Los Angeles sits 9 hours behind Amsterdam through most of the year. The gap shrinks to 8 hours for a short window in spring and another in autumn, because the US and Europe change their clocks on different dates.

Both cities observe daylight saving time, but they do not switch on the same day. Europe moves on the last Sunday of March and the last Sunday of October. The US moves on the second Sunday of March and the first Sunday of November.

When Los Angeles is on Pacific Standard Time (PST, UTC-8) and Amsterdam is on Central European Time (CET, UTC+1), the difference is 9 hours. When one city has already sprung forward and the other has not, the gap drops to 8 hours.

When the Amsterdam, Los Angeles gap is 8 hours

Two windows each year produce an 8-hour difference:

  • Mid-March to the last Sunday of March: The US shifts to Pacific Daylight Time (PDT, UTC-7) on the second Sunday of March. Amsterdam stays on CET (UTC+1) until the last Sunday of March. During those one to two weeks, the gap is 8 hours.
  • Last Sunday of October to early November: Amsterdam falls back to CET on the last Sunday of October. The US remains on PDT until the first Sunday of November. The gap is 8 hours again.

The rest of the year, the difference is 9 hours.

How the Amsterdam, Los Angeles time gap shapes your calls

With a 9-hour gap, 09:00 in Amsterdam is 00:00 in Los Angeles. 17:00 in Amsterdam is 08:00 in LA. Your late afternoon lands in their early morning.

With an 8-hour gap, Amsterdam is still ahead. 09:00 in Amsterdam is 01:00 in LA. 17:00 in Amsterdam is 09:00 in LA. The usable overlap for a business call runs roughly 16:00 to 00:00 Amsterdam time, which is 08:00 to 16:00 in LA.

Scheduling a call between Amsterdam and Los Angeles

Aim for 16:00 or 17:00 Amsterdam time. That hits their early morning, the only window where a Los Angeles working day overlaps your late afternoon. Do not call at 09:00 Amsterdam time; that is midnight or 01:00 in LA. The common advice to "catch them in the morning" only works if you mean their morning, which is your late afternoon or early evening.

The 8-hour windows are brief but they are exactly when misreading the clock is most likely. During those weeks, check a live clock for both cities rather than relying on memory.
