In Jain daily time-division, each day (from sunrise to sunset) is split into four “kāls,” each spanning four muhūrtas. One muhūrta = 48 minutes.

• Second kāl of the day = 5th to 8th muhūrta after sunrise.
• In simple terms: it is the mid‑day period, from about 3 hours 12 minutes after sunrise up to about 6 hours 24 minutes after sunrise.
• Example: If sunrise is at 6:00 AM, the second kāl runs roughly from 9:12 AM to 12:24 PM.

Usage in practice:

• Shvetāmbara and Digambara traditions both treat this as the mid‑day window; it is traditionally the prescribed time for the daytime (devāsī) pratikraman in the Shvetāmbara tradition. Local calculations may vary slightly based on actual sunrise.
