Two dates to compare
The top-down view shows every planet at both dates side-by-side. Date 1 = the historical / archetypal position you're studying (e.g. 1775-04-26, US founding). Date 2 = the present-day / target comparison. Use the Snapshot recurrence finder below to discover candidate Date 2 values automatically.

Snapshot recurrence — find a date that resembles this layout
Find dates where the selected planets simultaneously (AND across all selected) sit at their Date 1 positions, within tolerance. Date 1 = the target solar-system position (top "Date:" input). Date 2 = an optional search-near date — when set, the closest-in-time matches to Date 2 surface first, instead of every match across the full 340-year range. Use the sidereal (fixed-star) frame for position recurrences — the snapshot search ignores the precession toggle so a 248-y Pluto cycle scores correctly. Click a row to overlay it on the top-down view alongside Date 1.

Degrees from ω Psc — interactive
Each line is the planet's geocentric ecliptic longitude measured from ω Psc, 0-360°. 0° = planet appears at the ω Psc direction in Earth's sky; 180° = opposite side. Two lines crossing means those planets share the same direction in Earth's sky — gravity vectors stack. Lines wrap visually from 360°→0° at each orbital reset (that's just paper-cutoff, not a real jump). Toggle to heliocentric for the Sun-perspective orbital view.
