What is cazimi in astrology?
Cazimi is a traditional term for a planet extremely close to the Sun. This calculator uses the strict 17-arcminute threshold for cazimi, then separates the broader 1-degree heart-of-Sun band and the 17-degree under-the-beams band. Many traditional authors read the tight condition as fortifying, but the meaning still depends on the planet, chart context, and interpretive tradition.
Cazimi vs combust vs under the beams
| Condition | Orb from Sun | Effect on the planet | Approximate frequency |
|---|---|---|---|
| Cazimi | within 17 arcminutes (~0.28 degrees) | traditionally treated as fortified | brief |
| Heart of the Sun | within 1 degree | adjacent strengthening band in some sources | brief |
| Combust | often ~8.5 degrees, with variants by source | traditionally read as hidden or weakened | common |
| Under the beams | often 15 to 17 degrees, depending on source | visibility is obscured | common |
This Cazimi calculator only labels cazimi, the broader 1-degree heart-of-Sun band, under the beams through 17 degrees, and clear. Use the Combust Planets calculator for planet-specific combustion rules.
Example: how the math works
Suppose the Sun sits at 15 degrees 00 arcminutes Aries and Mercury at 15 degrees 10 arcminutes Aries. The angular separation is 10 arcminutes, which falls inside the 17-arcminute cazimi orb. Mercury is therefore cazimi. If Mercury were instead at 15 degrees 30 arcminutes Aries, the orb would be 30 arcminutes: outside cazimi, inside the heart of the Sun (1 degree band), and well inside the under-the-beams range. The calculator above runs this comparison for every body in your chart.
How rare is cazimi?
Cazimi frequency tracks the synodic cycle of each body with the Sun, so the cazimi window is brief for every body. Inner-planet cazimis happen several times per year, while the slower planets usually have one Sun conjunction per year from a geocentric perspective. The Calendar tab shows detected upcoming dates from the current and following calendar year. For per-body dates, see the planet pages linked below.
Sources and methodology
Public reference works define cazimi as a very close Sun conjunction, most often within 17 arcminutes of the Sun's longitude, though some sources preserve wider heart-of-Sun usage. This page keeps those thresholds separate: cazimi means 17 arcminutes or less, heart of the Sun means more than 17 arcminutes through 1 degree, and under the beams means more than 1 degree through 17 degrees.
Under-the-beams limits vary by author. This calculator uses 17 degrees because that is the local threshold shared with Augurine's combustion and solar-condition code, while noting that many historical texts use 15 degrees or another nearby value.
Natal positions come from Augurine's chart API. The calendar endpoint samples each supported body once per day at noon UTC, detects dates when the body is within 17 arcminutes of the Sun, and reports the closest daily sample for that window. It is a date-level event feed, not an exact start-time or peak-time electional calendar. If you are choosing a start window, pair the cazimi date with the void-of-course Moon calendar before treating it as usable electional timing.

Cazimi in Vedic astrology
This calculator is built for a Hellenistic and modern tropical workflow. Classical Jyotish handles planets close to the Sun through combustion (asta) with its own orbs and interpretive rules. If you practice Vedic astrology, treat this page as a solar-proximity reference rather than a Jyotish condition calculator, and use the sidereal chart calculator for Lahiri positions when you need them.

Frequently Asked Questions
What is cazimi in astrology?
Cazimi describes a planet extremely close to the Sun. This calculator uses the strict 17-arcminute threshold for cazimi, while showing a separate broader heart-of-Sun band through 1 degree. Many traditional authors read the tight condition as fortifying, but the rest of the chart still matters.
What is the difference between cazimi and combust?
Both describe a planet near the Sun, but the orbs and meanings differ. Cazimi means within 17 arcminutes and is often read as fortifying. Combustion is the wider hidden or weakened condition close to the Sun. Under the beams, which this calculator marks through 17 degrees, is the broader visibility band around both.
How do I know if a planet is cazimi in my birth chart?
Take the longitude of the planet, take the longitude of the Sun, and compute the smaller of the two angular distances between them. If the result is less than 17 arcminutes (about 0.28 degrees), the planet is cazimi. This calculator does the math for every body in your chart and classifies each into cazimi, heart of the Sun, under the beams, or clear.
How often does cazimi happen?
It follows each planet's Sun conjunction cycle. Mercury has several cazimis per year. Venus has inferior and superior conjunction cazimis across its synodic cycle. Mars has one Sun conjunction roughly every two years. Jupiter, Saturn, Uranus, Neptune, Pluto, and Chiron usually have one geocentric Sun conjunction per year, with the sign and degree drifting at each body's own pace.
Can the Moon be cazimi?
This calculator does not classify the Moon as cazimi. A new moon is the Sun-Moon conjunction, but lunations have their own timing and interpretation rules, so this tool keeps them out of the cazimi event feed.
What does it mean when a planet is in the heart of the Sun?
Some traditional sources use a broader heart-of-Sun range than the later strict 17-arcminute cazimi threshold. We display 17 arcminutes through 1 degree as a separate tier so you can see when a planet is close to the Sun without treating it as strict cazimi.
Is cazimi good or bad for malefics like Mars and Saturn?
Traditional astrology often treats cazimi as fortifying regardless of whether the planet is a benefic or malefic, but Mars remains Mars and Saturn remains Saturn. Read the condition alongside sect, dignity, house placement, aspects, and the chart topic you are judging.
How accurate is this cazimi calculator?
Natal solar-proximity orbs are computed from the chart positions returned by Augurine's chart API. The calendar endpoint samples supported bodies once per day at noon UTC and reports the closest daily sample within each detected 17-arcminute window, so it is useful for date-level tracking, not exact start or peak times.
Where can I see when the next cazimi happens?
Switch to the Calendar tab on this page. It shows detected upcoming cazimi dates from the current and following calendar year, sorted by date, with sign, degree, and the closest daily-sample orb.
Is cazimi used in Vedic astrology?
This calculator is built for a Hellenistic and modern tropical workflow. Classical Jyotish handles planets close to the Sun through combustion (asta) with its own orbs and interpretive rules, so treat this page as a solar-proximity reference rather than a Jyotish condition calculator.
