LatitudeLine

Draw precise solar declination arcs for seasonal time indication on any sundial

Image GenerationFree

LatitudeLine computes the exact hyperbolic declination arcs for solstices, equinoxes, and user-defined calendar dates for any horizontal or vertical dial design at a specified latitude. It renders arcs in multiple historical styles—Arabic numerals, zodiac symbols, or month names—drawn from medieval and Renaissance manuscript sources. Output SVGs are compatible with both CNC routing and hand-scribe workflows.
