Where these units come from
Until the middle of the nineteenth century every town kept its own noon, set by the sun overhead, and nobody minded that the next town was four minutes behind. Railways ended that: a timetable cannot be written for a hundred local noons. Britain put its railways on Greenwich time in 1847, and in 1884 the International Meridian Conference in Washington chose Greenwich as the prime meridian and sketched the twenty-four-hour scheme we still use. Greenwich Mean Time was the world's reference until 1972, when Coordinated Universal Time replaced it: UTC is kept by atomic clocks and tied back to the turning Earth by leap seconds. The abbreviations on this page name standard time — the winter setting — which is why each one is a fixed number of hours rather than something that drifts through the year.
Where you meet them
A time zone becomes real the moment two people in different places have to agree on one moment: a call between offices, a flight that lands before it took off, a market that opens while you are asleep, a deadline written in somebody else's afternoon. Server logs, train and flight schedules and anything stamped with a time are kept in UTC precisely so that the question can always be settled, no matter whose clock was on the wall.
Questions people ask
What about summer time?
The offsets here are standard-time offsets, the ones a zone keeps in winter. Where summer time is observed, the same places move one hour further on for part of the year and take a different name: Central European Time becomes Central European Summer Time, Eastern Standard Time becomes Eastern Daylight Time. The switching dates are not the same in every country, and the two hemispheres change in opposite months, so for a date inside a summer-time period add an hour to whichever side observes it.
Why isn't every difference a whole number of hours?
Because offsets are decided by governments, not by geometry. India is half an hour off the hour, at UTC+05:30; Nepal is three quarters, at UTC+05:45; the Chatham Islands are at UTC+12:45. Any of these can be changed by law, and several countries have moved their offset within living memory.
Is the answer exact?
Where both units are defined in terms of one another by whole numbers, yes — the page says so above the figure, and the only rounding is in how many digits are shown. Where the ratio has no finite decimal, the page shows twelve significant digits and says the relation is approximate rather than pretending otherwise.

The rugby tournament, the horse race and the San Francisco clock
A match in the Six Nations rugby tournament kicks off at 14:15 GMT. A show at the Edinburgh festival starts in the evening. A cricket Test at Lord’s opens at 11:00. Anyone living on America’s west coast who wants to know what the clock says at home at those moments will convert WET to PST. In winter time the calculation boils down to a subtraction: eight hours. 14:15 WET becomes 06:15 PST, 20:00 WET becomes 12:00 PST, and 05:00 WET slips back to the previous evening, at 21:00 PST. Eight hours holds in summer too, between British Summer Time and PDT. Only in two short stretches, 8 to 28 March and 25 to 31 October, does the distance fall to seven hours.
The page starts from the British, Irish and Portuguese events followed in the west, then gives the rule, the tables and the two zones. The calculation runs in the browser; no figure goes to a server.
The Six Nations on a Saturday morning
The afternoon matches
Matches are usually played in two slots, one at 14:15 and one at 16:45 GMT. The first starts at 6:15 a.m. PST, the second at 8:45 a.m. PST. Californians watch rugby at breakfast.
In the mismatched weeks
In mid-March America is already on PDT while the United Kingdom is still on GMT. A match at 16:45 GMT then starts at 9:45 a.m. PDT, seven hours away rather than eight. A “convert WET to PST” calculation that is an hour out moves the match to a different part of the morning.
The Cheltenham racing festival
The time of the big race
One of the main races on Thursday starts around 15:30 GMT. On 12 March, when America is already on summer time, that is 8:30 a.m. PDT. Americans in the west see the race before the first meeting of the day.
Betting
Bookmakers close their windows a few minutes before the start. Anyone betting from California does a “convert WET to PST” calculation with the date in view, not the usual figure, because in March the gap is seven hours.
Cricket at Lord’s
The first day
A Test match begins at 11:00 BST, which is 3:00 a.m. PDT. Enthusiasts in California get up in the night or watch the repeat in the morning.
The lunch interval
The lunch break is at 13:10 BST, which is 5:10 a.m. PDT. For a fan in the west it is the pause between the night coffee and breakfast.
Royal Ascot
The afternoon races
The first race of the day starts at 14:30 BST, which is 6:30 a.m. PDT. The royal procession before it, at 14:00 BST, is at 6:00 a.m. PDT.
The big race
The final race of the day runs around 17:35 BST, which is 9:35 a.m. PDT. A “convert WET to PST” calculation done in good time shows when you can catch the last event before the working day begins.
The Edinburgh festival
Evening shows
A theatre show scheduled for 21:00 BST begins at 1:00 p.m. PDT. Californians who follow the online broadcasts see it on their lunch break.
The afternoon programme
A comedy show at 15:30 BST is at 7:30 a.m. PDT. The British programme thus stretches across the whole Californian day.
The Last Night of the Proms
The closing concert
The last evening of the concert series at the Royal Albert Hall starts around 19:15 BST, which is 11:15 a.m. PDT. Californians watch it at lunchtime.
The broadcast
Preparations shown online may begin an hour earlier, at 18:15 BST, which is 10:15 a.m. PDT. A “convert WET to PST” calculation tells you at once whether you will arrive in time.
Hogmanay in Edinburgh
The Scottish midnight
The fireworks at midnight on 31 December are, in California, at 4:00 p.m. PST. Californians can watch the Scottish New Year before their evening.
The evening of 31 December
The concert in the city centre starts at 20:00 GMT, which is 12:00 p.m. PST. Anyone who wants to see all of it does a “convert WET to PST” calculation the day before.
How to convert WET to PST: three questions and three answers
What do you subtract?
Eight hours. WET is UTC+0 and PST is UTC−8, so the Pacific is eight hours behind London, Dublin and Lisbon. The European time is written on a 24-hour clock, and 8 is taken away from it.
When do you change the date?
When the result is negative. Then add 24 and go back to the previous day. This happens for every European time before 08:00: 02:00 WET is 18:00 PST yesterday, 07:30 WET is 23:30 PST yesterday.
Which values are worth remembering?
08:00 WET is 00:00 PST. 10:15 WET is 02:15 PST. 14:15 WET is 06:15 PST. 17:00 WET is 09:00 PST. 20:00 WET is 12:00 PST. 23:45 WET is 15:45 PST. On summer time, 20:00 WEST is 12:00 PDT, the same figure.
The Pacific, seen from the European shore
Where it lies
UTC−8 is the winter clock in California, Oregon and Washington, plus nearly all of Nevada and British Columbia. With spring the same clock rises to UTC−7 and is called PDT.
What it means for you
A British poster says 14:15, but in the west it is early morning. That is why west-coast residents always convert WET to PST before they set the alarm.
Western European time in brief
Who keeps it
Mainland Portugal, Madeira, the Canary Islands and the Faroes run on WET (UTC+0). The United Kingdom and Ireland share the hour, calling it GMT, and Iceland never changes it. In summer the clock advances an hour, between the last Sunday of March and the last Sunday of October.
The Azores
The Azores sit one hour behind mainland Portugal, so against the Pacific they are seven hours apart all year.
Eight hours on the dial
Working hours
While London works from 09:00 to 17:00, California is in the night and early morning (01:00 to 09:00). When the working day is in full swing on the west coast (09:00 to 17:00), London is in late evening and night (17:00 to 01:00). The two schedules touch at a single point.
Calls
Colleagues in London phone west best at the end of their day: 16:00 WET is 8:00 a.m. PST. A call at 11:00 WET reaches 3:00 a.m. PST.
The flight
A plane that takes off from London at 13:00 WET and flies for nearly eleven hours reaches San Francisco at 16:00 PST. The ticket says 13:00 and 16:00, as for a trip of three hours.
Northern lights and volcanoes in Iceland
The forecasts
Aurora forecasts are issued at 18:00 UTC+0, which is 10:00 a.m. PST. Iceland does not change its clocks, so in summer the same hour means 11:00 a.m. PDT.
Volcano bulletins
A bulletin at 14:00 UTC+0 is from 6:00 a.m. PST. Someone following the ash cloud from afar does a “convert WET to PST” calculation and knows whether the afternoon flights are affected.
The carnival in the Canary Islands
The evening parade
The afternoon parades in Santa Cruz de Tenerife begin around 17:00 WET, which is 9:00 a.m. PST. The Canaries are on WET, like Lisbon.
The night programme
A ball at 22:00 WET is at 2:00 p.m. PST. A “convert WET to PST” calculation shows at once that the European night party is, in California, an afternoon event.
Four dates from the calendar
In midwinter
On Friday 30 January, an event at 17:00 GMT takes place at 09:00 PST on the Californian dial.
In the spring with a seven-hour gap
On Friday 20 March, the same British hour means 10:00 PDT: California advanced its clock on 8 March, the United Kingdom only on the 29th.
In summer
On Friday 7 August, 17:00 BST is 09:00 PDT. Both clocks are on summer time, so the figure is again eight hours.
In autumn
On Friday 30 October, 17:00 GMT is 10:00 PDT, because Britain set its clock back on 25 October and California only on 1 November. On Friday 4 December, 17:00 GMT is 09:00 PST.
The four weeks with a changed figure
In March
Between 8 and 28 March California is on summer time and Western Europe is not yet. The distance between WET or GMT and the Pacific is then seven hours.
In October
Between 25 and 31 October Western Europe has returned to standard time and California has not. For a week, a “convert WET to PST” calculation on the eight-hour figure gives a result an hour too late.
Colleagues in London, colleagues in Los Angeles
When they meet
Teams with members in both cities meet at 16:00 WET, which is 8:00 a.m. PST. For the Londoners it is the last hour of the day, for the Californians the first.
What stays in writing
Work that ends at 17:30 WET reaches Los Angeles at 9:30 a.m. PST, when the American colleagues are at their desks. Written notes keep the thread.
Dials from around the globe, starting at Greenwich
Subtract or add
Starting from Greenwich time, subtract five hours for New York, six for Chicago, seven for Denver and eight for Los Angeles. Add one hour for Berlin and five and a half for Delhi.
One instant, four cities
When it is 17:00 in London, it is 12:00 in New York, 11:00 in Chicago, 10:00 in Denver and 9:00 in Los Angeles. An invitation with all the hours spares the reader any convert WET to PST.
Online lectures from British universities
Lecture time
A lecture at 18:00 GMT is at 10:00 a.m. PST. Californian students follow it in the morning, before work.
Deadlines
A deadline of 23:59 GMT falls at 3:59 p.m. PST the same day. Anyone who counts the deadline by home midnight loses whole hours.
The weeks and months that need care
Period by period
The gap between WET and PST changes during the year. In 2026: 1 January to 7 March, 29 March to 24 October and 1 November to 31 December: PST is 8 hours behind WET; 8 to 28 March and 25 to 31 October: PST is 7 hours behind WET.
What to do about it
Summer labels are WEST and PDT. The form above applies the winter gap of 8 hours, so for other periods correct the answer by the difference from the figure listed. Whenever you convert WET to PST, check which period the date falls in first.
The full day, hour by hour
WET hours and their PST equivalents
00:00 WET = 16:00 PST (previous day). 01:00 WET = 17:00 PST (previous day). 02:00 WET = 18:00 PST (previous day). 03:00 WET = 19:00 PST (previous day). 04:00 WET = 20:00 PST (previous day). 05:00 WET = 21:00 PST (previous day). 06:00 WET = 22:00 PST (previous day). 07:00 WET = 23:00 PST (previous day). 08:00 WET = 00:00 PST. 09:00 WET = 01:00 PST. 10:00 WET = 02:00 PST. 11:00 WET = 03:00 PST. 12:00 WET = 04:00 PST. 13:00 WET = 05:00 PST. 14:00 WET = 06:00 PST. 15:00 WET = 07:00 PST. 16:00 WET = 08:00 PST. 17:00 WET = 09:00 PST. 18:00 WET = 10:00 PST. 19:00 WET = 11:00 PST. 20:00 WET = 12:00 PST. 21:00 WET = 13:00 PST. 22:00 WET = 14:00 PST. 23:00 WET = 15:00 PST.
Reading the rows
Every line gives a WET time and the PST time at the same instant, with a note wherever the date moves. It is the quickest check when you convert WET to PST. Minutes are not affected here. A different minute figure in an answer is a sign of a slip. Read these rows as standard-time values and check the period section for dates where the difference changes.
The :30 rows
WET to PST, thirty minutes past
00:30 WET = 16:30 PST (previous day). 01:30 WET = 17:30 PST (previous day). 02:30 WET = 18:30 PST (previous day). 03:30 WET = 19:30 PST (previous day). 04:30 WET = 20:30 PST (previous day). 05:30 WET = 21:30 PST (previous day). 06:30 WET = 22:30 PST (previous day). 07:30 WET = 23:30 PST (previous day). 08:30 WET = 00:30 PST. 09:30 WET = 01:30 PST. 10:30 WET = 02:30 PST. 11:30 WET = 03:30 PST. 12:30 WET = 04:30 PST. 13:30 WET = 05:30 PST. 14:30 WET = 06:30 PST. 15:30 WET = 07:30 PST. 16:30 WET = 08:30 PST. 17:30 WET = 09:30 PST. 18:30 WET = 10:30 PST. 19:30 WET = 11:30 PST. 20:30 WET = 12:30 PST. 21:30 WET = 13:30 PST. 22:30 WET = 14:30 PST. 23:30 WET = 15:30 PST.
Purpose of the list
These are the readings people forget to check: events at :30. Look up the WET time and read the PST time beside it instead of repeating the calculation. The gap used here is the standard winter one; the period section lists the dates on which it differs.
Ten more examples
Awkward minutes from WET to PST
01:05 WET = 17:05 PST (previous day). 03:20 WET = 19:20 PST (previous day). 05:50 WET = 21:50 PST (previous day). 07:35 WET = 23:35 PST (previous day). 10:10 WET = 02:10 PST. 13:25 WET = 05:25 PST. 16:40 WET = 08:40 PST. 19:55 WET = 11:55 PST. 22:15 WET = 14:15 PST. 23:05 WET = 15:05 PST.
Checking your work
Compare your own answer with the pattern in these rows. With a whole-hour offset the minutes are untouched; if they differ in your result, the input was misread. These rows use the standard (winter) gap; on the dates listed in the period section the gap is different.
Daily rhythm at the other end
PST time of day for chosen WET hours
06:00 WET = 22:00 PST (night). 08:00 WET = 00:00 PST (night). 10:00 WET = 02:00 PST (night). 12:00 WET = 04:00 PST (night). 14:00 WET = 06:00 PST (early morning). 16:00 WET = 08:00 PST (morning). 18:00 WET = 10:00 PST (morning). 20:00 WET = 12:00 PST (around midday). 22:00 WET = 14:00 PST (afternoon).
Using the brackets
The brackets show whether the PST hour falls at night, in the early morning, during the working day or in the evening, which helps when you must convert WET to PST for a call. These rows use the standard (winter) gap; on the dates listed in the period section the gap is different.
Checklist: how to convert WET to PST
Preparation
Check the zone names
The Azores are not on WET: they sit one hour behind mainland Portugal. PST can also mean Philippine Standard Time (UTC+8) or Pakistan Standard Time (UTC+5); here it is the North American Pacific zone.
Use a 24-hour clock
Turn a.m. and p.m. into the 24-hour form first: 4:30 p.m. is 16:30 and 12:00 a.m. is 00:00. For example, 09:15 WET becomes 01:15 PST.
After the sum
The operation
Subtract 8 hours. If the result passes midnight, correct the date: readings before 08:00 fall on the previous date.
A second example
An evening check: 22:40 WET gives 14:40 PST.
Common slips when you convert WET to PST
Adding instead of subtracting
PST trails WET: expect a smaller number, not a bigger one.
Losing the date
A WET time before 08:00 moves to the previous date. Keeping the original date produces a one-day error.
The standard figure in the wrong weeks
Do not assume that WET and PST are always the same distance apart; the period list above shows the exceptions.
Confusing the abbreviation
WET is used by mainland Portugal, Madeira, the Canary Islands and the Faroe Islands; the Azores are an hour behind. PST can also mean Philippine Standard Time (UTC+8) or Pakistan Standard Time (UTC+5); here it is the North American Pacific zone.
Frequently asked questions
How far apart are WET and PST?
8 hours, and PST is behind WET. That is the standard figure; on some dates in 2026 it differs, as the period list shows.
How do I convert WET to PST?
Subtract 8 hours from the WET time, then fix the date if the result passes midnight.
How much is 15:30 WET in PST?
07:30 PST in the standard period.
Does the answer change during the year?
Yes, on some dates; the period list above shows which.
Does the page keep what I type?
No. The calculation runs in your browser.
