What time is it in French Guiana?

French Guiana stays on UTC−3:00 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 3 hours behind UTC, and 2 hours ahead of New York.

Cayenne is 2 hours ahead of New York and 5 hours ahead of Los Angeles. 9am in New York is 11:00 am in Cayenne.

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 11 hours 54 minutes long in Cayenne, and holding steady — within a minute of yesterday’s. The sun peaks at 12:13 pm, 13 minutes after noon on the clock. A UTC offset is a promise that the sun is overhead at midday on one meridian, and Cayenne sits 29 minutes of solar time west of UTC−3:00’s. The rest is the equation of time, which swings about a quarter of an hour either way across the year.

Cayenne is close enough to the equator that the solar year barely happens: the longest day of 2026 is 12 hours 24 minutes and the shortest 11 hours 50 minutes — a swing of 34 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.

French Guiana’s offset has not moved once since 1970 — no daylight saving, and no change of zone.
