Note: Displayed times and values are generated based on the astronomical formula and your location which can be approximation. The moon phase, illumination, and age are calculated using a date set to UTC (Coordinated Universal Time) noon (12:00:00) for each day, providing a consistent point for phase determination globally. For accurate moon phases dates and precise time in Brunei Darussalam click here. The moon's geocentric distance is also calculated for UTC noon of each day. Moon Rise and Set times are calculated based on the user's local time zone. There is a ~0.133 degree correction to the horizon relative to the observer's position for the moon rise/set effectively incorporates for atmospheric refraction, the effect of the Moon's horizontal parallax and semi-diameter.
