दशानयनाधिकाराध्यायः
आद्या दशा तस्य परा परेषान्तत्षष्ठषष्ठक्रमतोखिलानाम् ॥शराप्ततष्टन्तु गताभिधानमेष्यन्तु तद्बाणविशुद्धशेषम् ॥ ३ ॥
Its period comes first. Then come the others, each the sixth from the one before, for all. The remainder after dividing by five is called the passed part. Five less that remainder is the part to come.
Simple meaning: Kalahora order: the current hour lord first, then every sixth planet. The remainder gives the parts passed and to come.
उभे तु वर्षाद्रि ७ बलेन निघ्ने शरोकृतेस्तंगतगम्यमाने ॥
Kalahora periods: the first lord's period is split into a part to come, at the start, and a part passed.
परा परेषान्तु यथास्थितास्स्युर्गतोन्मिता चेति दशा हि तस्य ॥
Kalahora periods: the others keep their full share; the first lord comes back at the end. Month and day use their own spans.
अत्रोदाहरणम् ॥ तत्र श्रावणवदि नवर्म्यां शुक्रवासरे उदयाद्गतघटीपलेषु ५।३६ वर्षप्रवेशः । तत्र रविः ३।९।३६ दिनमानं ३३।३०
Kalahora example: the year starts on a Friday in Shravana, 5 ghatikas 36 palas after sunrise. The day is 33;30 long.
