Understanding moon phases
The Moon completes one full cycle, new to new, every 29.53 days (the synodic month). This cycle divides into eight phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent. The four primary phases, New Moon, First Quarter, Full Moon, and Last Quarter, center on the exact Sun-Moon angles of 0°, 90°, 180°, and 270°. The four intermediate phases fill the spans between them.
Alongside the phase, the Moon's zodiac sign shifts roughly every 2 to 2.5 days, adding a second layer of meaning. In the horary tradition, astrologers also track the void-of-course Moon, a window after the Moon's last major aspect before it changes sign, traditionally considered unfavorable for starting new ventures. For finer electional timing inside the day, compare this lunar context with the electional astrology calculator and planetary hours for today. This tracker shows the current phase, illumination, Moon sign, and degree from ephemeris-backed sky data, refreshed hourly.
How astrologers use moon phases for daily timing
Many astrologers time activities around the lunar cycle. New Moons are commonly used for intention setting, while the waxing phases (Waxing Crescent through Waxing Gibbous) are read as a period of building light before the Full Moon. Waning phases (Waning Gibbous through Waning Crescent) are usually treated as better suited to review, integration, and preparation for the next cycle.
The Moon sign adds texture. A Moon in earthy Taurus is often read as grounding and practical; a Moon in airy Gemini is read through curiosity and communication; a Moon in watery Scorpio is often read as more private and intense. Combining phase condition with sign condition gives you a symbolic daily compass, not a guarantee of how the day will unfold.
In modern astrology, Dane Rudhyar popularized a separate natal lunation-type framework that divides the Sun-Moon cycle into eight equal 45-degree stages. That framework can add another symbolic layer to your Moon sign, but it should be read as an interpretive model rather than a fixed personality test.

Frequently Asked Questions
What moon phase is it today?
This page shows the current lunar phase, illumination percentage, Moon sign, degree, and phase angle. The page is refreshed hourly from ephemeris-backed sky data.
How often is the moon phase data updated?
Moon phase data is refreshed hourly from Augurine's ephemeris-backed sky data. Illumination percentage, lunar sign, and degree are computed from current Sun and Moon positions rather than pulled from a static interpretation table.
What are the 8 moon phases?
The 8 phases are New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent. This tracker labels New Moon within 6 degrees of conjunction, First and Last Quarter within 6 degrees of the square, and Full Moon within 6 degrees of opposition. The waxing and waning crescent and gibbous phases fill the intervals between those primary phase windows. Some natal lunation systems instead use equal 45-degree phase types.
How does the moon sign affect emotions?
In astrology, the transiting Moon sign is read as a short-lived symbolic atmosphere. Moon in Cancer is often interpreted through sensitivity and caretaking, while Moon in Aries is read through speed and directness. Your natal chart matters too, especially when the transiting Moon contacts your own Moon or other natal placements.
What's the difference between moon phase and moon sign?
Moon phase describes the Sun-Moon angle and how much of the Moon is illuminated from our perspective. Moon sign is the 30-degree zodiac sign the Moon currently occupies in the chart calculation. Both change on different cycles: the phase cycle is about 29.5 days, while the Moon changes signs roughly every 2 to 2.5 days.
