Kabul is in Afghanistan and is currently on UTC+4:30. Its time zone is Asia/Kabul.
Kabul does not observe daylight saving time. It stays on UTC+4:30 all year, so the difference to any other place that also holds a fixed offset never changes.
The weekend in Kabul falls on Friday and Saturday. A working day of 9:00 AM to 6:00 PM is the assumption used on the board.
