Time Zone Converter
This time zone converter turns a time in one place into the time in another, applying each zone's own daylight-saving rule for the date you pick. It also works as a world clock, opening with Philippine Time and the current time anywhere else you add.
Why a time difference is not always the same number of hours
The Philippines keeps one offset, UTC+8, all year — the clocks never move here. Many of the countries Filipinos check against do move theirs: the United States shifts on the second Sunday of March and the first Sunday of November, and the United Kingdom, Canada and Australia each shift on their own dates too. For a few weeks every year, that changes how far ahead the Philippines is from any of them by exactly one hour.
Other places share the habit of never changing: Japan, Thailand, Vietnam, India, China and Taiwan all keep one fixed offset as well, which is why Manila to Tokyo stays a flat hour apart every single day, while Manila to Los Angeles swings between 15 and 16 hours depending on the season. This converter never assumes a difference — it looks up both places for the exact date you enter, using the time zone rules your browser already holds.
Abbreviations, and what the converter does with them
People write PST, EST or CET all year, even in the months when the place is actually on daylight time — Pacific Daylight Time on the US west coast in summer, not Pacific Standard. The converter reads an abbreviation as the region it names, applies whichever offset is actually in force there on the date you pick, then shows the abbreviation really in use, so the result matches what a clock on the wall in that place would say.
One mix-up is worth flagging for anyone searching from the Philippines: PST here means US Pacific Standard Time, not Philippine Standard Time. If you're looking for the time in the Philippines itself, Tauvio's Philippine Time page is the one to use — this converter's PST is always the US west coast. A few letters are shared for other reasons, too: IST on these pages is India Standard Time, though Israel and Ireland also use it, and UTC and GMT are both fixed at UTC+0 and never move.
Converting a time for a meeting or a call
Enter the date and time on the side where the meeting is set, and the converter gives you the same moment on every other place you've added. Check the date, not just the hour: a nine-in-the-evening call from the US west coast already lands the next afternoon in the Philippines, and a deadline written as midnight in one place can fall in the middle of the working day in another.
Add as many places as you're coordinating with, up to eight at once, and the list is remembered on this device, so it's ready the next time you open the page. Everything runs in your browser; nothing you type or add is sent anywhere.
Questions and answers
How do I convert a time between time zones?
Enter the date and time for the first place and add the second, and the converter shows the same moment there. Check the date as well as the hour — daylight saving can shift the gap by an hour depending on when you're converting.
What is the time difference between the Philippines and the US?
The Philippines is UTC+8 all year, so it's 15 to 16 hours ahead of the US west coast and 12 to 13 hours ahead of the US east coast, depending on whether US clocks are on daylight saving at the time. Add both places above for the exact gap on any date.
Does the converter handle daylight saving time?
Yes. It applies each zone's own rule for the date you enter, so a conversion for a date in July can come out an hour different from the same conversion in January — except when the Philippines is one side, since it never observes daylight saving at all.
What is the difference between UTC and GMT?
For a conversion they're the same, UTC+0. UTC is the scientific standard kept by atomic clocks; GMT is the name of the time zone the United Kingdom actually uses in winter.
Why is the gap between two places sometimes an hour off from what I expected?
Because one of the two places has just moved its clocks for daylight saving and the other hasn't — or one moves and the other never does, the way the Philippines never does. For a few weeks a year, that shifts the usual difference by an hour.
