Default Daylight Saving Time

It seems that playing fast and loose with the English language or even torturing it comes at a price as followers of the early 20th century theorists have lost the capacity to put the back and forth motions of the planets and satellites around the parent Sun or parent planet using the normal language of motion to the left or to the right.

The rule of thumb is that a planet or a satellite, as we see it from Earth, moves from left to right in front of the parent object and from right to left as it travels behind it. This restores context after to losing it to RA/Dec modelling.

This response mostly belongs in the other thread however this thread and so many other are connected within a larger and more expansive narrative. It is fitting that the effect of daily rotation in isolation brings the Sun into view each weekday hence the 24 hour cycle as an average is anchored in natural noon whereas the orbital motion of the Earth anchors the annual cycle with the first seasonal appearance of a star. It generates the inviolate proportion of days/rotations to years/orbital cycles in such a way as a format can be created based on a continuous stream of rotations.

DST is perhaps unnecessary from an astronomical standpoint but it only makes sense in how it alters the relationship of timekeeping to daily rotation and orbital motion in two ways.
