The Time Zone Guide for Working Remotely with a US Company from Asia

The Reality of the Time Zone Gap

Jakarta is UTC+7. New York is UTC-5 (EST) or UTC-4 (EDT). That's a 12–13 hour gap. San Francisco is even further — UTC-8, meaning a 15-hour difference. For most of the workday, your US colleagues are asleep when you're working.

This sounds terrible. But for many roles, it's actually fine — and for async-first companies, it's a non-issue.

Understanding US Time Zones

US Zone	UTC	Jakarta offset	Manila offset
Eastern (EST/EDT)	-5/-4	+12/+11	+13/+12
Central (CST/CDT)	-6/-5	+13/+12	+14/+13
Mountain (MST/MDT)	-7/-6	+14/+13	+15/+14
Pacific (PST/PDT)	-8/-7	+15/+14	+16/+15

Finding the Overlap Window

The overlap window is when both you and your US colleagues are working simultaneously. For Southeast Asia:

• With EST companies: Your 7–9 PM = their 7–9 AM. A 2-hour window is realistic.
• With PST companies: Your 10 PM – 12 AM = their 7–9 AM. Harder but doable.

Most remote companies expect 2–4 hours of overlap daily. Know your company's "core hours" before accepting an offer.

Making Async Work for You

The real secret to cross-timezone remote work is mastering async communication:

• Document everything. Write decisions, context, and blockers in Notion/Confluence. Your US colleagues should never have to wait until your overlap window to understand what you're doing.
• End-of-day summaries. Send a short Slack message at the end of your day: what you did, what's blocked, what you need. Your manager sees it when they wake up.
• Front-load questions. Before you finish for the day, dump all your questions in one message. Don't drip them one by one — by the time they answer, your day is over.
• Record async video updates. Loom is popular for this — record a 2-minute walkthrough instead of scheduling a meeting.

The Burnout Risk

The biggest danger of timezone work is scope creep into your evenings. If your company has a 9 PM standup, that's fine occasionally — but if you're regularly working until midnight to catch US hours, that's unsustainable. Set hard boundaries before you start, and confirm them in writing with your manager.

Companies That Handle This Well

Look for these signals in job descriptions:

• "Async-first" or "async communication"
• "Flexible hours" or "results-oriented"
• "We have team members across X timezones"
• Tools like Notion, Linear, Loom in the stack

Companies that have already built async culture are 10x easier to work with from Asia than companies that are "remote-tolerant" but still run synchronously.
