The timezone AST in Saint Kitts and NevisTimezones are always computed by their difference to UTC, the "Universal Time Coordinated". In Saint Kitts and Nevis there is only a single tonezone at UTC+. For example, New York is currently at UTC-4 in Eastern Time, so the time difference between New York and Saint Kitts and Nevis is 4 hours.
Saint Kitts and Nevis has no time difference between summer and winter. A daylight saving time doesn't exist.

Saint Kitts and Nevis has an east-west extension of 0.3 degrees of longitude. Given the country's location in Caribbean, this corresponds to about 30 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 68 seconds. This means the sun rises and sets 68 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 Lucia, Virgin Islands, Saint Vincent and the Grenadines, in parts of Greenland, on the British Virgin Islands and in the Bermudas.
No daylight saving time in Saint Kitts and NevisDue 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 the relative proximity to the equator, the impact in Saint Kitts and Nevis is not particularly large. Basseterre is only 1,950 km from the equator. A day in midsummer would then not last from 05:36 to 18:49, but from 06:36 to 19:49. 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 Kitts and Nevis.
