An eclipse happens when the Sun, Moon and Earth line up closely enough that one body blocks the light reaching another. In astrology, eclipses are read as turning points: stronger versions of new and full moons that tend to mark endings, beginnings and changes of direction. They arrive in clusters called eclipse seasons, roughly every six months. Where an eclipse lands in your own chart suggests which area of life may be in transition.
A solar eclipse happens at a new moon. The Moon passes between the Earth and the Sun and blocks some or all of the Sun's light. It can be total, partial or annular. An annular eclipse leaves a bright ring because the Moon is a little too far from Earth to cover the Sun completely.
A lunar eclipse happens at a full moon. The Earth sits between the Sun and the Moon, and the Earth's shadow falls on the Moon. During a total lunar eclipse the Moon often turns a deep red.
A solar eclipse is only seen along a narrow path on the ground. A lunar eclipse can be seen from anywhere on Earth where the Moon is up at the time.
There is a new moon and a full moon every month, so why not an eclipse every month? The answer is a small tilt.
The Moon's orbit is tilted about 5 degrees against the path the Sun appears to follow. Most months, the Moon passes a little above or below the line between Earth and Sun, and no shadow lands.
The two places where the Moon's path crosses the Sun's path are called the lunar nodes. An eclipse can only happen when a new or full moon falls near one of these nodes.
The Sun lines up with the nodes about every 173 days, a little under six months. Each of those windows is called an eclipse season and lasts around five weeks.
Every eclipse season brings at least two eclipses, one solar and one lunar, about two weeks apart. Sometimes it brings three. That adds up to between four and seven eclipses a year.
The nodes drift slowly backward through the zodiac, taking about 18.6 years to go all the way around. Because of this, eclipses tend to fall in the same pair of opposite signs for about a year and a half before moving on, for example Aries and Libra.
In older traditions, eclipses were seen as omens, mostly for kings and nations. Modern astrology reads them in personal terms, as moments when the pace of change picks up.
The usual associations follow the two kinds of eclipse:
Many astrologers also say the effects of an eclipse unfold over the following months, not on the day itself. The day is more like a marker than an event.
Every eclipse happens at a specific degree of a sign. To read it personally, you find where that degree falls in your birth chart.
First, look at the house. Say a solar eclipse lands at 15 degrees of Leo, and that degree falls in your tenth house, the house of career and public life. The traditional reading is that a new chapter in your work or reputation may open over the following months.
Then look for close contacts. If the eclipse lands within a few degrees of a planet or point in your chart, such as your Sun, Moon or rising sign, it is usually read as more personal. An eclipse right on your natal Moon might be read as a season of change around home, family or emotional needs.
It also helps to follow the whole series. Because eclipses stay in one pair of signs for about eighteen months, they keep returning to the same two houses in your chart. Looking at that pair of houses together often tells a fuller story than any single eclipse.
If an eclipse touches nothing in particular, it may pass quietly for you. Most eclipses do.
Eclipses have a dramatic reputation, and it is easy to feel nervous about them. It helps to remember how common they are. Four or more happen every year, and everyone lives through dozens of them.
A useful way to hold an eclipse is as a window, not a verdict. It points to an area of life that may be ready to shift. What happens there still depends on your choices and circumstances.
Some people like to avoid starting big commitments right on an eclipse day and wait a few days for things to settle. That is a personal preference, not a rule. Nothing bad is expected to happen if you do go ahead.
When an eclipse season comes up, look at the eclipse degrees and find the houses they fall in for you. Journaling around that area for a few weeks can be a simple way to notice what is changing.
If you want to watch one, a lunar eclipse is safe to view with the naked eye. A solar eclipse is not. Only look at the Sun through certified eclipse glasses or a proper solar filter.
To see which houses and planets an eclipse might touch, start by looking at your own birth chart. You will need a birth time to read houses.
A solar eclipse happens at a new moon, when the Moon blocks the Sun. A lunar eclipse happens at a full moon, when the Earth's shadow falls on the Moon. Astrology links solar eclipses with beginnings and lunar eclipses with endings.
Between four and seven. They come in eclipse seasons roughly every six months, with two or sometimes three eclipses in each season.
Older traditions treated them as ominous, but modern astrology reads them as turning points. They mark areas of life that may be changing, and most eclipses pass without anything dramatic for most people.
Find the degree and sign of the eclipse, then see which house it falls in and whether it lands within a few degrees of a planet or angle in your birth chart. Close contacts are read as more personal.
