How to read this table
Day from sunrise, night from sunset
The day column is daylight cut into eight equal parts between local sunrise and sunset. The night column is the eight equal parts between sunset and the next sunrise. Each weekday begins with a different name, then the seven names cycle; night starts from a different name than day. Use the table to see which named watch covers the clock time you have in mind. The colors group Amrit, Shubh, and Labh as favorable; Rog, Kaal, and Udveg as caution; Chal as mixed. That grouping is part of the electional system, not a separate calculation.
