A Lunar Return Chart Shows The Tone Of One Moon Cycle

A lunar return chart is a short-range timing chart. It begins when the Moon returns to the same zodiac position it held at birth and describes the emotional weather of the next lunar month. It is especially useful when you want a focused view of mood, pace, routines, relationship needs, and the house topics that become more immediate.

Why Lunar Returns Work Best As Monthly Context

The lunar return should not replace transits or the natal chart. It works best as a monthly container. The return Moon, Ascendant, angular planets, and close contacts to natal placements show which themes are louder for this cycle. If a transit is already activating the same house or planet, the lunar return can show how that bigger story feels in daily life.

How To Read The Result Without Chasing Every Detail

Start with the lunar return Moon, the Ascendant, the Moon house, and tight aspects back to natal planets. Then look for repetition. If the Moon, angles, and natal contacts keep pointing to the same topic, that is the monthly theme to prioritize. A useful lunar return reading is compact, not encyclopedic.

Calculation standards

How this Regu calculation works

The method, input sensitivity and limits below reflect the active calculation contract rather than a generic description of the technique.

Exact calculation
Regu finds the moment in the selected month when the transiting Moon returns to its natal zodiac longitude, then casts a chart for that moment at the chosen return location. Houses use the selected Placidus or Whole Sign system.
Required inputs and precision
Birth date, local birth time and place, target month, return location and house system. Birth time refines the natal Moon; return location changes angles and houses.
Non-personal example
If the natal Moon is at 12°34′ Taurus, the return is the instant the transiting Moon again reaches that longitude. Moving the return city does not change the return instant, but can change the Ascendant and houses.
What the result contains
Exact return moment, wheel, planets, houses, aspects inside the return chart and contacts back to the natal chart.
What it does not claim
The chart describes a short symbolic cycle, not a guaranteed monthly outcome. With uncertain birth time, the return moment, angles and house emphasis should be treated as provisional.
