About the time in São Tomé
Sunrise today lands at 06:48 and sunset at 06:16 local time, giving 11h 28m of daylight. Those figures come from the city's own coordinates (-23.52, -52.51) rather than a country-wide average, so they match what you would actually see from a window in São Tomé.
São Tomé runs on America/Sao_Paulo, which puts the city UTC −3 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
São Tomé sits at latitude -23.52, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 11h 28m is one point on that curve, not a fixed value.
