Formula used

observer = Astronomy.Observer(latitude, longitude, elevationMetres). t0 = local civil midnight converted to UTC. Moonrise = SearchRiseSet(Moon, observer, +1, t0, 1.05). Moonset = SearchRiseSet(Moon, observer, -1, t0, 1.05). Lunar phase context = MoonPhase(t0).

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Astronomy Engine rise/set result with manual UTC-offset display. Official local moonrise/moonset can differ when horizon or legal definitions matter.

  • Astronomy Engine computes the Moon rise/set instants for the entered observer.
  • Timezone offset is entered manually and does not apply daylight-saving rules automatically.
  • Flat horizon and entered elevation are used; local terrain, weather and horizon obstruction can affect visibility.
  • Some local dates may have no moonrise or no moonset in the search window; the calculator reports that explicitly.

Master’s Tip

How to use the result well

Master’s Tip: moonrise is more location-sensitive than phase. Check latitude, longitude, elevation and UTC offset before comparing nights.

Method

observer = Astronomy.Observer(latitude, longitude, elevationMetres). t0 = local civil midnight converted to UTC. Moonrise = SearchRiseSet(Moon, observer, +1, t0, 1.05). Moonset = SearchRiseSet(Moon, observer, -1, t0, 1.05). Lunar phase context = MoonPhase(t0).

  1. For 16 July 2026 near Sydney, the calculator converts the local civil date to UTC, searches for Moon rise and set from the entered latitude and longitude, then displays the UTC and local civil times.

Assumptions

  • Astronomy Engine computes the Moon rise/set instants for the entered observer.
  • Timezone offset is entered manually and does not apply daylight-saving rules automatically.
  • Flat horizon and entered elevation are used; local terrain, weather and horizon obstruction can affect visibility.
  • Some local dates may have no moonrise or no moonset in the search window; the calculator reports that explicitly.

Method

The calendar searches Moon rise and set instants for the entered observer

The route converts the local date into a UTC search window, calls Astronomy Engine SearchRiseSet for the Moon, and adds engine-derived phase context at local midnight.

Formula

observer = Astronomy.Observer(latitude, longitude, elevationMetres). t0 = local civil midnight converted to UTC. Moonrise = SearchRiseSet(Moon, observer, +1, t0, 1.05). Moonset = SearchRiseSet(Moon, observer, -1, t0, 1.05). Lunar phase context = MoonPhase(t0).

Assumptions

Astronomy Engine computes the Moon rise/set instants for the entered observer. Timezone offset is entered manually and does not apply daylight-saving rules automatically. Flat horizon and entered elevation are used; local terrain, weather and horizon obstruction can affect visibility. Some local dates may have no moonrise or no moonset in the search window; the calculator reports that explicitly.

Trust boundary

Moonrise and moonset can be missing or shifted near edge cases, and local terrain/horizon details matter. This is a planning calendar, not an official observatory or navigation almanac.
