When the Sun moves from one sign to the next, it exists for a short time in a transitional state.Its diameter is a half degree, and it moves about a degree per day, so for about a day every month, it will partly be in the previous sign and partly in the next.If you were born between April 15th and 26th, you enjoy doing for others, especially for family and friends but try to keep this in check.
When any planet is on a line, it is considered to be on a cusp, but the Sun's cusps and those of the ascendant are most dramatic in their effects.
On the positive side, let's go on to the next cuspoid." Signs next to each other are the most difficult to blend but also the most rewarding when they can be blended to work together. Aries is the most explosive fire sign while Taurus is the most productive earth sign.
Aries is Cardinal and must be on the move as a pivotal point for turning in all directions. This is a power which is difficult to use effectively.
It will also make a difference what we are talking about on the cusp.
If it is the Sun, it is likely to give Aries more support.Even if your Sun is not quite 'cuspy,' you might feel as if it is.
