Choghadiya for Chennai, Tamil Nadu

The day from sunrise to sunset is divided into eight, and the night into eight more. Each part carries the quality of the planet it belongs to. Nothing here is a prediction; it is the same division a printed almanac gives, for this place and this date.

Each part says whether it is good. Where Rahu kalam, Yamagandam or Gulikai falls on a part, the part carries that name instead, because it comes first: start nothing new in it, whatever the choghadiya.

Char is a good period, and the one for setting out on a journey.

The eight parts are eighths of the real day and the real night, so they are different lengths except at the equinoxes and every boundary matches a published almanac. Which name falls where is not arbitrary either: the day begins on the weekday's own planet and steps through them in the order the horas run, and the night begins on the fifth planet from that one. Seven names across eight slots is why the first one comes round again at the end.
