UTC−04:00 is a time offset that subtracts 4 hours from Coordinated Universal Time (UTC). It is observed in the Eastern Time Zone (e.g., Canada and the United States) during the warm months of daylight saving time. The Atlantic Time Zone observes it during standard time (cold months). It is observed all year in the Eastern Caribbean.
