Indochina Time to Philippine Time Conversion (ICT To PHT)

A lot of companies don’t think about this conversion until it causes problems.

You hire someone in the Philippines.

Your regional manager is in Vietnam.

Your operations team is in Thailand.

Suddenly you’ve got three different time zones trying to sync up for a Monday morning standup.

And someone’s always an hour off.

The ICT to PHT conversion is the easy one. It’s consistent. No daylight saving nonsense. No twice-a-year clock changes.

Just add one hour to ICT and you’ve got PHT.

The Basic Math

Indochina Time (ICT) is UTC+7.

Philippine Time (PHT) is UTC+8.

Neither zone uses daylight saving time. Ever.

So the conversion never changes throughout the year.

PHT = ICT + 1 hour

That’s the formula. Every time. All year.

If you need to go the other way: ICT = PHT – 1 hour

Simple pattern. ICT hour + 1 = PHT hour.

Does Daylight Saving Time Affect This Conversion?

No.

Neither Indochina Time nor Philippine Time observes daylight saving time.

Thailand, Vietnam, Cambodia, Laos, and the Philippines all stay on their standard time year-round.

This is actually one of the simplest time zone conversions you’ll deal with.

The confusion only comes in when you’re converting from a zone that does use daylight saving time (like the US or Europe) to ICT or PHT.

But between ICT and PHT themselves? Rock solid. Always one hour apart.

When You’re Building a Team Across Southeast Asia

If you’re hiring across multiple countries in the region, here’s how to think about it.

Philippines (PHT): UTC+8

Vietnam, Thailand, Cambodia, Laos (ICT): UTC+7

Indonesia (multiple zones): UTC+7 to UTC+9

Singapore, Malaysia (SGT/MYT): UTC+8

The Philippines, Singapore, and Malaysia are in the same zone. That makes coordination easy.

Vietnam and Thailand are one hour behind. Small gap, easy to manage.

If you’re running a regional team, standardize on one zone for internal communication. ICT and PHT are common choices since they cover most of Southeast Asia.

Then convert once to your HQ time zone (US, UK, AU, wherever you are).

Keep it simple. Don’t make people juggle four different time zones in their head.

What This Means for You

If you’re hiring Filipino remote workers and your operations touch Indochina Time, lock in the one-hour rule now.

ICT + 1 hour = PHT. Every time.

Put it in your onboarding docs.

Add it to your scheduling tools.

Make sure your managers know it by heart.

Then focus on the bigger question: Are you designing schedules that let people do their best work without wrecking their sleep or personal life?

Because that’s the part that actually matters.

The time zone math is easy.

The human part takes more thought.
