Image GenerationFreemium

EphemerisDial precomputes the full annual equation-of-time offset table for any longitude and overlays analemmatic correction marks on dial plates with sub-millimeter positioning accuracy. Users upload existing dial designs as SVGs and receive corrected output with the equation-of-time curve rendered as an elegant inlaid figure-eight. Historical analemma variants from Greek, Islamic, and Renaissance traditions are available as style overlays.
