Caracas is in Venezuela and is currently on UTC-4. Its time zone is America/Caracas.
Caracas does not observe daylight saving time. It stays on UTC-4 all year, so the difference to any other place that also holds a fixed offset never changes.
The weekend in Caracas falls on Saturday and Sunday. A working day of 9:00 AM to 6:00 PM is the assumption used on the board.
