illumnation changes very slowly around the new and full moons and phase mostly Photography: Planning moonrise and moonset shots based on phase and illumination. . Use the lunar cycle constant (29. 53058770576 ) and calculate its duration in seconds (lunarsecs). Discover how to calculate the moon's phase for any date using a simple astronomical formula. . Explanation The phase of the Moon, also known as the lunar phase, describes the illumination of the lunar surface by the Sun as seen from Earth. View current phase, illumination, moon age, and upcoming full and new moons. This is useful for figuring out dates for new moon/ full moon which marks the beginning of numerous The algorithm is based on the following formula: h = (g + 7) % 7 where: h is the moon phase (0 = New Moon, 1 = Waxing Crescent, 2 = First Quarter, 3 = Waxing Gibbous, 4 = The script needs just a few steps to calculate the moon phase for a date and time. This algorithm is valid for years 2000 to 2018 (from 2000-01-01 to 2018-12-31). View illumination percentage, lunar age, and upcoming phases. I like the idea of outputting 'X hours until/after Full Moon" for some period around the full moon. Have I got this right? Discover how to calculate the moon's phase for any date using a simple astronomical formula. The acquired difference of days is divided by the length of a moon month - 29. Using Our Moon Phase Calculator Our calculator makes it easy to explore lunar phases: Enter any date While this is an interesting answer, my question was not about the moon phase, but rather the angle and position of the sun reflected on the moon. As I indicated in my previous post, variations in the lunar orbit mean the calculations can only be approximate. This formula returns the quarterly moon phases. The formula subtracts the known new moon date and divides by the average lunar month length, taking the integer part. enter your latitude and longitude and the number of hours difference with UT and then the lunar position is calculated (azimuth and altitude) and moon phase The formula : See this Wikipedia entry for more information on lunar cycle and calculation of moon phase. The changing position of the illumination of Since the Moon is not tidally locked to the Sun, lunar daylight and night times both occur around the Moon.
