Cyril Fagan relates sidereal to tropica, shifting the boundaries (same as in Vedic astrology).

Whereas Walter Berg devised a system based on 13 signs and variable boundaries.

In 1995, Walter Berg introduced his 13-sign zodiac, which has the additional sign of Ophiuchus. Berg's system was well received in Japan after having his book translated by radio host Mizui Kumi (水井久美) in 1996.

For the purpose of determining the constellations in contact with the ecliptic, the constellation boundaries as defined by the International Astronomical Union in 1930 are used. For example, the Sun enters the IAU boundary of Aries on April 19 at the lower right corner, a position that is still rather closer to the "body" of Pisces than of Aries. The IAU defined the constellation boundaries without consideration of astrological purposes.
