It is 2:16 pm in Africa/Sao_Tome
Africa/Sao_Tome is the IANA identifier for the time zone of Sao Tome in Sao Tome and Principe. It is running at UTC+0 right now, abbreviated GMT, and the local date is Saturday, September 26, 2026. The zone never moves its clocks.
What time is it in Africa/Sao_Tome right now
2:16 pm on Saturday, September 26, 2026, as this page was served, which in 24 hour form is 14:16. The clock above ticks on from there in your own browser. The offset is zero. Africa/Sao_Tome reads the same clock as Coordinated Universal Time itself, so a timestamp stored in UTC needs nothing added or taken away to be read here.
17 other zones read UTC+0 at this instant. They are interchangeable as a clock reading today and not as an identifier: storing UTC+0 instead of Africa/Sao_Tome throws away the rule that decides what they all do at the next transition.
The UTC offset of Africa/Sao_Tome
An offset of UTC+0 names the meridian of Greenwich itself. Sao Tome, Sao Tome and Principe actually sits at 6.73 degrees east, which is 6.7 degrees east of it, so the sun there runs about 27 minutes ahead of the clock before daylight saving is even considered. Zone boundaries are drawn by borders and by convenience, not by longitude, and this is the size of the gap that produces.
Because this zone never moves its clocks, UTC+0 is the answer on every day of the year. That makes it an easy zone to schedule against, with the caveat that the other end of the call may still be moving its own clocks, so the gap between the two changes even though nothing changed here.
Daylight saving in Africa/Sao_Tome
Africa/Sao_Tome does not observe daylight saving. It sits at UTC+0 in January and reads UTC+0 again in July, so a gap worked out against it today is still right in six months. It has not moved its clocks in any year since 1970 that this page can see.
The database holds no clock change for Africa/Sao_Tome in 2025, 2026 or 2027, so there is no transition table to print. The offset shown at the top of this page is the offset on every date in those three years.
How the offset of Africa/Sao_Tome has changed since 1970
Read on 1 January and 1 July of each year, which is the cheapest pair of samples that shows both the winter offset and whether the clocks moved that summer. The zone has passed through 3 distinct eras in that time and has used 2 different offsets: UTC+0, UTC+1. Its current behaviour has held since 2019. A rule change that began and ended between July and the following January is invisible to this sampling, so the table is a shape rather than a complete edit history.
| Years | 1 January | 1 July | Behaviour |
|---|---|---|---|
| 1970 to 2017 | UTC+0 | UTC+0 | one offset all year |
| 2018 | UTC+1 | UTC+1 | one offset all year |
| 2019 to 2026 | UTC+0 | UTC+0 | one offset all year |
No summer shift appears in any year sampled, so a piece of software that treats Africa/Sao_Tome as a fixed offset happens to be right, and is right by luck rather than by design: the same assumption applied to a neighbouring zone breaks twice a year.
Countries and regions that use Africa/Sao_Tome
One country uses Africa/Sao_Tome: Sao Tome and Principe, which keeps this as its only time zone and has a population of about 231,000.
Cities in the Africa/Sao_Tome time zone
This site does not yet carry a city page inside Africa/Sao_Tome, so the readings here are computed for the identifier itself and anchored at Sao Tome, Sao Tome and Principe. That costs nothing in accuracy: an offset is a property of the zone, not of a settlement, so the clock above is right for every point inside it. The city index lists the 6,338 places that do have their own page.
The sun against the clock in Africa/Sao_Tome
Worked out for Sao Tome, Sao Tome and Principe, the capital of a country that keeps the zone, at 0.33 degrees north, 6.73 degrees east. The sun rises at 5:21 am and sets at 5:28 pm, giving 12 hours 6 minutes of daylight. Solar noon, the moment the sun is highest, falls at 11:24 am, which is 36 minutes before clock noon.
That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Sao Tome, Sao Tome and Principe sitting 6.7 degrees east of the UTC+0 meridian, the equation of time, which today runs 8.6 minutes ahead of mean time, and no daylight saving at all, because this zone does not use it.
Convert Africa/Sao_Tome to another time zone
The converter is keyed on the abbreviations people type rather than on identifiers. Africa/Sao_Tome is at UTC+0 right now, the same reading as UTC, so these pages answer the same question for it today. They will diverge if the two zones ever adopt different daylight saving rules, which is exactly why the identifier is the thing worth storing.
Questions about Africa/Sao_Tome
- What time is it in Africa/Sao_Tome right now?
- 2:16 pm on Saturday, September 26, 2026, as this page was served. The clock at the top of the page ticks on from there.
- What is the UTC offset of Africa/Sao_Tome?
- UTC+0 at this instant, on every day of the year.
- Does Africa/Sao_Tome observe daylight saving time?
- No. It stays at UTC+0 all year.
- What is the abbreviation for Africa/Sao_Tome?
- GMT at this instant. It does not change, because the offset does not.
- Which countries use Africa/Sao_Tome?
- Sao Tome and Principe.
- Why store Africa/Sao_Tome instead of UTC+0?
- Because the offset is an output and the identifier is the input. This zone has one offset today and no guarantee of keeping it, and 17 other zones share its current reading while carrying different rules. A record storing UTC+0 cannot tell them apart; a record storing
Africa/Sao_Tomekeeps working through every future rule change.
