The term "golden number" is spelled with the IPA phonetic transcription as /ˈɡoʊldən ˈnʌmbər/. The word "golden" begins with a voiced velar stop /ɡ/ followed by a long open-mid back unrounded vowel /oʊ/. "Number" starts with an unvoiced alveolar nasal consonant /n/ and a short u vowel sound /ʌ/. The combination of these words refers to a numerical sequence introduced by Euclid that identifies the number of days between new moons. This concept was important for determining dates in the Gregorian calendar.
The "golden number" is a term primarily used in the domain of mathematics and timekeeping to refer to a mathematical constant or ratio denoted by the Greek letter Phi (φ) or the symbol Φ. The golden number is an irrational number with an approximate value of 1.6180339887. It is believed to have first been discovered and extensively studied by the ancient Greeks, particularly Pythagoras and Euclid.
The golden number, also known as the golden ratio, is a unique and fascinating proportion that exhibits a symmetrical and aesthetically pleasing nature. It is derived from a special mathematical relationship where the ratio of the sum of two quantities to the larger quantity is the same as the ratio of the larger quantity to the smaller quantity.
This ratio has found significant applications in various fields such as art, architecture, design, and nature. It is often associated with beauty, balance, and harmony due to its presence in many visually appealing structures, such as the pyramids of Egypt and the Parthenon in Athens.
Moreover, the golden number also emerges in natural phenomena like the spiral arrangement of sunflower seeds, the branching of trees, and even the shape of galaxies. Its prevalence throughout the natural world has led many to believe that it signifies an inherent order and symmetry present in the universe.
To summarize, the golden number is a mathematical constant or ratio that holds considerable significance across different disciplines, representing a proportion that is visually captivating and appears throughout the realm of nature and art.

The term "golden number" has its origins in ancient Greek astronomy and mathematics. It comes from the Greek phrase "chrýsox̱éni̱ árithmos" (χρυσόξενοι αριθμοί), which translates to "golden numbers" in English. The word "chrýsos" (χρυσός) means "golden" or "golden-colored", and "xénos" (ξένος) means "strange" or "unknown".
