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.

Explain it like I'm 12

The Moon rises later through much of the month because it moves around Earth while Earth rotates. This calculator asks the astronomy engine for the actual rise and set instants for your entered place.

Why people use this calculator

  • Check moonrise and moonset for an observing date.
  • Teach why moonrise shifts later through the lunar month.
  • Compare phase age with local rise and set timing.

Common mistakes

  • Forgetting that a date can have no moonrise or no moonset at some locations.
  • Forgetting that latitude and horizon height matter.
  • Using the wrong UTC offset during daylight saving.

Citation sentence

CalculationTime calculates moonrise and moonset with Astronomy Engine SearchRiseSet(Moon) for the entered observer location and date.

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).

Worked example

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.

Professional note

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

Regional and unit assumptions

Standard or basis: Astronomy Engine rise/set search with manual UTC-offset display. This is not an IANA timezone database, airline schedule, legal deadline or safety-critical almanac.

Assumptions and limitations

Methodology & Accuracy

How this calculator is checked

CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

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).

Standard or basis

Standard or basis: Astronomy Engine rise/set search with manual UTC-offset display. This is not an IANA timezone database, airline schedule, legal deadline or safety-critical almanac.

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.

Master's Tip

Questions

Is this an official moonrise table?

It uses Astronomy Engine for the rise/set search, but official local services can still differ for terrain, horizon and safety-critical contexts.

Why does moonrise move later each day?

The Moon advances in its orbit each day, so Earth has to rotate a little farther before the Moon rises again.

Why can official moonrise differ?

Latitude, longitude, elevation, horizon height, refraction and parallax all affect the real local rise time.

Calculation note

Moonrise is a harder problem than moon phase because it depends on local observing geometry. The engine-backed page now searches the Moon's local rise and set instants directly for the entered observer.
