Time difference between Denver and Johannesburg

Johannesburg is 8 hours ahead of Denver

Denver, the United States is UTC−7 · Johannesburg, South Africa is UTC+2 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Denver goes forward on the second Sunday in March and back on the first Sunday in November and Johannesburg does not change its clocks.
