Best Meeting Time: Seattle to Singapore
🕐 Live Timezone Overlap: Seattle & Singapore
Seattle and Singapore sit too far apart in time for a comfortable shared working day. With Singapore 15 hours ahead of Seattle, an in-hours overlap doesn't exist under a standard 9am–6pm schedule on either side. Most teams that bridge these cities lean async-first: shared docs, recorded video, and a single brief live call when a decision genuinely needs both rooms. The widget below shows the time-of-day in both cities so you can find the least painful slot.
Time Difference: Seattle and Singapore
Singapore is currently 15 hours ahead of Seattle. The live offsets are Seattle UTC-7 and Singapore UTC+8. Seattle observes daylight saving and Singapore does not, so the offset shifts twice a year if both sides aren't already aligned.
Seattle observes daylight saving time, and Singapore does not. When either side switches, the offset shifts by an hour. The US and Europe also change clocks on different weekends, so for one week in spring and one in autumn the usual offset between US and European cities is off by an hour. Always confirm with the live tool above when you're scheduling a recurring meeting that spans a DST changeover.
Best Times to Meet
Without an in-hours overlap, the practical options are a 7am call from Seattle or an 8pm call from Singapore, depending on which side is willing to flex. Many distributed teams rotate the inconvenience so the same person isn't always taking the early or late call. For one-off conversations, a recorded async message via Loom or a written brief is usually faster than negotiating a calendar slot.

Tips for Scheduling Across Seattle and Singapore
- There is no in-hours overlap, so rotate between an early start in Seattle and a late finish in Singapore on alternating weeks.
- Seattle observes daylight saving but Singapore does not, so your offset shifts twice a year. Lock recurring meetings to local time in the city that doesn't change clocks.
- Watch Singapore's holiday calendar: Chinese New Year (January or February (movable)) takes most offices offline, so plan key meetings around it.
- Send each invite with both cities' local times in the description so neither party has to do the conversion mid-day.
- With a 15-hour gap, default to async updates: a recorded video the night before is usually faster than a 30-minute call at 6am or 10pm.
Public Holidays and Working Weeks
USA runs a Monday–Friday working week with a standard public holiday calendar among the key closures. Singapore's major holidays include Chinese New Year (January or February (movable)) and National Day (08-09). Cross-check both calendars when scheduling recurring meetings: a 30-minute call in one city's holiday week typically gets a much lower attendance rate than the same slot a week later.
