Sunset and sunrise times in Bandar Seri Begawan, Brunei

Sitting on the western side of its time zone puts solar noon at 12:22, a full 22 minutes after twelve o'clock, and drags the whole day — sunrise, noon and sunset — along with it.

Light lingers for 21 minutes after sunset before civil twilight ends — 3 minutes shorter than the 24-minute median across tracked cities, which is what 4.9°N buys you.

Between solstices the sunset walks 47° across the horizon — WSW in midwinter, WNW in midsummer — which is why a fixed viewpoint works only part of the year. Today's bearing is W.

Sunset drifts 19 seconds earlier each day this month — 10 minutes from the first of August to the last.

Being inside the tropics means two zenith passages a year, 2 April and 11 September, when the sun is straight up at solar noon rather than merely high. The next one is in 16 days.

Sunset lands at close to the same time all year — the annual spread in day length is only 34 minutes, compared with about 8.8 hours at London's latitude.

Around a solstice the day length flattens out, and that is where the calendar is now: the longest day is 21 June, 2 months ago, and sunset moves a mere 6 minutes earlier in the coming fortnight.
