* All times are local time for Boulder. Moonrise and moonset times are calculated for the geometric center of the Moon and account for Earth's atmospheric refraction. Dates are based on the Gregorian calendar. Illumination is calculated at lunar noon (or local noon if meridian passage is not on this day). The table may show "-" for moonrise or moonset if the event does not occur on that specific local day, or if the Moon is circumpolar (always above or always below the horizon). Two moonrises or moonsets on the same day can occur due to the Moon's orbital motion and the definition of a local day. |
