Current time in Carriacou and Petite Martinique, Grenada
The dependency follows UTC−4 year-round. Because daylight-saving time is not observed, local time can be converted by subtracting four hours from UTC. The difference from places abroad may nevertheless change when those places move their own clocks.
A named zone such as America/Grenada is preferable in calendars and software. It communicates the jurisdiction as well as the offset and avoids treating a local convention as an anonymous fixed number.
The islands leave the clocks alone; overseas meeting partners are the ones likely to move the appointment.
Hillsborough, L’Esterre and Petite Martinique
Hillsborough is the main town and administrative centre on Carriacou. Other communities on the island include L’Esterre, Harvey Vale, Windward and Hillsborough’s surrounding settled areas. Petite Martinique is a smaller inhabited island northeast of Carriacou.
Choose Hillsborough for a general regional clock. Use the actual harbour for marine departure planning. Select Petite Martinique itself for island-specific sunrise. Keep UTC−4 in mind when coordinating with mainland Grenada.
All these places share the same civil time as the rest of Grenada. There is no clock change on a short journey between Carriacou, Petite Martinique and Grenada’s main island.
Sunrise for the Grenadine islands
Sunrise varies through the year even without daylight-saving time. Carriacou and Petite Martinique are close enough to share a similar daylight pattern, but their exact coordinates produce small differences in the published minute.
An unobstructed sea horizon can make an astronomical sunrise useful, yet hills, buildings, cloud banks and the observer’s elevation affect when the Sun first becomes visible. A location on the western side of an island may remain shaded after the calculated event.
For sailing or an early ferry, sunrise is only one part of the plan. Dawn begins earlier, and navigation also depends on weather, sea state and local operating schedules. For photography, select the precise viewpoint because coast orientation changes where the rising Sun appears.
