January 4, 2027

In one paragraph

On January 4, 2027 the Moon is in Sagittarius at 7°32' Sagittarius and the Sun is in Capricorn at 13°54' Capricorn. The lunar phase is a waning crescent, 10 per cent illuminated. Jupiter and Uranus are retrograde on January 4, 2027. MyMysticDay computes these positions on its own servers for noon UTC using the lunar and solar series from Jean Meeus’s Astronomical Algorithms and NASA JPL Keplerian elements for the planets, rather than reading them from a third-party ephemeris.

Moon: Sagittarius

The Moon

Sagittarius, 10% lit

The Moon is the fastest body in any chart — roughly half a degree an hour, and two to three days in a sign. It is the reason two consecutive days feel different from one another at all, and the one position on this page that changes materially between morning and evening.

Retrogrades

2 planets retrograde

Jupiter and Uranus are retrograde on January 4, 2027.

A retrograde planet is not reversing. It appears to move backward from Earth because the two orbits are passing each other, the way a slower train appears to slide backward from a faster one. MyMysticDay determines it by comparing a planet’s longitude a short interval apart, so a station is dated to the day it happens rather than read from a table.

The shape of the day, before anybody’s chart

Angles the planets are making to each other on January 4, within half the orb a natal chart would allow — tight enough to be news about a particular day. These are the same for everyone; what differs is which of your own degrees they land on.

The part that is about you

This sky is the same for everyone. Your chart is not.

Every figure on this page applies to all eight billion of us equally. What makes a day yours is which of these degrees is standing on one of your own — and that takes your birth chart, not your sun sign. The daily reading is free and needs no account.

Method

Where these numbers come from

Solar and lunar longitudes follow the standard series published in Jean Meeus’s Astronomical Algorithms; the planets follow NASA JPL’s Keplerian elements with their secular rates, solved for eccentric anomaly and projected onto the ecliptic. Retrograde motion is determined by comparing longitudes a short interval apart rather than assumed from a table. Every figure on this page was computed by this application — no part of it is requested from a third-party ephemeris.

Positions are given for 12:00 UTC. A date is a whole day and the bodies move through it, so noon is the midpoint: the positions shown are the ones true for the largest part of the day across the largest number of time zones. Only the Moon moves fast enough for the choice to change the figure materially.

The full specification — the house system, the aspect orbs, the tolerances the engine is tested against on every deploy — is published on the methodology page. Astrological interpretation elsewhere on this site is presented as a reflective framework rather than as fact; the astronomy on this page is simply arithmetic, and it can be checked against any published ephemeris.

Clear answers

Frequently asked questions

What planets are retrograde on January 4, 2027?

Jupiter and Uranus are retrograde on January 4, 2027. A planet is retrograde when it appears from Earth to move backward through the zodiac. Nothing physically reverses; the appearance comes from the two orbits passing each other. MyMysticDay determines retrograde motion by comparing a planet’s longitude a short interval apart rather than reading it from a fixed table, so a station shows up on the day it actually happens.

What sign is the Moon in on January 4, 2027?

The Moon is in Sagittarius at 7°32' Sagittarius on January 4, 2027. It leaves Sagittarius at approximately 10:00 UTC on January 6. The Moon spends between two and three days in each sign and is the fastest-moving body in a chart, which is why consecutive days differ from each other at all.

What is the Moon phase on January 4, 2027?

The Moon is a waning crescent on January 4, 2027, approximately 10 per cent illuminated, at an elongation of 323.65 degrees from the Sun. The phase is derived from the angle between the Sun and the Moon rather than looked up, so it is consistent with every other figure on this page.

Where is the Sun on January 4, 2027?

The Sun is in Capricorn at 13°54' Capricorn on January 4, 2027. That degree is what a sun-sign horoscope is based on, and it is one of roughly ten placements in a full birth chart.

How are these planetary positions calculated?

On MyMysticDay’s own servers, for noon UTC on the date shown. Solar and lunar positions follow the standard series published in Jean Meeus’s Astronomical Algorithms; planetary positions follow NASA JPL’s Keplerian elements with their secular rates. Nothing is requested from a third-party ephemeris service, and the method, tolerances and test values are published on the methodology page.

Why noon UTC and not midnight?

A date is a whole day and the planets move through it. Noon is the midpoint, so the positions shown are the ones true for the largest part of the day across the largest number of time zones. Midnight UTC would describe a moment most of the world has either not reached yet or already left. The Moon moves about half a degree an hour, so it is the only body for which the choice materially changes the figure.
