The timezone AST in Barbados

Timezones are always computed by their difference to UTC, the "Universal Time Coordinated". In Barbados exists only a single tonezone at UTC-4. E.g. Los Angeles is currently at UTC-7 in Pacific Time, so the time difference between LA and Barbados is 3 hours.

Barbados has no time difference between summer and winter. A daylight saving time doesn't exist.

Barbados has an east-west extension of 0.20 degrees of longitude. Given the country's location in Caribbean, this corresponds to about 22 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 48 seconds. This means the sun rises and sets 48 seconds later in the west than in the east.

No more daylight saving time in Barbados

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 Barbados would not be particularly large. Bridgetown is located just 1,450 km from the equator. A day in midsummer would then not last from 05:32 to 18:28, but from 06:32 to 19:28. 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, in 1980, the decision was made to finally abandon daylight saving time in Barbados.
