Sunset and sunrise times in Mbuji-Mayi, Democratic Republic of the Congo

From sunset to full civil darkness is 21 minutes here, against a 24-minute median elsewhere today. Latitude 6.1°S accounts for the 3-minute difference.

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 11 seconds earlier each day this month — 5 minutes from the first of September to the last.

On 5 March and 9 October the midday sun stands at the zenith, 218 days apart. Those are the only two days of the year with no noon shadow. The next one is in 13 days.

At 6.1° the seasons barely touch the clock: 43 minutes separate midsummer from midwinter, against roughly 8.8 hours in London.

At 621 m the horizon sits 0.86° lower than at sea level, so the sun sets about 3.5 minutes later here than the standard tables suggest — roughly 6.9 minutes of extra daylight across the day.

The times barely move this week: the longest day of the year falls on 21 December, in 3 months, so day length is changing by under a minute a day. Sunset shifts just 2 minutes earlier over the next fortnight.
