London to Buenos Aires Meeting Time & Timezone Overlap

London–Buenos Aires working-hour overlap window

The shared working window is 12:00 PM – 6:00 PM in London (Europe/London), which lines up with 9:00 AM – 3:00 PM in Buenos Aires (America/Argentina/Buenos_Aires).

Hour-by-hour: London vs Buenos Aires

Daylight saving advisory

London observes daylight saving time; Buenos Aires does not. The effective time difference between the two cities therefore shifts by one hour twice a year. In 2026, the change dates that matter for this pair are:

• Spring shift in London — last Sunday of March (Europe) or second Sunday of March (North America)
• Autumn shift in London — last Sunday of October (Europe) or first Sunday of November (North America)

If you book a recurring meeting that already sits at the edge of the overlap window, expect it to drop out for roughly four weeks each spring and autumn when the windows realign.
