उदाहरणम् ॥ शनिदशादिनानि सौराणि ८४ एषां शैलविश्वांशो दिनादिकः ०।२६।४७ द्विघ्नः १।१३।३४ दशादिवसेषु ८४ युतः ८५।१३।३४ पलेषु ३४ दशादिनानां ८४ क्वग्निभागेन युतः ३६ जातानि शनिदशादिनानि ८५।३३।३६ सौरसावनानि ॥ एवं सर्वेषु दशादिवसेषु सौरसावनता कर्तव्येति ॥
Example. Saturn's period is 84 solar days. Their 137th part, in days and so on, is 0;26;47. Doubled, it is 1;13;34. Added to the 84 period days, it is 85;13;34. To the 34 palas (24-second units), add a 31st part of the 84 period days. This gives 36. Saturn's period becomes 85;33;36 in solar-civil days. Make all period days solar-civil this way.
Simple meaning: Solar-civil example: Saturn's 84 solar days become about 85 days 13 ghatikas in solar-civil days.
