatkaliyugaṃ proktaṃ mānuṣeṇa pramāṇataḥ //
Kali-yuga consists of four niyutas of years, and additionally 32,000 years by count. Thus this Kali-yuga is stated according to the human measure of time.
It does not describe Pralaya directly; it establishes the human-year duration of Kali-yuga, which is part of the broader Purāṇic framework used to situate events leading up to periodic dissolutions.
By defining Kali-yuga’s span, it frames the ethical context in which kings and householders must uphold dharma amid decline—an emphasis common in Purāṇic guidance even when the verse itself is purely chronological.
No Vāstu or temple-ritual rule is stated in this verse; its significance is chronological—useful for dating ritual calendars and Purāṇic historical timelines rather than prescribing architectural practice.
