The timezone AST in Saint Vincent and the Grenadines

Standard time:	Atlantic Standard Time (AST)
Daylight saving time:	none

Saint Vincent and the Grenadines has an east-west extension of 0.14 degrees of longitude. Given the country's location in Caribbean, this corresponds to about 15 kilometers. With such a small extent the course of the sun at different positions in the country hardly matters. The position of the sun in the west of the country deviates from that in the east only about 34 seconds. This means the sun rises and sets 34 seconds later in the west than in the east.


The Atlantic Standard Time also applies in Anguilla, , Aruba, Barbados, in parts of Canada, in Curacao, Dominica, Grenada, Guadeloupe, Antigua and Barbuda, Caribbean Netherlands, Saint Martin, St. Martin, Martinique, Montserrat, Trinidad and Tobago, Puerto Rico, Dominican Republic, Saint Barthelemy, Saint Kitts and Nevis, Saint Lucia, Virgin Islands, in parts of Greenland, on the British Virgin Islands and in the Bermudas.

No daylight saving time in Saint Vincent and the Grenadines

Due to the sun's orbit around the equator, the days are longer in summer (June to September in the northern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).

Due to its proximity to the equator, the impact in Saint Vincent and the Grenadines would not be particularly large. Kingstown is located just 1,450 km from the equator. A day in midsummer would then not last from 05:38 to 18:35, but from 06:38 to 19:35. The effect would be quite noticeable in the evening, but the sun rising later in the morning falls at a time when many people are already awake. Thus, daylight saving time was never introduced in Saint Vincent and the Grenadines.
