Good question! Here is my understanding: Yes, as far as the Best Days, which are based on astrology, the dates might differ if it were based on sidereal astrology rather than tropical, as the position of a sign currently differs between the two systems, with tropical currently being ahead of sidereal by about 24 or so degrees. In tropical, the names of the zodiac signs pertain to 30-degree segments along the ecliptic that were named for constellations present in those positions hundreds of years ago. In sidereal astrology, the signs relate to the actual positions of the constellations, which have shifted because of the slow wobble of Earth’s axis (precession) changing our perspective. The dates of the tropical signs basically do not change over the years, whereas those of sidereal signs will change over time. Therefore 鈥淭aurus,鈥 for example, might occur on different days, depending on which system is used.
