How the gap moves through the year

Singapore is 15 hours ahead of Los Angeles for about 8 months of the year.

Singapore is 16 hours ahead of Los Angeles for about 4 months of the year.

From the second Sunday in March (when Los Angeles moves forward), Singapore is 15 hours ahead of Los Angeles.

From the first Sunday in November (when Los Angeles falls back), Singapore is 16 hours ahead of Los Angeles.

Los Angeles moves its clocks forward one hour on the second Sunday in March at 2:00 am local time and back on the first Sunday in November at 2:00 am, switching between Pacific Standard Time (UTC−8) and Pacific Daylight Time (UTC−7).

Singapore does not change its clocks: it stays on UTC+8 (Singapore Standard Time) all year.

Next clock change for this pair, as of when this page was built (2026-10-20): Los Angeles falls back on Sun 1 November 2026.

Everything on this page also holds if you swap Los Angeles for Tijuana, San Diego, San Francisco, Seattle or Las Vegas, or Singapore for Shanghai, Beijing, Guangzhou, Shenzhen or Taipei — those cities follow exactly the same clock all year.

Working hours that overlap

In January, two 9-to-5 days never meet — not a single quarter-hour is inside working hours in both cities.

July is no different.

Stretching both days to 8:00–18:00 opens 2 hours (4:00 pm–6:00 pm in Los Angeles). Beyond that, one side has to take an early-morning or evening call.

Across the week

At 9:00 on a Monday morning in Los Angeles, it is 1:00 am on Tuesday in Singapore — already a day ahead there.

8 hours of a Los Angeles working week (Monday to Friday, 9 to 5) fall on the weekend in Singapore, so part of Monday or Friday is lost for meetings.

The other way round, 7 hours of a Singapore working week fall on the Los Angeles weekend.

Daylight, distance and night calls

Los Angeles and Singapore are about 14,120 km (8,780 miles) apart and 138° of longitude apart, which by the sun alone would be 9 hours 15 minutes.

Los Angeles's winter clock sits within 7 minutes of the sun, and Singapore's runs 1 hour 5 minutes ahead of the sun.

In mid-January the sun is up in Los Angeles from about 6:58 am to 5:05 pm, and the sun is up in Singapore from about 7:12 am to 7:15 pm; both cities are in daylight at the same time for about 2 hours.

In mid-July the sun is up in Los Angeles from about 5:52 am to 8:05 pm, and the sun is up in Singapore from about 7:05 am to 7:16 pm; both cities are in daylight at the same time for about 4 hours.

In January, 5 hours of a Los Angeles office day fall in Singapore's night (10 pm to 6 am), and 3 hours of a Singapore office day fall in Los Angeles's night.

In July, 6 hours of a Los Angeles office day fall in Singapore's night (10 pm to 6 am), and 4 hours of a Singapore office day fall in Los Angeles's night.

Two usual compromises in January: an early call at 7:00 am in Los Angeles is 11:00 pm in Singapore; a late call at 6:00 pm in Los Angeles is 10:00 am the next day there.

Common mistakes with Los Angeles and Singapore

  • Forgetting that the gap changes even though Singapore never touches its clocks: Los Angeles does, so a meeting fixed in Singapore time moves by an hour for people in Los Angeles.
  • Getting the date wrong. With a gap this large, an afternoon call in one city is the next morning — or the previous evening — in the other. Write the date for both cities in the invite.
  • Writing “PST” all year for Los Angeles. In summer the zone is Pacific Daylight Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
