Where everything is
The Moon is new, invisible beside the Sun; the tradition reads it as the quiet start of a lunar month.
Sun is at 29°52′ Sagittarius in the tropical zodiac, 5°39′ Sagittarius in the sidereal, gate 10 line 2 in Human Design. The tradition associates Sun with authority, health and where one stands on one's own account.
Moon is at 15°44′ Capricorn in the tropical zodiac, 21°31′ Sagittarius in the sidereal, gate 54 line 1 in Human Design. The tradition associates Moon with mood, appetite and what is needed rather than wanted.
Mercury is at 13° Sagittarius in the tropical zodiac, 18°47′ Scorpio in the sidereal, gate 5 line 2 in Human Design. The tradition associates Mercury with talking, writing, negotiating and the paperwork nobody enjoys.
Venus is at 25°59′ Sagittarius in the tropical zodiac, 1°46′ Sagittarius in the sidereal, gate 11 line 4 in Human Design. The tradition associates Venus with relationship, comfort, money and taste.
Mars is at 4°41′ Capricorn in the tropical zodiac, 10°28′ Sagittarius in the sidereal, gate 58 line 1 in Human Design. The tradition associates Mars with effort, friction and the willingness to force a thing through.
Jupiter is at 22°40′ Cancer in the tropical zodiac, 28°26′ Gemini in the sidereal, gate 62 line 3 in Human Design, and retrograde; a Jupiter retrograde is read as growth consolidating rather than spreading. The tradition associates Jupiter with growth, teaching and the widening of things.
Saturn is at 25°38′ Pisces in the tropical zodiac, 1°25′ Pisces in the sidereal, gate 36 line 4 in Human Design. The tradition associates Saturn with structure, limit, work and time.
Uranus is at 28°16′ Taurus in the tropical zodiac, 4°03′ Taurus in the sidereal, gate 8 line 5 in Human Design, and retrograde; an outer planet is retrograde for months at a time; the tradition reads it as the theme turned inward. The tradition associates Uranus with the sudden, the unconventional and the break with what was.
Neptune is at 29°25′ Pisces in the tropical zodiac, 5°11′ Pisces in the sidereal, gate 25 line 2 in Human Design. The tradition associates Neptune with what is blurred, longed for and dissolved.
Pluto is at 2°25′ Aquarius in the tropical zodiac, 8°11′ Capricorn in the sidereal, gate 41 line 1 in Human Design. The tradition associates Pluto with what is buried, and what is forced up.
Rahu is at 11°38′ Pisces in the tropical zodiac, 17°25′ Aquarius in the sidereal, gate 63 line 1 in Human Design. The tradition associates the nodes with appetite and the unfamiliar; Ketu, opposite it, detachment and endings.
In Human Design
The Sun is in gate 10, the behaviour of the self, line 2, the Hermit line: the gate the whole day is read through, and the line it sits on. The Moon is in gate 54, ambition, line 1, the Investigator line, and moves on within hours. Each gate has its own page in the library: gate 10 and gate 54.
The Moon's line changes, 21 December 2025, UTC
| 01:34 | 38.2 | the fighter |
| 03:26 | 38.3 | the fighter |
| 05:16 | 38.4 | the fighter |

Times in UTC. A line is a sixth of a gate, a little under a degree; the Moon crosses one every hour or two. Where the Sun's gate is the day's theme, the tradition reads the Moon's as the hour's, and neither is a forecast.
Tight aspects at noon
Venus square Saturn, 0.3° from exact and opening: friction between the two, which is where the work is.
Sun square Neptune, 0.5° from exact and opening: friction between the two, which is where the work is.
Uranus sextile Neptune, 1.1° from exact and opening: an easy opening between the two.
Mercury square Rahu, 1.4° from exact and opening: friction between the two, which is where the work is.
Within two degrees of exact, one for the Moon. Closing means the aspect is still tightening; opening means it has passed. The slow pairs stay for weeks and the Moon's pass in hours.
Why the two zodiacs disagree about everything above
Every body sits about 24 degrees earlier in the sidereal zodiac than in the tropical one.
Western astrology anchors its zodiac to the seasons and Vedic astrology to the stars, and the two have drifted 24.22 degrees apart. That is why a Western page and a Vedic one can name different signs for the same planet on the same day, and why neither is wrong. We show both, every time, and where a reading depends on which one was used we say so.

A sign change or a station is a condition beginning or ending. The tradition reads the condition; it does not read an event into it, and neither does this page.
