The exact sky of a meaningful Las Vegas moment, calculated before you buy

A place is not a decorative caption on a star map. For a memory in Las Vegas, the selected coordinates, local time and timezone determine the celestial orientation. This guide starts with a free, location-aware sky and phone gyroscope; the watermark-free HD poster is an optional keepsake after you have checked the result.

Why choose Starry Memory

  • A place-driven gift — Las Vegas starts at 36.1750° N, 115.1372° W; choosing a venue or address replaces that centre point before the poster is calculated.
  • GPS · IANA reference — Exact reference: Nevada, 36.1750° N, 115.1372° W, America/Los_Angeles.
  • Free tool — The city-specific tool works free in the browser and does not create an order.
  • Transparent limits — Weather, light pollution and local obstructions are stated as limits instead of being hidden.

In Las Vegas, the keepsake begins with a real point on Earth before it becomes an image of the sky. Its verifiable starting point is GeoNames 5506956, 36.1750° N, 115.1372° W, in timezone America/Los_Angeles.

The astronomical fingerprint of Las Vegas

Las Vegas is represented by 36.1750° N, 115.1372° W, in Nevada, using the IANA zone America/Los_Angeles. This is a mid-latitude viewpoint: the relevant celestial pole stands about 36.2° above its horizon. GeoNames record 5506956 supplies the geographic reference; its population field is 641,903 and is used for catalogue selection, not presented as a live census. The source elevation is 610 metres; terrain can hide a low object even when the geometric calculation says it rises. The following pairs are approximate daylight / night duration around the 15th of each month: January: 9 h 48 / 14 h 12; February: 10 h 40 / 13 h 20; March: 11 h 44 / 12 h 16; April: 12 h 56 / 11 h 04; May: 13 h 55 / 10 h 05; June: 14 h 27 / 9 h 33; July: 14 h 14 / 9 h 46; August: 13 h 23 / 10 h 37; September: 12 h 13 / 11 h 47; October: 11 h 03 / 12 h 57; November: 10 h 02 / 13 h 58; December: 9 h 33 / 14 h 27. The longest estimated night in this model is December at 14 h 27; the shortest is June at 9 h 33. “Night” here is the complement of daylight on a flat horizon. Civil, nautical and astronomical twilight are not interchangeable, and weather is not predicted by this table.

For a gift, the comparison explains why the confirmed place matters: a Las Vegas memory should not silently become its neighbour even when both share a timezone.

Latitude-screened constellations for Las Vegas

Each entry below gives an approximate maximum altitude at meridian transit and a practical season; an asterisk means circumpolar in this simplified centroid model: Ursa Major: 70.2°, all year *; Cassiopeia: 66.2°, all year *; Draco: 61.2°, all year *; Cepheus: 56.2°, all year *; Ursa Minor: 49.2°, all year *; Lyra: 89.8°, summer; Andromeda: 88.2°, autumn; Cygnus: 86.2°, summer; Auriga: 84.2°, winter; Boötes: 83.8°, spring; Perseus: 81.2°, winter; Gemini: 75.8°, winter; Taurus: 71.8°, winter; Leo: 68.8°, spring. This is a planning guide, not a promise that every star will be visible from a bright street. Date, hour, local obstructions and light pollution still matter. The live sky tool performs the date-specific projection that a static latitude table cannot.

Eclipse dates connected to the wider United States region

20 February 2027: Penumbral lunar eclipse, 23:14 UTC; 17 August 2027: Penumbral lunar eclipse, 07:14 UTC; 12 January 2028: Partial lunar eclipse, 04:14 UTC; 26 January 2028: Annular solar eclipse, 15:08 UTC; 14 January 2029: Partial solar eclipse, 17:13 UTC; 12 June 2029: Partial solar eclipse, 04:06 UTC. This is deliberately a regional shortlist. Solar-eclipse paths are narrow, lunar eclipses require the Moon to be above the local horizon, and both can be lost to cloud. Open the NASA source attached to each event before planning travel or observation; never look at the Sun without certified eclipse viewers.

What the calculation does — and does not claim

Coordinates, date and local time feed the same astronomical workflow used by the poster. The HYG catalogue provides star entries, while Astronomy Engine calculates moving bodies. The page does not claim that city-centre coordinates equal a hospital, venue or home: selecting an autocomplete suggestion replaces the shortcut with that location. It also separates astronomical geometry from weather and light pollution, so a correct map never becomes a claim that the ground-level sky was cloudless.

Free gyroscope first, optional poster second

On a compatible phone, the gyroscope turns the calculated sky into a movable window: tilt and rotate to explore, with star names shown beside key points. That experience is free. If a date deserves a keepsake, the same place can continue into the editor. The protected preview remains watermarked before payment; the €3.99 purchase unlocks the 4960 × 7016 px, 300 DPI file. Physical formats appear only when availability, delivery supplement and timing can be checked for the destination. Checkout is in euros; the card issuer shows the current conversion to US dollars (USD).

Frequently asked questions

What makes a Las Vegas star map personal?

The confirmed date, local time and coordinates determine the map. The city shortcut is 36.1750° N, 115.1372° W, but an exact selected venue can replace it.

Can I replace the centre of Las Vegas with an exact address?

Yes. Choose the intended autocomplete suggestion; its coordinates replace the city shortcut. Unselected free text is never silently sent to a default city.

Is the Las Vegas tool free?

Yes. The local calculation, tables and gyroscope exploration can be used without payment. Only the unlocked HD poster is paid.

Does this guarantee clear-sky visibility?

No. The calculations describe geometry. Cloud, terrain, buildings and light pollution can change what a person sees from the ground.

Do I have to buy a poster?

No. The tool stands on its own. If wanted, the watermark-free 4960 × 7016 px, 300 DPI file costs €3.99. Checkout is in euros; the card issuer shows the current conversion to US dollars (USD).
