Zodiac TimelineWhat is a void-of-course Moon?
The Moon spends about two and a half days in each zodiac sign. While it is in a sign, it forms aspects with the Sun and the planets, and astrology reads each aspect as a connection that gets things moving. An aspect is an exact angle between two bodies as seen from Earth: 0° for a conjunction, 60° for a sextile, 90° for a square, 120° for a trine and 180° for an opposition.
At some point the Moon makes its last aspect in that sign. From that moment until it enters the next sign, it is void of course. It is still in the same sign; it simply makes no more aspects there. When it enters the next sign, it starts making aspects again and the void period is over.
For example, this week: the Moon makes its last aspect in Leo, a conjunction with Jupiter, at . From then until it enters Virgo at , the Moon is still in Leo but void of course.
How often it happens
The Moon moves through a sign in about two and a half days, and it goes void of course before almost every sign change. A period can last a few minutes or close to two days. The times above show this week’s periods in your local time, so you can see at a glance when the next pause begins and ends.
What it means in astrology
Tradition says that what starts while the Moon is void of course tends to go nowhere, or turns out differently than planned. Many astrologers use these hours for routine tasks, rest, reflection and wrapping things up, and wait for the Moon to enter its next sign before launching something new. It is a timing tool, not a warning: nothing bad is expected to happen, the moment is simply better for finishing than for beginning.
How we calculate it
The Moon’s position and every aspect are computed from NASA JPL’s DE440 ephemeris. A void-of-course period starts at the moment of the Moon’s last exact major aspect to the Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune or Pluto in its current sign, and ends at the moment it enters the next sign. If the Moon makes no such aspect in a sign, it is void of course for its whole stay there.
Frequently asked questions
- How long does a void-of-course Moon last?
- Anywhere from a few minutes to nearly two days. Most periods last several hours; in 2026 the typical one runs about eight hours.
- How often is the Moon void of course?
- Almost every time it changes sign, which happens about every two and a half days. In 2026 the Moon goes void of course before each of its 160 sign changes.
- What should I do during a void-of-course Moon?
- Tradition favors routine work, rest, reflection and finishing what is already under way, and advises waiting to launch something new until the Moon enters its next sign. Use the times on this page to plan around it.
- Why do void-of-course times differ between sites?
- Some sites count only the traditional planets, the Sun through Saturn, which can start a period earlier; this page uses the modern convention that counts the Sun through Pluto, as most astrology calendars do. Sites also differ in the time zone they print; here every time is in your own local time.
