Time difference between Buenos Aires and London

London is 4 hours ahead of Buenos Aires

Buenos Aires, Argentina is UTC−3 · London, the United Kingdom is UTC — 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 Buenos Aires does not change its clocks and London goes forward on the last Sunday in March and back on the last Sunday in October.

Buenos Aires stays put all year while London moves, so the gap changes twice a year from London's side alone. A recurring meeting set in Buenos Aires's calendar will drift by an hour without anyone touching it.
