Two weekdays out of seven is the tightest screen anywhere in this cluster, and it is what makes first wearing a rudraksha the narrowest window of the twelve.

Rahu goes through your houses in reverse and takes about 19 months over each one. It is also direct on a quarter of all days, which is not what anybody says about it.

Everything people quote about Saturn timing is an average, and Saturn is the planet where the average hides the most. It holds one sign for 793 days and another for 1,014.

Two windows disqualify a date in every muhurat rule there is. Measured against a real year, both are considerably smaller than the fear attached to them.

Stack every restriction in a panchang and almost no time survives. Here is how the limbs are actually weighed against each other.

A launch wants speed and a company wants to last. The rule asks for both, and the way it does that says something useful about how muhurat rules are built.

Muhurat is the one branch of Vedic astrology that looks forward rather than back. Here is what it screens for, and how much of a year actually gets through.

Amrit, Shubh, Labh and Char are good. Kaal, Rog and Udveg are not. Those seven names are the seven planets, and the split is their own.

Abhijit is the exact middle of the daylight, seven muhurtas either side. It is almost never 48 minutes and almost never centred on 12:00.

Travel is the only activity in this cluster carrying a second and completely independent rule, and it is about where you are going rather than when you leave.

Eleven karanas fill the sixty half-tithis of a lunar month. Seven repeat eight times each, four appear once, and the arithmetic is exact.

Rahu Kaal is an eighth of the daylight, so it stretches and shrinks with the season. And unlike its two companions, it cannot be derived from a planet.
