Bogota is in Colombia and is currently on UTC-5. Its time zone is America/Bogota.
Bogota does not observe daylight saving time. It stays on UTC-5 all year, so the difference to any other place that also holds a fixed offset never changes.
The weekend in Bogota falls on Saturday and Sunday. A working day of 9:00 AM to 6:00 PM is the assumption used on the board.
