In September 2027, this calculation finds 4 primary Moon phases, 19 planetary sign changes or stations, and 88 exact major aspects among the Sun, Moon, and planets. Every timestamp below is in UTC. The Moon moves quickly, so a local civil date may differ from the UTC date shown here.
Compare the same month’s void-of-course Moon intervals. That table combines the last qualifying exact lunar aspect with the next tropical sign ingress under its stated method.

Calculation method
All event times are UTC and rounded to the nearest minute. The local Astronomy Engine calculates apparent geocentric tropical ecliptic longitudes. A sign change is a crossing of a 30° boundary; a station is a reversal of apparent longitude motion. Moon phases are exact 0°, 90°, 180°, and 270° Sun–Moon separations. Major aspects are exact conjunctions, sextiles, squares, trines, and oppositions between moving bodies. The displayed calendar uses an inclusive UTC month and excludes its next-month boundary.
The tables describe sky geometry, not individual outcomes or local visibility. A visitor’s location and natal chart are not inputs. Use the dedicated calculators to select other date spans or bodies. Methods and limitations are detailed in the Astronomy Engine documentation.
