Best Meeting Time: Singapore to Portland
🕐 Live Timezone Overlap: Singapore & Portland
Singapore and Portland sit too far apart in time for a comfortable shared working day. With Portland 15 hours behind Singapore, 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: Singapore and Portland
Portland is currently 15 hours behind Singapore. The live offsets are Singapore UTC+8 and Portland UTC-7. Singapore does not observe daylight saving and Portland observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Singapore does not observe DST, and Portland also observes DST. 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 Singapore or an 8pm call from Portland, 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 Singapore and Portland
- There is no in-hours overlap, so rotate between an early start in Singapore and a late finish in Portland on alternating weeks.
- Portland observes daylight saving but Singapore does not, so your offset shifts twice a year. Lock recurring meetings to local time in Singapore.
- Check USA's public holiday calendar in advance: a few national holidays shift entire working weeks.
- Most multinational APAC HQs are based in Singapore; 9am-6pm is the firm norm.
- 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
Singapore runs a Monday–Friday working week with Chinese New Year (January or February (movable)) and National Day (08-09) among the key closures. USA's major holidays include a standard public holiday set. 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.
