Frequently asked questions

Common questions about Gustavia's time zone, daylight saving rules, and scheduling across it. Can't find what you need? Email [email protected].

Why does AST never change in Gustavia?
Unlike most Caribbean islands, zones like AST simply don’t observe daylight saving, so the clock stays steady 24/7.
What’s the biggest scheduling advantage of Gustavia’s permanent AST?
No spring-forward or fall-back means remote teams using AST avoid the twice-yearly headaches of shifting UTC offsets.
When does the sun usually rise and set in Gustavia?
Expect sunrise around 6:30 a.m. and sunset near 5:30–6:15 p.m. all year — the daylight window barely moves.
How does Gustavia’s latitude affect its daylight?
At roughly 18° north, days are almost the same length every month, reinforcing the need for a fixed-timezone setup.
Is −240 minutes unusual for the Caribbean?
No − AST covers several islands and sidesteps daylight saving, offering a predictable offset for regional collaboration.
What’s the physical intuition behind a −240 minute offset for AST?
It means when UTC says noon, it’s only 8 a.m. in AST — a half-day mental offset keeps schedule conversions less confusing.
Does AST ever overlap with Eastern Standard Time in the U.S.?
Yes — during U.S. winter, AST lines up exactly with EST, making cross-region meetings painless.
What’s one tip for remote teams in Gustavia using AST?
Set your calendar app to display AST year-round — no seasonal adjustment needed — and sync with teammates once.
