What time is it in São Tomé & Príncipe?

São Tomé & Príncipe stays on UTC+0:00 all year. Its offset from UTC never moves, so its relationship to places that do change shifts twice a year instead — which is usually why someone checks. Right now it is on UTC, and 5 hours ahead of New York.

Sao Tome is 5 hours ahead of New York and 8 hours ahead of Los Angeles. 9am in New York is 2:00 pm in Sao Tome.

To convert a specific time rather than read the current one, the converter shows both directions with the next clock change for each.

The day is 12 hours 6 minutes long in Sao Tome, and holding steady — within a minute of yesterday’s. The sun peaks at 11:17 am, 43 minutes before noon on the clock. A UTC offset is a promise that the sun is overhead at midday on one meridian, and Sao Tome sits 27 minutes of solar time east of UTC+0:00’s. The rest is the equation of time, which swings about a quarter of an hour either way across the year.

Sao Tome is close enough to the equator that the solar year barely happens: the longest day of 2026 is 12 hours 8 minutes and the shortest 12 hours 6 minutes — a swing of 2 minutes across the whole year, against more than nine hours in northern Europe. There is no long summer evening here and no dark afternoon in December; sunset lands at much the same time every day.

São Tomé & Príncipe has kept UTC+0:00 since Tuesday, January 1, 2019, when it moved from UTC+1:00. Before that its clocks read 1 hour ahead of what they read now.
