Locational Astrology
Cyclocartography Calculator
Compare monthly snapshots of moving planet lines near one destination. Anonymous results compute the first three checkpoints, while a free account computes up to twelve. The sampler checks the 15th of each month at 12:00 UTC and keeps natal astrocartography as separate context.
What This Cyclocartography Calculator Measures
This tool checks the moving sky's angular lines near one destination at a fixed monthly cadence. It calculates a dated astrocartography overlay on the 15th of each month at 12:00 UTC, then measures the nearest Jupiter, Saturn, Uranus, Neptune, or Pluto line.
At least two neighboring samples form a window when the same planet angle is observed within 300 miles. The result shows the observed checkpoints separately from the surrounding bounds on an unknown entry or exit time. It does not claim that the line stayed inside the band between samples.
Natal astrocartography is calculated from your birth data and shown as a separate context layer. Moving lines and the natal map remain separate in this method, and exact intersections remain outside its scope.
How This Cyclocartography Tool Differs from Canonical CCG
Jim Lewis's Cyclo*Carto*Graphy, often shortened to CCG, uses a different method. Canonical CCG combines progressed Sun, Moon, Mercury, Venus, and Mars positions with transiting Jupiter through Pluto, then reads those dynamic positions against the natal astrocartography frame.
This cyclocartography calculator currently computes dated transit angularity and presents natal astrocartography beside it as separate context. Its procedure name is sampled-transit-locality-v1. Read its output as monthly transit locality samples rather than a canonical CCG calculation.
How the Monthly Sampling Works
| Part | Method | What the result supports |
|---|---|---|
| Monthly timeline | Up to twelve snapshots on the 15th at 12:00 UTC, with three in the anonymous preview | Comparing slow planet proximity by month |
| Timeline bodies | Jupiter, Saturn, Uranus, Neptune, and Pluto | Planning scale signals from slower moving lines |
| Distance bands | Strong below 150 miles, included through 300 miles | A consistent comparison across destinations |
| Today panel | All ten listed planets at 12:00 UTC | One current date snapshot inside a 500 mile search radius |
| Natal panel | Birth moment astrocartography, calculated separately | Nearby natal line context for the chosen place |
Reading a Sampled Window
Each dot records the closest angular line for one slow planet at one monthly checkpoint. The planet supplies the theme, while MC, IC, ASC, or DSC identifies the area of life emphasized in the location reading.
A window requires at least two consecutive monthly samples where the same angle is observed inside the 300 mile band. Its closest approach comes directly from the nearest sampled value. Surrounding samples only bound an unknown entry or exit time. Retrograde turns and contacts between the monthly dates require a finer timing calculation.
The natal panel answers a separate question: which birth chart lines already run near the destination? Nearby natal lines can inform the reading. Exact dynamic to natal line intersection calculations remain outside this method.
Using the Sampler for Planning
Run the same date range for each city on a shortlist and compare the distances. Treat the results as one planning input alongside work, housing, cost, health, and the people involved.
Start with the astrocartography calculator to inspect natal lines. Use the relocation chart calculator when you need the houses and angles recast for a destination.
A transit chart covers contacts to the birth chart without a geography layer. Local space astrology covers compass directions from a chosen origin.

Frequently Asked Questions
What does this cyclocartography calculator calculate?
It calculates up to twelve dated moving sky angularity maps, one on the 15th of each month at 12:00 UTC. The anonymous preview computes the first three checkpoints. For one destination, it measures the nearest Jupiter, Saturn, Uranus, Neptune, and Pluto angular lines. At least two consecutive monthly samples inside 300 miles are required for a sampled window.
Is this a canonical Cyclo*Carto*Graphy calculation?
No. Canonical CCG combines progressed Sun, Moon, Mercury, Venus, and Mars positions with transiting Jupiter through Pluto against the natal astrocartography frame. This tool uses the sampled-transit-locality-v1 procedure: dated transit angularity with natal astrocartography shown as a separate context layer.
How are the monthly sample dates chosen?
The sampler starts with the current UTC calendar month and can check the 15th of up to twelve consecutive months. Anonymous results compute the first three checkpoints. Each dated transit overlay uses 12:00 UTC. The result also includes a separate snapshot for the current date at 12:00 UTC.
Does the sampler find exact contact dates?
The sampler reports monthly checkpoints. A grouped window requires the same planet angle within 300 miles on at least two consecutive samples. The observed checkpoint range remains separate from the bounds on an unknown entry or exit time. Exact entry, peak, exit, station, and retrograde pass dates require a finer solver between those checkpoints.
Which planets appear in the timeline?
The monthly timeline checks Jupiter, Saturn, Uranus, Neptune, and Pluto. The separate current date snapshot checks the Sun through Pluto at 12:00 UTC. Faster bodies are omitted from the monthly timeline because one monthly checkpoint cannot represent their shorter contacts.
How close does a line need to be?
A monthly sample is Strong below 150 miles. Samples from 150 through 300 miles are Moderate. The current date and natal context panels search within 500 miles, then the current date panel shows the two nearest lines when none fall inside that radius.
Why does the form require an exact birth time?
The moving transit lines are dated sky positions, but the natal astrocartography panel depends on your birth angles. Those angles change quickly with clock time. The exact time requirement keeps the separate natal context from being presented with false precision.
How should I use the sampled windows?
Use them to compare planning periods or shortlist cities at monthly resolution. Read the planet and angle as an astrological pattern, then keep the measured distance and sample date visible. Jobs, housing, health, cost, and the people involved carry more authority in a travel or relocation decision.
