Hawaii to Philippine Time Converter (HST to PHT)

The Philippines is 18 hours ahead of Hawaii and that gap never changes.

Hawaii Standard Time (HST) sits at UTC-10. Philippine Time (PHT) sits at UTC+8. That’s an 18-hour difference.

Neither Hawaii nor the Philippines observes daylight saving time, so this is fixed year-round. No seasonal adjustments, no twice-a-year surprises.

Quick examples:

• 9:00 AM HST = 3:00 AM PHT (next day)
• 12:00 PM HST = 6:00 AM PHT (next day)
• 3:00 PM HST = 9:00 AM PHT (next day)
• 6:00 PM HST = 12:00 PM PHT (next day)

Common HST to PHT Conversion Examples

These are the conversions that come up most when scheduling between Hawaii and the Philippines.

• 6:00 AM HST = 12:00 AM PHT (midnight, next day)
• 8:00 AM HST = 2:00 AM PHT (next day)
• 9:00 AM HST = 3:00 AM PHT (next day)
• 12:00 PM HST = 6:00 AM PHT (next day)
• 3:00 PM HST = 9:00 AM PHT (next day)
• 5:00 PM HST = 11:00 AM PHT (next day)
• 6:00 PM HST = 12:00 PM PHT (next day)

Your entire morning — 7:00 AM to 12:00 PM HST — falls between 1:00 AM and 6:00 AM in the Philippines.

Your lunch hour is their sunrise. Your mid-to-late afternoon (3:00 PM to 6:00 PM HST) is the only window that lands during normal Philippine working hours (9:00 AM to 12:00 PM PHT).

What Is the Time Difference Between Hawaii and the Philippines?

Hawaii Standard Time (HST) is UTC-10. Philippine Time (PHT) is UTC+8. The gap is exactly 18 hours, with the Philippines always ahead.

Because neither country uses daylight saving time, this difference holds every day of the year — January or July, it doesn’t change.

Basically when it’s Monday afternoon in Hawaii, it’s already Tuesday morning in Manila. The date flip happens at 6:00 AM Hawaii time.

Before that, both countries share the same calendar day. After that, the Philippines is a full day ahead.

Is Hawaii Always 18 Hours Behind the Philippines?

Yes. Unlike most US time zones, Hawaii does not observe daylight saving time. The Philippines also keeps the same offset year-round.

This makes HST to PHT one of the simpler conversions to work with once you know the number — no seasonal tables, no spring-forward adjustments, no checking which version is currently active. It’s always 18 hours.

Add 18 hours to any Hawaii time to get Philippine Time. Subtract 18 hours from any PHT to get Hawaii time.

Best Hours for Real-Time Meetings Between Hawaii and the Philippines

The sweet spot for live calls is roughly 3:00 PM to 6:00 PM Hawaii time.

That window lands at 9:00 AM to 12:00 PM PHT — standard morning hours in the Philippines. It’s the only part of the Hawaii workday that overlaps with normal Philippine business hours without asking anyone to be up in the middle of the night.

If you’re building a standing meeting schedule, anchoring it in this window protects your Filipino team member’s health and makes recurring collaboration sustainable.

For a deeper look at how to factor time zones into your hiring plan from the start, this guide on the best time to hire Filipino remote workers covers the scheduling considerations worth thinking through before you post a job.

Common Schedule Models for Hawaii and Philippine Teams

There are three approaches Hawaii-based employers typically use when building remote teams in the Philippines.

Full overlap schedule

Your 9:00 AM to 5:00 PM Hawaii workday becomes 3:00 AM to 11:00 AM PHT. Maximum real-time collaboration (calls whenever needed, live customer support, immediate responses).

But your Filipino team member is working a full graveyard shift. They sleep after clocking out at 11:00 AM and treat daytime as their night.

Partial overlap schedule

Shift your collaboration window to late afternoon. A 2:00 PM to 5:00 PM Hawaii overlap lands at 8:00 AM to 11:00 AM PHT — normal morning hours for the Philippines.

Your hire works a real morning, you get three solid hours of daily overlap, and the rest runs async. More documentation required, but dramatically more sustainable than full alignment.

Philippine daytime with rare overlap

Let your hire work a standard 9:00 AM to 6:00 PM Philippine schedule. Deep work, queued tasks, documented updates left for you to review when you start your day. You join an occasional late evening or early morning call in Hawaii when something genuinely needs a live conversation. When it’s set up properly, it’s the most sustainable model of the three.

How to Use the 18-Hour Time Gap for Extended Coverage

Most Hawaii employers see the 18-hour gap as a scheduling problem. The companies that do this well see it differently.

You work during your day. Your Filipino team member works during their day — which is your night. Together, that’s close to 24-hour coverage.

This only works with solid async systems in place. But when it works, it turns a wide time gap into a genuine operational advantage.

For practical guidance on building communication rhythms and workflows that hold up across this kind of gap, working with Filipino remote workers across different time zones goes deeper on the day-to-day side.

Key Takeaways on HST to PHT Conversion

The 18-hour gap between Hawaii and the Philippines is the widest you’ll encounter in US-to-Philippines hiring. But it’s fixed and predictable — no seasonal changes, no DST surprises.

The 3:00 PM to 6:00 PM Hawaii window is your most reliable time for live meetings. Everything outside that window requires good async systems.

Be clear about expected overlap hours in your job posting. Compensate fairly when you’re asking someone to work through their night. Build documentation habits from day one.

The gap is real. But it’s entirely workable when you plan around it from the start.

FAQ

How long is Hawaii standard time to PH time?

Hawaii Standard Time (HST) is 18 hours behind Philippine Time (PHT). HST is UTC-10 and PHT is UTC+8. Neither Hawaii nor the Philippines observes daylight saving time, so this 18-hour gap is fixed year-round. Add 18 hours to any HST time to get the equivalent PHT.

What is the time gap between Hawaii and the Philippines?

The time gap is exactly 18 hours, with the Philippines ahead. This is one of the largest time differences between a US state and the Philippines, and it never changes since neither location adjusts for daylight saving time.

Is PHT the same as UTC?

No. Philippine Time (PHT) is UTC+8, meaning it is 8 hours ahead of Coordinated Universal Time (UTC). UTC itself has no offset — it is the baseline from which all time zones are calculated. PHT is consistent year-round because the Philippines does not observe daylight saving time.

Is HST Hawaii Standard Time?

Yes. HST stands for Hawaii Standard Time and runs at UTC-10. Unlike most US states, Hawaii does not observe daylight saving time, so HST is the only offset Hawaii uses — there is no Hawaii Daylight Time. This makes HST one of the few US time zones with a permanent, unchanging offset.
