Twenty-four planetary hours

About / Help

Sunrise-to-sunrise frame. The planetary day begins at local sunrise and ends at the next local sunrise.

Bright and dark. Bright hours run from sunrise to sunset. Dark hours run from sunset to the following sunrise.

Location packets. Manual Location Mode pairs a named place with latitude, longitude, and timezone so historical dates and birth times are not mixed with the wrong local frame.

Moon calendar. The Moon panel uses SunCalc for moon phase, illumination, moonrise, moonset, and above/below-horizon clues for the same selected place and time.

Statements. Each focus statement combines the day ruler as the broad field, the hour ruler as the method, and the ruler's ordinal appearance in the planetary day. The page says “Moon hour,” “Jupiter day,” and so on to keep timing conditions distinct from planets as bodies.

Animated heptagram. The ring keeps the Chaldean order. The hour ruler glows inside the current day. The heptagram advances one day-ruler step per sunrise-to-sunrise day, so the full star is drawn over seven planetary days.
