Crozet, French Southern Territories
Crozet follows UTC+4 without daylight saving time. The archipelago has no cities or permanent civilian population; local activity is centred on the Alfred Faure research base, and sunrise varies greatly through the southern seasons.

Current time in Crozet, French Southern Territories
Local civil time in the Crozet Archipelago is four hours ahead of Coordinated Universal Time. A UTC reading can therefore be converted by adding four hours, with the date moved forward when the result passes midnight.
Crozet does not change its clocks for summer or winter. This keeps local time straightforward, but the offset between Crozet and a daylight-saving location elsewhere may change during that location’s clock transitions.
A meeting in Crozet is easier to schedule by time zone than by commute: the ocean is the longer part of the journey.
A research base rather than a city
Crozet is one of the districts of the French Southern and Antarctic Lands. It is a remote subantarctic archipelago, not an urban region. Lists describing its “largest cities” can therefore be misleading.
Alfred Faure is the principal French scientific and logistical base. The base stands on Île de la Possession. There are no incorporated cities in the archipelago. Personnel stay for research, administration and technical operations rather than forming a conventional permanent town.
For clocks, weather and daylight, Alfred Faure is normally the most practical named location. Other islands in the archipelago may differ slightly in solar time because of their longitude, but they do not provide a chain of towns comparable with an inhabited province.
Sunrise in a subantarctic archipelago
Sunrise changes markedly over the year because Crozet lies well south of the tropics. Southern Hemisphere summer brings longer daylight, while winter brings shorter days. Cloud, mist and the archipelago’s frequently unsettled weather can also determine when direct sunlight is actually visible, even though the calculated sunrise is fixed by astronomy and the horizon used by the calculator.
An exact result requires a date and coordinates. Select Alfred Faure or Île de la Possession when planning activity at the base; do not substitute a distant mainland city merely because it shares UTC+4. A shared clock offset does not imply matching dawn, dusk or weather.
For fieldwork, sunrise is only one planning input. Twilight, terrain, visibility and local operational instructions may matter more than the minute when the Sun crosses a theoretical horizon. Use the published local schedule for station activities and a location-specific astronomical calculation for observation work.
Questions and answers
- What time zone does Crozet use?
- Crozet uses UTC+4 throughout the year.
- What is the largest city in Crozet?
- Crozet has no city. Alfred Faure, a research base on Île de la Possession, is its main occupied site.
- Why does the sunrise time change so much?
- Crozet’s southern latitude produces strong seasonal changes in daylight length. The exact sunrise also depends on the date and observation point.
