Chaughadiya cuts the daylight into eight named parts and the night into eight more. Four names are auspicious and three are to be avoided, and the weekday decides which one opens your day.
Calculating…
Each is one eighth of the daylight, so its length follows sunrise and sunset rather than the clock — nearer a hundred minutes at midsummer and nearer seventy in midwinter. The night parts are the mirror: long when the day parts are short. So the familiar “about ninety minutes” is an average and not a rule, and a table printed for one city is wrong for yours by however far apart the two sunrises are.
The names run in an unchanging cycle — Udveg, Chal, Labh, Amrit, Kaal, Shubh, Rog — and the weekday decides where that cycle begins. The day runs the cycle forward one name at a time; the night runs it five at a time, which is why the two tables below look unrelated even though they use the same seven names. Because eight parts are cut from a seven-name cycle, the eighth repeats the first, and the next day starts somewhere else again. That is why the same name falls at a different hour every day, and why the pattern is worth reading rather than memorising.
This page counts it auspicious; a number of almanacs treat it as neutral instead. The name means moving, and the reading that follows from that is the practical one: it suits things already in motion — a journey continued, an errand, a message sent — more than it suits a beginning. Where a source you trust says neutral and you are choosing a moment that matters, the honest course is to wait for Amrit, Shubh or Labh rather than to argue the point.
Both cut the same daylight into eight, but they answer different questions. Rahu Kaal, Yamaganda and Gulika each name ONE part to avoid and say nothing about the rest. Chaughadiya names all eight, good and bad alike, which is why it is the method people actually plan a day around. They can overlap, and when they do this page shows both rather than hiding one — an auspicious Chaughadiya inside Rahu Kaal is a judgement call, and it is yours to make.
Rahu Kaal names one part to avoid and says nothing about the rest. Chaughadiya labels all sixteen, which is what makes it useful — you are never left without an answer — and is also where it goes wrong. Sixteen labels in a day is not sixteen instructions. The names are a convention for choosing between hours that are otherwise equal, not a schedule a day has to be lived to, and a day made entirely of Udveg and Rog is an ordinary day with ordinary hours in it. As everywhere else here, the timing is arithmetic and follows your own sunrise; which name a part carries is the tradition's reading of it. The sixteen parts and their categories were checked against a published almanac and agree — with the single exception of Chal, above.
