Frequently Asked Questions
What is the time difference between AST and EET?
During standard time, Eastern European Time is 6 hours ahead of Atlantic Standard Time.
Does the Caribbean observe Daylight Saving Time?
The vast majority of Caribbean nations and territories — including Puerto Rico, the Dominican Republic, the US Virgin Islands, Trinidad and Tobago, and Barbados — do not observe Daylight Saving Time and remain on AST (UTC-4) year-round. This means these territories share the same clock as Halifax only during the Atlantic Standard Time window in winter, diverging by one hour once Canada and Bermuda advance to ADT each spring.
What is the difference between AST and ADT?
AST (Atlantic Standard Time) is the standard winter offset at UTC-4:00, observed from the first Sunday in November through the second Sunday in March across all AST regions. ADT (Atlantic Daylight Time) is the summer offset at UTC-3:00, applied by Eastern Canadian provinces and Bermuda when they advance their clocks by one hour during Daylight Saving Time.
What is the difference between EET and EEST?
EET (Eastern European Time) is the standard winter offset at UTC+02:00, observed from late October to late March. EEST (Eastern European Summer Time) is the daylight saving offset at UTC+03:00, active from the last Sunday in March to the last Sunday in October across Eastern European countries.
Is South African Time (SAST) the same as EET?
South Africa operates on SAST (UTC+02:00), which shares the same numerical offset as EET during winter. However, South Africa does not observe Daylight Saving Time, so it only aligns with EET from late October to late March — when Eastern Europe returns to its standard UTC+02:00 offset.
