Brussels vs Los Angeles Time Difference

When it is 15:00 in Brussels, it is 06:00 in Los Angeles. That 9-hour gap holds for most of the year, but the transition weeks around the clock changes create brief periods when the difference shrinks to 8 hours.

Here is how it works.

Brussels uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) in summer. Los Angeles uses Pacific Standard Time (PST, UTC-8) in winter and Pacific Daylight Time (PDT, UTC-7) in summer. Both cities move their clocks forward in spring and back in autumn, but they do it on different dates.

Brussels springs forward on the last Sunday of March. In 2026 that is 29 March. Los Angeles springs forward on the second Sunday of March, which is 8 March. That means from 8 March to 29 March, Los Angeles is already on PDT (UTC-7) while Brussels is still on CET (UTC+1). During those three weeks, the difference is only 8 hours.

In autumn, Brussels falls back on the last Sunday of October (25 October 2026). Los Angeles falls back on the first Sunday of November (1 November 2026). So from 25 October to 1 November, Brussels is on CET (UTC+1) while Los Angeles is still on PDT (UTC-7). Again, the gap is 8 hours.

The rest of the year it is a solid 9 hours.

Best times to call Brussels from Los Angeles

With a 9-hour difference, the overlap between a normal workday in LA and a normal workday in Brussels is tight.

• LA morning (08:00 to 10:00) = Brussels late afternoon (17:00 to 19:00). You can catch the end of the Brussels workday.
• LA late morning (10:00 to 12:00) = Brussels evening (19:00 to 21:00). This works for informal calls but most Brussels offices close by 18:00.
• LA afternoon (13:00 to 15:00) = Brussels night (22:00 to 00:00). Too late.

The best window: 08:00 to 10:00 LA time, which is 17:00 to 19:00 Brussels time. That is the last hour or two of the Brussels business day. If you need to speak earlier in the Brussels day, you will have to call LA in the very early morning (05:00 to 06:00 LA = 14:00 to 15:00 Brussels).

If you are in LA calling Brussels, aim for 08:00 to 10:00 LA time. If you are in Brussels calling LA, aim for 17:00 to 19:00 Brussels time.

How does the 9-hour Brussels, Los Angeles gap feel across seasons?

The clock difference stays fixed, but the light does not. In December, Brussels gets 7 hours 56 minutes of daylight. A noon video call from LA lands in a Brussels winter afternoon that is already dark. On the June solstice, Brussels gets 16 hours 31 minutes of daylight. That same call happens in full evening light. The number on the clock is identical. The experience is not.
