Choghadiya: a local day-and-night timing cycle

Choghadiya uses seven recurring names: Amrit, Chal, Labh, Shubh, Udveg, Kaal and Rog. The weekday determines which name begins the daytime and night-time sequence, then each sequence continues through its own traditional order. The eighth period repeats the first name in that cycle.

The names are a traditional shorthand, not a diagnosis of a day or a person. In the companion calculation, Amrit, Labh and Shubh are shown as supportive; Chal is neutral and often associated with movement; Udveg, Kaal and Rog are shown as caution periods for major new starts.

Day Choghadiya runs from local sunrise to local sunset. Night Choghadiya runs from that sunset to the next local sunrise. They do not borrow a fixed clock timetable, and their traditional sequence is not simply the daytime list carried forward unchanged.

That separation matters for readers planning an evening event or an early departure. A time listed as supportive in daylight does not automatically describe the corresponding hour after dark. Check the day or night label shown for the selected local date.

Each daytime period is one eighth of the actual daylight span, and each night-time period is one eighth of the actual night span. Longer summer days create longer day segments; shorter winter days create shorter ones. The difference can be pronounced away from the equator.

A fixed list of times copied from another date or city therefore loses the logic of the method. A local calculation starts with the real sunrise, sunset and next sunrise for the selected place, then divides those spans into equal local segments.

Method note: Anantrix uses local solar events and the weekday’s traditional starting position to build eight day and eight night Choghadiya periods. If reliable sunrise or sunset cannot be calculated, it shows the periods as unavailable rather than inventing standard clock times.

Use the labels as a calm planning aid, not as an instruction to cancel ordinary life. Safety, caregiving, travel conditions, contractual commitments and urgent needs have priority over a traditional preference.
