Use this Mountain Time to Philippine Time converter to quickly convert Mountain Standard Time (MST) and Mountain Daylight Time (MDT) to Philippine Time.
TL;DR: The Philippines is 15 hours ahead of Mountain Standard Time (MST) and 14 hours ahead of Mountain Daylight Time (MDT).
So:
- 9:00 AM MST = 12:00 AM PHT the next day
- 9:00 AM MDT = 11:00 PM PHT
- 5:00 PM MST = 8:00 AM PHT the next day
- 5:00 PM MDT = 7:00 AM PHT the next day
The Philippines stays on the same time throughout the year, while most places in the US Mountain Time Zone switch between MST and MDT for daylight saving time.
This means the Mountain Time to Philippine Time difference changes by one hour depending on the time of year.
| Mountain Time | Philippine Time |
|---|---|
| 9:00 AM MST | 12:00 AM next day |
| 9:00 AM MDT | 11:00 PM |
| 5:00 PM MST | 8:00 AM next day |
| 5:00 PM MDT | 7:00 AM next day |
If you work with remote employees, virtual assistants, clients, or businesses in the Philippines, understanding this difference can help you avoid missed meetings and one-hour scheduling mistakes.

Mountain Time to Philippine Time: Quick Explanation
The easiest way to understand the Mountain Time to Philippine Time difference is to look at the UTC offsets.
Mountain Standard Time (MST) is UTC-7.
Mountain Daylight Time (MDT) is UTC-6.
Philippine Time is UTC+8.
NIST lists Mountain Standard Time at UTC-7 and Mountain Daylight Time at UTC-6.
That creates two possible time differences:
During MST:
Philippine Time is 15 hours ahead.
During MDT:
Philippine Time is 14 hours ahead.
For example, if someone schedules a call for 10:00 AM Mountain Time, the Philippine time depends on whether the location is currently observing MST or MDT.
| Mountain Time | Philippine Time | |
|---|---|---|
| During MST | 10:00 AM MST | 1:00 AM next day |
| During MDT | 10:00 AM MDT | 12:00 AM next day |
That one-hour difference may not seem significant until someone joins a Zoom call an hour early or an hour late.
This is why you should determine whether you’re converting MST or MDT, rather than simply adding the same number of hours every time.
MST to Philippine Time Conversion Table
When Mountain Standard Time is being observed, the Philippines is 15 hours ahead of MST.
Use this MST to PHT table for quick conversions:
| Mountain Standard Time (MST) | Philippine Time (PHT) |
|---|---|
| 6:00 AM | 9:00 PM |
| 7:00 AM | 10:00 PM |
| 8:00 AM | 11:00 PM |
| 9:00 AM | 12:00 AM, next day |
| 10:00 AM | 1:00 AM, next day |
| 11:00 AM | 2:00 AM, next day |
| 12:00 PM | 3:00 AM, next day |
| 1:00 PM | 4:00 AM, next day |
| 2:00 PM | 5:00 AM, next day |
| 3:00 PM | 6:00 AM, next day |
| 4:00 PM | 7:00 AM, next day |
| 5:00 PM | 8:00 AM, next day |
| 6:00 PM | 9:00 AM, next day |
| 7:00 PM | 10:00 AM, next day |
A simple shortcut is:
MST + 15 hours = Philippine Time
For example:
3:00 PM MST + 15 hours = 6:00 AM PHT the next day
Pay close attention to the date. Starting at 9:00 AM MST, the equivalent Philippine time falls on the following calendar day.
That means a Monday afternoon meeting in Denver could already be taking place on Tuesday morning in Manila.
MDT to Philippine Time Conversion Table
Most Mountain Time locations move their clocks forward for daylight saving time and switch from MST to Mountain Daylight Time (MDT).
MDT is UTC-6, making the Philippines 14 hours ahead.
| Mountain Daylight Time (MDT) | Philippine Time (PHT) |
|---|---|
| 6:00 AM | 8:00 PM |
| 7:00 AM | 9:00 PM |
| 8:00 AM | 10:00 PM |
| 9:00 AM | 11:00 PM |
| 10:00 AM | 12:00 AM, next day |
| 11:00 AM | 1:00 AM, next day |
| 12:00 PM | 2:00 AM, next day |
| 1:00 PM | 3:00 AM, next day |
| 2:00 PM | 4:00 AM, next day |
| 3:00 PM | 5:00 AM, next day |
| 4:00 PM | 6:00 AM, next day |
| 5:00 PM | 7:00 AM, next day |
| 6:00 PM | 8:00 AM, next day |
| 7:00 PM | 9:00 AM, next day |
The shortcut during daylight time is:
MDT + 14 hours = Philippine Time
For example:
6:00 PM MDT + 14 hours = 8:00 AM PHT the next day
This can actually create a convenient work schedule. A company in the Mountain Time Zone can have an end-of-day meeting while the Filipino team member joins at the beginning of their next workday.
Philippine Time to Mountain Time Conversion Table
Sometimes you need to convert in the opposite direction.
This can be especially useful for Filipino professionals working with employers or clients in Colorado, Utah, New Mexico, or other areas that use Mountain Time.
| Philippine Time (PHT) | MST | MDT |
|---|---|---|
| 6:00 AM | 3:00 PM previous day | 4:00 PM previous day |
| 7:00 AM | 4:00 PM previous day | 5:00 PM previous day |
| 8:00 AM | 5:00 PM previous day | 6:00 PM previous day |
| 9:00 AM | 6:00 PM previous day | 7:00 PM previous day |
| 10:00 AM | 7:00 PM previous day | 8:00 PM previous day |
| 11:00 AM | 8:00 PM previous day | 9:00 PM previous day |
| 12:00 PM | 9:00 PM previous day | 10:00 PM previous day |
| 1:00 PM | 10:00 PM previous day | 11:00 PM previous day |
The previous day is one of the most important parts to remember.
If it’s Tuesday morning in the Philippines, it is generally still Monday afternoon or evening in the Mountain Time Zone.
For Filipino professionals who are new to working remotely with international companies, understanding these scheduling differences is an important first step. You can also read our guide on how to become a virtual assistant in the Philippines.
MST vs MDT Explained
When someone says Mountain Time, they may be referring to either MST or MDT.
MST stands for Mountain Standard Time and uses UTC-7.
MDT stands for Mountain Daylight Time and uses UTC-6.
Under current US rules, daylight saving time begins on the second Sunday in March and ends on the first Sunday in November. Most areas that observe Mountain Time move one hour forward during this period.
Here’s the difference at a glance:
| MST | MDT | |
|---|---|---|
| Full name | Mountain Standard Time | Mountain Daylight Time |
| UTC offset | UTC-7 | UTC-6 |
| Philippines ahead by | 15 hours | 14 hours |
| 9:00 AM becomes | 12:00 AM next day | 11:00 PM |
Philippine Time does not make this same seasonal switch.
PAGASA is responsible for maintaining and disseminating the official Philippine Standard Time, officially abbreviated PhST. The Philippines is UTC+8.
Because the Philippine side stays the same, the changing Mountain Time to Philippine Time difference comes from the US side.
If you also work with companies in other parts of the United States, see our Eastern Time to Philippine Time Converter, Pacific Time to Philippine Time Converter, or Central Time to Philippine Time Converter for the corresponding EST, EDT, PST, CST, and PDT conversions.
Does Arizona Use MST or MDT?
Arizona deserves its own section because it is one of the easiest places to get wrong when converting Mountain Time to Philippine Time.
Most of Arizona does not observe daylight saving time.
Instead, most of the state remains on Mountain Standard Time at UTC-7 throughout the year. NIST specifically lists most of Arizona as MST year-round.
That means for most of Arizona:
Philippine Time is 15 hours ahead year-round.
For example:
| Arizona Time | Philippine Time |
|---|---|
| 6:00 AM | 9:00 PM |
| 9:00 AM | 12:00 AM next day |
| 12:00 PM | 3:00 AM next day |
| 3:00 PM | 6:00 AM next day |
| 5:00 PM | 8:00 AM next day |
There is an important exception.
The Navajo Nation observes daylight saving time, even though most of Arizona does not. NIST identifies the Navajo territories in Arizona as an exception to the state’s general no-DST rule.
So if you’re scheduling with someone in Arizona, knowing the actual location can matter.
Why Arizona and Denver can show different times
This also creates an unusual situation during daylight saving time.
Denver generally moves to MDT at UTC-6, while most of Arizona remains at MST at UTC-7.
As a result, Denver and Phoenix may have the same time during part of the year and different times during another part of the year.
If you’re hiring someone in the Philippines and your company is based in Arizona, using your actual city in calendar software is safer than selecting a generic Mountain Time zone.
Mountain Time and Philippine Work-Hour Overlap
A time converter can tell you what time it is.
But if you’re managing a remote team, the more useful question is:
When are both people realistically available?
Mountain Time and Philippine working hours have limited overlap during a standard 9-to-5 schedule, but there are two practical windows.
| Mountain Time | During MST | During MDT | Best Use |
|---|---|---|---|
| 6:00 AM | 9:00 PM PHT | 8:00 PM PHT | Early US call, evening PH call |
| 7:00 AM | 10:00 PM PHT | 9:00 PM PHT | Short team meeting |
| 8:00 AM | 11:00 PM PHT | 10:00 PM PHT | Possible, but late in PH |
| 5:00 PM | 8:00 AM next day | 7:00 AM next day | US end-of-day handoff |
| 6:00 PM | 9:00 AM next day | 8:00 AM next day | Strong work-hour overlap |
| 7:00 PM | 10:00 AM next day | 9:00 AM next day | Good PH morning overlap |
This gives teams two basic approaches.
Mountain morning, Philippine evening
An early meeting in Mountain Time can fall during the evening in the Philippines.
For example:
7:00 AM MST = 10:00 PM PHT
7:00 AM MDT = 9:00 PM PHT
This can work for occasional meetings, although consistently asking someone in the Philippines to meet late at night may not be ideal.
Mountain evening, Philippine morning
Another option is to meet toward the end of the Mountain Time workday or shortly afterward.
For example:
6:00 PM MST = 9:00 AM PHT the next day
6:00 PM MDT = 8:00 AM PHT the next day
This lets the Filipino employee begin their day with a live handoff from the US team.
For companies that do not require their Filipino workers to follow a US night shift, this can be one of the most practical arrangements.
Best Meeting Times for Mountain Time and Philippines Teams
The best meeting time depends heavily on the working schedule you’ve agreed on.
If your Filipino team member works normal Philippine daytime hours, a useful overlap is often around:
5:00 PM to 7:00 PM Mountain Time
During MST, that becomes:
8:00 AM to 10:00 AM PHT the next day
During MDT, that becomes:
7:00 AM to 9:00 AM PHT the next day
Another option is:
6:00 AM to 8:00 AM Mountain Time
During MST:
9:00 PM to 11:00 PM PHT
During MDT:
8:00 PM to 10:00 PM PHT
The first option generally works better if you want your Filipino employee to maintain regular daytime hours.
There isn’t a single schedule that works for every role, though. Customer service, sales, executive assistance, development, and other jobs may require different levels of live overlap.
It’s better to agree on expected working hours before hiring rather than assuming a Filipino employee is automatically willing to work overnight.
Employers can also read our guide on Filipino work culture to better understand expectations when building a long-term working relationship with someone in the Philippines.
How to Convert Mountain Time to Philippine Time
You can calculate Mountain Time to Philippine Time manually with two simple rules.
If the time is MST, add 15 hours.
If the time is MDT, add 14 hours.
Example 1: MST
2:00 PM MST + 15 hours = 5:00 AM PHT the next day
Example 2: MDT
2:00 PM MDT + 14 hours = 4:00 AM PHT the next day
The math itself is easy.
The two things that usually cause problems are determining whether MST or MDT applies and remembering when the conversion moves into the following calendar day.
For example, during MST:
8:00 AM MST = 11:00 PM PHT
but:
9:00 AM MST = 12:00 AM PHT the next day
That one-hour change also changes the date.
Schedule Meetings Using Google Calendar
You don’t need to manually calculate every meeting once you understand how the conversion works.
Calendar tools such as Google Calendar can display a meeting in each person’s local time zone.
For example, someone in Denver can create an event in Mountain Time. A colleague in Manila whose calendar is set to Philippine Time will see the corresponding Philippine time.
This becomes particularly helpful when daylight saving time changes.
A recurring meeting may shift by an hour for the Philippine participant when the US changes between MST and MDT because the Philippines does not make the same clock adjustment.
For important meetings, it’s still smart to double-check the time and date using a Mountain Time to Philippine Time converter, especially around daylight saving transitions.
Once you’ve figured out working hours, another practical question is how to send payments internationally. See our guide on how to pay a virtual assistant from the Philippines for more information.
Common Mountain Time to Philippine Time Conversion Mistakes
Assuming Mountain Time always means MST
Mountain Time is a general term.
Depending on the date and location, someone could be observing MST or MDT.
Using the wrong one changes the Philippine conversion by one hour.
Forgetting the next-day date change
Many Mountain Time working hours fall on the following day in the Philippines.
For example:
5:00 PM Monday MST = 8:00 AM Tuesday PHT
If you only write “8:00 AM” without specifying Tuesday, you can create unnecessary confusion.
Assuming all Mountain Time locations follow daylight saving time
They don’t.
Most of Arizona remains on MST year-round, while many other Mountain Time locations switch between MST and MDT.
This is why knowing the actual city is better than relying only on a broad time-zone label.
Forgetting that the Philippines does not make the same seasonal clock change
The US side can change by an hour while Philippine time stays at UTC+8.
That means your recurring meeting may appear to shift for the person in the Philippines even though their local clocks never changed.
Using an old conversion without checking the season
If you remember that a certain meeting used to happen at 9:00 AM in the Philippines, don’t assume it will stay at 9:00 AM all year.
A Mountain Time daylight saving change can move that meeting to 8:00 AM or 10:00 AM depending on how it was scheduled.
Time-zone issues are only one part of managing an international employee. Employers should also review these common mistakes when hiring a Filipino virtual assistant before building their remote team.
Denver to Manila Time Difference
Denver is one of the most useful examples for understanding Mountain Time to Philippine Time because Colorado follows Mountain Time and observes daylight saving time.
When Denver is on MST, Manila is 15 hours ahead.
When Denver is on MDT, Manila is 14 hours ahead.
For example:
| Denver Time | Manila Time |
|---|---|
| 8:00 AM MST | 11:00 PM |
| 9:00 AM MST | 12:00 AM next day |
| 5:00 PM MST | 8:00 AM next day |
| 8:00 AM MDT | 10:00 PM |
| 9:00 AM MDT | 11:00 PM |
| 5:00 PM MDT | 7:00 AM next day |
So if a Denver-based employer schedules a 5:00 PM meeting, the Filipino employee will generally join at 7:00 AM or 8:00 AM the following day, depending on daylight saving time.
This can make Denver and Manila a surprisingly workable pairing for a late-US-day to early-Philippines-day handoff.
Utah Time to Philippine Time
Utah also follows Mountain Time, so the same MST and MDT conversions apply.
When Utah is observing MST, the Philippines is 15 hours ahead.
When Utah is observing MDT, the Philippines is 14 hours ahead.
For example:
6:00 PM MST in Utah = 9:00 AM PHT the next day
6:00 PM MDT in Utah = 8:00 AM PHT the next day
If you’re scheduling between Salt Lake City and Manila, make sure your calendar uses the actual local time zone so daylight saving changes are handled automatically.
Hiring Remote Workers in the Philippines
If you’re comparing Mountain Time to Philippine Time because you’re planning to hire in the Philippines, RemoteWork.ph connects employers directly with Filipino remote professionals.
You can search and contact talent directly, without going through a staffing agency or paying agency markups. Once you hire someone, agreeing on working hours and overlap times upfront can make communication much easier across the Mountain and Philippine time zones.

What is 5:00 PM MST in Philippine Time?
5:00 PM MST is 8:00 AM the following day in the Philippines.
This is one of the more useful conversions for remote teams because the US workday is ending as the Philippine workday begins.
What is 5:00 PM MDT in Philippine Time?
5:00 PM MDT is 7:00 AM the following day in the Philippines.
Is Mountain Time the same as MST?
Not necessarily.
Mountain Time (MT) can refer to either Mountain Standard Time or Mountain Daylight Time, depending on the location and time of year.
NIST notes that US time zones can be referred to without the standard or daylight designation when speaking generally about local time.
Does Arizona use Mountain Time?
Yes, but most of Arizona stays on Mountain Standard Time year-round instead of switching to MDT.
The Navajo Nation is an exception and does observe daylight saving time.
Does the Philippines observe daylight saving time?
The Philippines remains at UTC+8 and does not make the seasonal clock adjustment used by most Mountain Time locations in the US.
PAGASA maintains the country’s official Philippine Standard Time, or PhST.
Is PHT the same as Philippine Standard Time?
In this guide, PHT refers to Philippine Time at UTC+8.
The official Philippine government abbreviation is PhST, or Philippine Standard Time. PAGASA specifically uses PhST for the country’s official time standard.
When does Mountain Time switch between MST and MDT?
Under current US rules, daylight saving time generally begins on the second Sunday in March and ends on the first Sunday in November for areas that observe it.
Remember that most of Arizona does not make this switch.
What is the best meeting time between Mountain Time and the Philippines?
If the Filipino team member works regular daytime hours, 5:00 PM to 7:00 PM Mountain Time can be a useful window.
That generally corresponds to 7:00 AM to 10:00 AM the following day in the Philippines, depending on whether MST or MDT is being observed.
An early Mountain Time meeting around 6:00 AM to 8:00 AM can also work if the Filipino team member is comfortable meeting in the evening.
Key Takeaways: Mountain Time to Philippine Time
The most important thing to remember is:
The Philippines is 15 hours ahead of MST and 14 hours ahead of MDT.
Mountain Standard Time uses UTC-7, while Mountain Daylight Time uses UTC-6. Philippine Time remains at UTC+8.
Many Mountain Time afternoon and evening hours fall on the following calendar day in the Philippines, so always check both the time and date when scheduling.
For remote teams, one of the most practical meeting windows is often late afternoon or early evening Mountain Time, which corresponds to the following morning in the Philippines.
Also remember that Arizona is a special case. Most of Arizona remains on MST throughout the year, while most other Mountain Time locations switch between MST and MDT.
Using an accurate Mountain Time to Philippine Time converter and sending calendar invitations can help prevent one-hour mistakes, missed meetings, and confusion during daylight saving transitions.
If you’re coordinating these time zones because you’re building a remote team, RemoteWork.ph lets employers connect directly with Filipino professionals without going through an agency. Setting clear expectations around working hours and meeting availability from the beginning can make the relationship much easier for both sides.
