My Grenada meeting invite keeps changing times — what gives?

It probably doesn't. Grenada stays on Atlantic Standard Time all year, though many digital calendars still try to "spring forward / fall back" automatically. For maximum reliability in the Caribbean, ask the organizer to specify 'America/Grenada' or 'UTC−4 fixed'.

If I fly from the US East Coast to Grenada, do I have to change my clocks?

In winter months both are on UTC−4, so your clock stays the same. From March to November the US East Coast moves to EDT (UTC−4) only temporarily, then falls back again — the time difference effectively flips twice a year.

Does Daylight Saving Time ever affect calls with Grenada?

Not locally — Grenada never changes its clocks. But your location might, so keep an eye on whether you're observing DST; during Northern Hemisphere summer you'll be on the same offset, while in winter you'll be an hour behind Grenada.

What does 'America/Grenada' mean in my calendar app?

That's the IANA timezone identifier chosen to keep your device up to date with Grenada's fixed UTC−4 offset. Selecting it — rather than a generic 'AST' — ensures your app never accidentally applies DST or other locale rules.

Is Atlantic Standard Time (AST) observed anywhere else?

Yes. Several Caribbean nations and Canadian provinces share the same UTC−4 offset. Check each locale's DST policy — some will 'spring forward' in summer while Grenada stays put.

Why does Grenada not observe Daylight Saving Time?

Caribbean nations receive fairly consistent daylight year-round due to their tropical latitude, so there's little practical gain from shifting clocks. Staying fixed avoids confusion with the Daylight Saving Time flips of northern trading partners.
