Sunset and sunrise times in Libreville, Gabon

Sitting on the western side of its time zone puts solar noon at 12:24, a full 24 minutes after twelve o'clock, and drags the whole day — sunrise, noon and sunset — along with it.

At 0.4°N the sun cuts through the twilight band at an angle, so darkness takes 21 minutes to arrive: 3 minutes shorter than today's 24-minute median.

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.

Across August the sunset moves 6 minutes earlier, averaging about 13 seconds a day.

Being inside the tropics means two zenith passages a year, 22 March and 22 September, when the sun is straight up at solar noon rather than merely high. The next one is in 4 weeks.

The longest and shortest days of the year differ by just 3 minutes here. In London the same gap is around 8.8 hours. That is about 194 times less seasonal variation.

The times barely move this week: the longest day of the year falls on 21 June, 2 months ago, so day length is changing by under a minute a day. Sunset shifts just 5 minutes earlier over the next fortnight.
