Did you know?
Things about French Guiana's time.
French Guiana’s single, non‑DST time zone makes it one of the easiest places in the region to keep straight—no springing forward or falling back. Its position near the equator means day length and solar noon change very little over the year, so nobody misses the seasonal clock shifts. It shares UTC-03:00 with its neighbors Suriname and the Brazilian state of Amapá.

- What time zone is used in Cayenne?
- Cayenne uses French Guiana Time, which is UTC-3 year‑round. No daylight saving time changes apply.
- When traveling from Paris, France, how many hours should I adjust in French Guiana?

- Do I need to change my watch twice a year when living in French Guiana?
- No. French Guiana does not observe daylight saving time, so the offset stays fixed at UTC-3 all year.
- How do business hours in Cayenne compare with nearby South American neighbors?
- Because French Guiana uses UTC-3 and doesn’t change its clocks, weekly schedules remain consistent, and its neighbors Suriname and the Brazilian state of Amapá are also on UTC-3 with no DST, so business hours line up.
- Will my phone automatically handle the time differences correctly in Cayenne?
- Yes. Most phones will set themselves to French Guiana Time (UTC-3) and will not add a DST offset in French Guiana.
