Breaking out of a very negative situation to a more positive space with many options
This Saros Series concerns itself with breaking out of a very negative situation where no hope can be seen to a more positive space containing many options. A worry that may have been affecting a person will suddenly clear. The solution is shown by the Cosmos and needs to be taken up without too much delay.
Birth Aspects
Mars is on the midpoint of the New Moon/Pluto, and the New Moon is on the midpoint of Mercury/Uranus. In addition to this, Mercury is on the Mars/Saturn midpoint.
Sudden changes in group associations through travel or ideas, with positive outcomes
Under the influence of this family of eclipses, individuals may suddenly change the groups with which they are mixing, either through travel or ideas. However, the separation implied by the Venus-Saturn would produce very positive outcomes. This whole eclipse Series could also talk of suddenly deciding to make greater commitments in a relationship. Either way, the eclipse is gentle and individuals can trust the situations that arise and allow themselves to be led along by their momentum.
Birth Aspects
The New Moon is on the Uranus/Node midpoint, and Jupiter is on the midpoint of Venus/Saturn.
Need to make sudden reforms as old ideas or methods fail
This family of eclipses is concerned with the need to make sudden reforms. Old ideas or methods will fail and new systems are required to deal with the events brought by the eclipse. As a consequence, the person will need to think of new ways of handling the issues. Any blocks could be violently or tragically removed.
Birth Aspects
There is a Mars-Pluto conjunction, and Uranus is on the midpoint of Mercury/Venus.
Opportunities to accept greater responsibilities that come suddenly
Opportunities to accept greater responsibilities can come suddenly into the person's life. These new commitments will most likely come as a result of another individual being unable to carry on. Although the events that herald these opportunities may be difficult, the outcomes in terms of harmony or self-esteem are good.
Birth Aspects
Saturn is forming a sextile to the New Moon, and Venus is conjunct the Node. The New Moon is also on the midpoint of Mars/Saturn and Mercury/Pluto.
Successful outcomes to long-term worries or illness
This Saros Series will bring successful outcomes to long-term worries or illness. An issue that has worried or drained the individual for some time will at first seem worse and then clear, with successful outcomes.
Birth Aspects
Jupiter is on the midpoint of the New Moon/Mars, and Neptune is on the New Moon/Saturn midpoint.
Large, ambitious group projects requiring separation or breaking of an existing bond
This is an eclipse family of groups and associations. Its energy is about large, ambitious group projects. These group projects will require a separation or the breaking of a bond that already exists. The individual may well experience this eclipse initially as a separation and then as joint achievement.
Birth Aspects
There is a New Moon-Venus conjunction and, in addition, the Node is on the midpoint of the New Moon/Mars. Pluto is also on the midpoint of Mars/Node.
Confusion in personal relationships, unexpected financial happenings, and possible illness
A most peculiar eclipse family, heralding an acute time of confusion in personal relationships, unexpected happenings in financial matters, and possible illness. Unrequited love, despair, confusion, a draining of energy, a peculiar turn of events. No important decisions should be made concerning incoming events, as there is too much confusion and possible delusion to make clear judgments.
Birth Aspects
Neptune is forming an opposition to Saturn, and Venus is on the Uranus/Neptune midpoint.
Expansive energy with underlying frustration, inhibitions, and separation
This family of eclipses has a very similar energy to its North Node cousin: expansive energy under which lies a more sinister flavor. An urge to expand is experienced, but the expansion contains frustration, inhibitions, and loss or separation. Australia's chart seems to be very sensitive to this 13 Series. The first time it affected Australia's chart was 13 South in 1939, the year when Australia went to war. It occurred again in 1975, and that was a year of constitutional crises climaxing in the dismissal of Prime Minister Whitlam. The three times that 13 North affected Australia's chart were: first in 1938, The Empire Games in Sydney; second in 1956, The Olympic Games in Melbourne; and third in 1974, Cyclone Tracy. Darwin, the only city in Australia to be bombed in WW2, was devastated by a cyclone. This event caused the biggest peacetime evacuation that Australia had ever seen. Australia seems to be experiencing this family of eclipses as a striving for group endeavors, in a positive or negative fashion.
Birth Aspects
There is a Jupiter-New Moon conjunction, and Mars is on the midpoint of the New Moon/Saturn.
Joy through commitment, with good news entailing responsibilities
There is a sense of joy through commitment about this Saros Series. When this family affects a chart, it is a time of good news that entails responsibilities or commitments, but ones in which there is joy in the undertaking. Pregnancy, birth, parenthood are just some of this eclipse family's possible expressions.
Birth Aspects
The New Moon is conjunct Mercury, while Venus is on the Mars/Jupiter midpoint. There is also a trine between the Node in Cancer and Saturn in Scorpio.
Success after long periods of hard work, with an obsessive idea finally accepted
This eclipse family will tend to bring success. There may have been long periods of hard work from which the success has grown. With the Mercury-Pluto content, there is also the potential for an obsessive idea to finally be accepted, which then leads to the promised success of the Jupiter. During this eclipse period, individuals should push for the acceptance of their ideas or methodologies, as this eclipse can bring the long-awaited breakthrough.
Birth Aspects
Jupiter is on the midpoint of New Moon/Pluto as the New Moon is on the midpoint of firstly Mercury/Pluto and secondly Mars/Saturn.

What is a Saros cycle?
A Saros cycle is a period of approximately 6,585.3 days (18 years, 11 days, and 8 hours) after which the Sun, Moon, and lunar nodes return to nearly identical relative positions. This means eclipses repeat in predictable families: each eclipse in a Saros series occurs about 18 years after the previous one in the same family, shifted roughly 120 degrees westward on the globe. The Babylonians discovered this periodicity over 2,500 years ago, and it remains the most reliable framework for understanding eclipse patterns in both astronomy and astrology.
Each Saros series begins with a small partial eclipse near one of Earth's poles, gradually produces more dramatic total or annular eclipses near the equator at its peak, and eventually ends with partial eclipses near the opposite pole. A complete series spans 1,200 to 1,500 years and produces 70 to 85 eclipses. The 40 currently active solar eclipse series were cataloged and astrologically delineated by Bernadette Brady in her work Predictive Astrology: The Eagle and the Lark. For a deeper exploration of each series, visit our complete Saros cycle guide.
Saros cycles in astrology
In astrological practice, each Saros series carries a unique thematic signature derived from the planetary aspects present at the moment of its birth (the series' very first eclipse). When a solar eclipse from a given Saros series falls near a sensitive point in your natal chart, you experience that series' themes playing out in the houses and areas of life that the eclipse activates. Understanding which Saros series is active during any given eclipse season gives you a far more precise read than simply noting that "an eclipse happened."
For example, a 6 South eclipse carries themes of being forcefully separated from a union or partnership, while a 19 North eclipse brings sudden realism through news that transforms an emotional situation. Knowing the series helps you anticipate the flavor of the eclipse before it arrives. You can explore each of the 40 active Saros series to understand their birth charts and delineations.
How eclipses connect to Saros families
Every solar eclipse belongs to exactly one Saros series. When you look up an eclipse by date in this calculator, the tool identifies its Saros family and shows you the theme that family carries. Because eclipses in the same Saros series recur every 18 years, you can trace thematic threads across your life: the eclipses of 1999, 2017, and 2035 all belong to 1 North, for instance, carrying the same underlying pattern of unexpected events involving groups that pressure personal relationships.
Lunar eclipses have their own Saros numbering (tracked by NASA) but have not received the same individual delineation treatment in the astrological literature. This calculator includes both solar and lunar eclipses in its timeline for completeness, and provides sign-based interpretations for lunar eclipses as a meaningful fallback. For the most precise eclipse work, focus on the Saros series themes of solar eclipses and track lunar phases through our dedicated moon phase tool.

Frequently Asked Questions
What is a Saros cycle?
A Saros cycle is an eclipse period of approximately 6,585.3 days (18 years, 11 days, and 8 hours) after which the Sun, Moon, and lunar nodes return to nearly the same relative positions. Each Saros cycle produces a 'family' of eclipses that share similar characteristics and astrological themes. The cycle was known to ancient Babylonian astronomers and remains one of the most reliable eclipse prediction tools in both astronomy and astrology.
How many active Saros series are there?
There are approximately 40 active solar eclipse Saros series producing eclipses in the current era. Each series was cataloged by Bernadette Brady, who assigned names like '1 North' or '6 South' based on their birth charts. A Saros series is considered active as long as it is still producing eclipses; each series lasts roughly 1,200 to 1,500 years from its first partial eclipse to its last.
What does a Saros series mean in astrology?
In astrology, each Saros series carries a distinct theme derived from the planetary picture at the moment of its first eclipse (the series 'birth chart'). When an eclipse from a particular Saros series activates your natal chart, you experience that series' themes. For example, 1 North brings unexpected events involving groups that pressure personal relationships, while 6 South carries themes of being forcefully separated from a union.
How long does a Saros series last?
A typical Saros series lasts between 1,200 and 1,500 years and produces around 70 to 85 eclipses over its lifetime. It begins with small partial eclipses near one of the poles, gradually produces total or annular eclipses near the equator at its peak, then ends with small partial eclipses near the opposite pole. Each successive eclipse in the series shifts about 120 degrees westward in longitude and roughly 8 hours later in the day.
Do solar and lunar eclipses share Saros series?
Solar and lunar eclipses have separate Saros numbering systems. The 40 named series (1 North through 19 South, plus additional families) tracked by Bernadette Brady refer specifically to solar eclipses. Lunar eclipses have their own Saros series with NASA catalog numbers, but they have not received the same astrological delineation treatment. This calculator tracks both solar and lunar eclipses in the timeline but provides series theme interpretations only for solar eclipses.
How is this different from a regular eclipse calendar?
A regular eclipse calendar shows dates, types, and visibility paths. This calculator goes further by linking each solar eclipse to its Saros family and providing the astrological delineation for that family. You can see not just when the next eclipse occurs, but what themes it carries, which birth aspects define its series, and how it connects to the broader 18-year pattern. The reference section lets you explore all 40 active series and their upcoming eclipses.
