Time in Cayenne, French Guiana

Cayenne does not change its clocks
A fixed offset, all year round
Cayenne stays on French Guiana Time at UTC-03:00 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with Cayenne from a country that does change clocks. The offset between you and Cayenne is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.
When the gap to Cayenne changes
Dates in the next year where the difference shifts, by counterpart city
The difference between two cities is not a constant. It changes whenever either side moves its clocks — and because regions switch on different dates, there are short windows each year when the usual gap is wrong. These are the dates that matter for Cayenne:
New York (United States)
- From 1 November 2026: Cayenne is 2 hours ahead of New York
- From 14 March 2027: Cayenne is 1 hour ahead of New York

Day length here barely changes: 12h 24m at its longest and 11h 50m at its shortest, a difference of only 34 minutes across the whole year. Cayenne is close enough to the equator that the seasons barely register in daylight terms, which is part of why daylight saving would serve no purpose at this latitude.
