Why the two zodiacs disagree by ~24°

The tropical zodiac is anchored to the equinox, while the sidereal zodiac is anchored to the fixed stars. Because Earth's axis precesses, the two have drifted apart by roughly 24° — the ayanamsa — growing about 50 arc-seconds per year. Which correction to use is a school choice: Lahiri is the Indian and Sri Lankan government standard, Raman a popular alternative, and Fagan–Bradley the Western sidereal value. This converter applies each to the same arc-minute tropical positions so you can compare charts across systems.
