Quick tips & historical notes

Remember DST varies
Madrid switches between CET and CEST; Buenos Aires stays on Argentina Time (ART). That means the difference flips between 4 and 5 hours depending on the date — use Custom mode to be certain.
Best meeting windows
Late afternoon in Buenos Aires (after 4 PM) often aligns with working hours in Madrid (evening), useful for casual catch-ups; aim for morning Madrid / late-night Buenos Aires for urgent calls.
Travel prep tip
When flying from Buenos Aires to Madrid, check the Jet Lag Planner for sleep-window suggestions; eastward travel shortens evenings and can skew your circadian rhythm.
Historical time note
Spain once had a complex history of local times; modern standardization aligned Madrid to central European timezones — a reminder that timezones are as much cultural as technical.
