Convert WET to UTC Western European Time ↔ Coordinated Universal Time Free Online Secure
Western European Time and Coordinated Universal Time read the same on the clock — the offset is zero. Type a time in WET and it comes back unchanged in UTC, which is the honest answer; what differs between the two names is explained below.

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.

From a Lisbon clock to the clock that systems write
A hiking guide in Madeira says the levada walk starts at 08:30. A football club in Lisbon schedules its home match for 20:30. An observatory on La Palma opens its dome at dusk. All of these are times on the local clock, which is WET in winter and WEST in summer, and anyone who keeps records, flight plans or server logs in UTC has to convert WET to UTC. In winter the job is the shortest in this whole family: copy the hours and minutes, because the offset is zero. In summer, when the clock is WEST at UTC+1, subtract one hour: 20:30 WEST is 19:30 UTC, and 00:30 WEST is 23:30 UTC on the previous date.
The page explains how to convert WET to UTC in each season, which neighbours do not follow the same rule, and how it plays out in sailing, football, tennis, hiking and astronomy. All arithmetic runs in your browser, and nothing you type is sent to a server.
How to convert WET to UTC
In winter, leave the time alone
WET is UTC+0, the same as UTC. From the last Sunday of October to the last Sunday of March, 18:40 WET is 18:40 UTC and 23:55 WET is 23:55 UTC on the same date. You neither add nor subtract anything.
In summer, subtract one hour
From 29 March to 25 October 2026 the wall clock in mainland Portugal, Madeira, the Canaries and the Faroes is WEST, UTC+1. Then 18:40 WEST is 17:40 UTC, and 00:30 WEST is 23:30 UTC on the previous date. The form above shows the winter value, so for a date in summer take one hour off the result.
A quick clue
If a document says WEST, subtract an hour. If it says WET, copy the time. If it merely says “Portuguese time”, find out the date first.
The clock of Portugal and its islands
Where it applies
WET is the winter clock of mainland Portugal, Madeira, the Canary Islands and the Faroe Islands. The best-known cities are Lisbon, Porto, Faro, Funchal, Las Palmas, Santa Cruz de Tenerife and Tórshavn. From the last Sunday of March to the last Sunday of October the same places use WEST.
The Azores, Morocco, Iceland
The Azores sit one hour behind mainland Portugal: UTC−1 in winter and UTC+0 in summer. Morocco keeps UTC+1 for almost the whole year. Iceland stays on UTC+0 and never changes its clock. None of them follows the rule above.
UTC as the target of every technical record
Why it is requested
Audit registers, security logs, flight plans and the databases of international firms keep their times in UTC, because that scale belongs to no country’s calendar. A time written in UTC means the same in Lisbon, Singapore and São Paulo.
The standard form
A timestamp 2026-07-20T14:00:00+01:00 is the same instant as 2026-07-20T13:00:00Z. In winter, 2026-01-20T14:00:00+00:00 equals 2026-01-20T14:00:00Z. Either way the move is a request to convert WET to UTC, which date libraries perform by reading the offset.
Nothing in winter, one hour in summer
The working day on two dials
A Lisbon team working 09:00 to 17:00 occupies the same hours on the UTC dial in winter. In summer the same wall-clock hours occupy 08:00 to 16:00 UTC. A North American client reading a UTC log may think the Portuguese team starts earlier in July than in January.
Mail across the Atlantic
An e-mail sent from Lisbon at 16:30 WEST in July reaches a New York head office at 15:30 UTC, which is 11:30 EDT. The same e-mail sent at 16:30 WET in January reaches it at 16:30 UTC, which is 11:30 EST. For New York the gap is the same in both seasons, since both places move their clocks.
Flying to London
A flight from Funchal that leaves at 13:00 WEST in July leaves at 12:00 UTC. It takes about four hours and lands at 16:00 UTC, which is 17:00 BST. The ticket shows 13:00 and 17:00, and the printed duration is the real one, since Funchal and London keep the same clock.
Lisbon’s June festivals
The night of Saint Anthony
Lisbon celebrates Saint Anthony on the night of 12 to 13 June, with street parties in the old quarters. In June the clock is WEST, so midnight local time is 23:00 UTC on 12 June. A viewer in Bucharest sees the stroke of midnight in Lisbon at 01:00 EEST.
The procession
The afternoon procession on the 13th starts at 17:00 WEST, which is 16:00 UTC. A British audience watches at 17:00 BST. A “convert WET to UTC” calculation done with the date in view tells you when to open the stream.
Motor racing at Portimão
The start of the main race
The Algarve circuit hosts a motorcycle Grand Prix in autumn. The main race starts at 14:00 local time, which is 13:00 UTC while Portugal is still on WEST and 14:00 UTC after the clocks go back on 25 October. In the first case British viewers see it at 14:00 BST.
Qualifying
Saturday qualifying takes place around midday, say 12:00 WEST, which is 11:00 UTC. A programme published in UTC needs one hour added to give the local time, and one hour subtracted for the opposite direction.
The Faroese national day
Two days in July
The national festival of the Faroe Islands takes place on 28 and 29 July. The opening of the parliament on the second day happens around 11:00 WEST, which is 10:00 UTC. Danish broadcasters, on CEST, begin at 12:00.
The long light
In summer the sun rises at about 04:30 and sets after 22:30 local time in Tórshavn. In UTC those are 03:30 and 21:30. Anyone who must convert WET to UTC for a morning programme will see that the festival begins early, but in full daylight.
Summer concerts in Lisbon
Evening sets
Large June festivals feature sets that begin at 21:00 WEST, or 20:00 UTC, and run past midnight. A set that ends at 02:00 WEST ends at 01:00 UTC. Fans in London who stream it see the end at 02:00 BST.
Gates
Gates open at 17:00 WEST, which is 16:00 UTC. A visitor whose flight lands at 15:20 UTC has less than an hour: 16:20 on the local clock.
Flight plans and the airline view
Time in the filed plan
Flight plans are filed in UTC. A flight that leaves Lisbon at 15:30 WEST in July carries 14:30Z in its plan. In winter, a departure at 15:30 WET carries 15:30Z. A pilot who revises the plan has to allow for the season.
Passengers
A passenger’s ticket shows the local time. Anyone rebuilding a booking from an airline message in UTC performs a “convert WET to UTC” calculation with the label WEST or WET according to the date.
The stock exchange and Iberian markets
Session hours
The Lisbon exchange belongs to a pan-European group and keeps the group’s hours. The 09:00 CET opening is 08:00 UTC in winter and 07:00 UTC in summer. On the Lisbon wall clock it is 08:00 all year, so a Portuguese trader begins an hour before a colleague in Madrid.
What follows
A results announcement “at 09:00 Madrid time” is at 08:00 UTC, and at 08:00 on the clock in Lisbon in winter. Anyone who works in both cities keeps in mind that Portugal is an hour behind Spain.
Cables, data centres and networks
Maintenance windows
Operators of submarine cables announce maintenance windows in UTC. A window from 02:00 to 06:00 UTC is from 02:00 to 06:00 WET in winter and from 03:00 to 07:00 WEST in summer. Whoever coordinates the work from Bucharest adds two hours to the UTC time in winter and three in summer.
Incident reports
A report that says “outage from 03:10 WEST” means 02:10 UTC. If it is copied into a central system without conversion, the event appears to begin an hour later.
Universities and exams in Portugal
Class hours
Lectures at Portuguese universities start at 09:00 or 10:00 local time. In winter these are 09:00 and 10:00 UTC. In summer they are 08:00 and 09:00 UTC. Exchange students from Romania, who follow online, add two hours to the Portuguese time all year round.
Exams
An exam at 14:00 WEST in June starts at 13:00 UTC. A student in Italy, on CEST, starts at 15:00. Do the “convert WET to UTC” calculation with the date in mind, and nobody turns up an hour late.
Excursions in the Canary Islands
Fixed local times
Excursions in the Canaries are advertised in local time. A departure at 08:30 WET in January is at 08:30 UTC, and one at 08:30 WEST in July is at 07:30 UTC. Agencies in Central Europe see the departure an hour later than the Canarian clock.
Transfers
A flight that lands at 15:40 UTC in July lands at 16:40 on the island clock. A transfer you booked for 17:00 WEST therefore waits less than an hour after landing.
Zones around the Atlantic, counted towards UTC
How much to subtract
For Lisbon, the Canaries, Madeira and the Faroes, subtract zero in winter and one hour in summer. For the Azores add one hour in winter and nothing in summer. For Morocco subtract one hour for most of the year. For Iceland subtract nothing.
The same moment in several places
If it is 12:00 in Lisbon in January, it is 11:00 in Ponta Delgada, 13:00 in Madrid, 14:00 in Bucharest and 12:00 in UTC. With these anchors, any request to convert WET to UTC can be checked quickly.
Dated examples
January
On Tuesday 20 January, 15:00 on a Lisbon clock is 15:00 UTC. No difference arises in winter.
After the March change
On Tuesday 31 March, 15:00 WEST is 14:00 UTC, since the clocks moved on the 29th.
July
On Tuesday 21 July, 15:00 WEST is again 14:00 UTC, with one hour of difference throughout the warm season.
November
On Tuesday 3 November, 15:00 WET is 15:00 UTC, because the clocks went back on 25 October.
How the clock changes affect this pair
The year in segments
The gap between WET and UTC changes during the year. In 2026: 1 January to 28 March and 25 October to 31 December: WET and UTC read the same hour; 29 March to 24 October: UTC is 1 hour behind WET.
What to do about it
In the summer periods the labels are WEST and UTC. The calculator above uses the winter gap of 0 hours. For other dates, adjust the result by the difference between that figure and the gap listed for the period. Before you convert WET to UTC, find the period that contains your date.

A short guide
Each entry converts one full hour from WET to UTC, flagging any change of date. If you only need to convert WET to UTC once, the form above is quicker; for many readings, keep this chart at hand. Only the hour moves. Minutes pass through unchanged, which makes this pair easy to check by eye. These rows use the standard (winter) gap; on the dates listed in the period section the gap is different.

A note on the list
Schedules often use :30 slots. Each entry below gives the UTC equivalent, so you do not have to convert WET to UTC again for them. The gap used here is the standard winter one; the period section lists the dates on which it differs.
Odd times, converted
Ten WET times and their UTC equivalents
01:05 WET is 01:05 UTC. 03:20 WET is 03:20 UTC. 05:50 WET is 05:50 UTC. 07:35 WET is 07:35 UTC. 10:10 WET is 10:10 UTC. 13:25 WET is 13:25 UTC. 16:40 WET is 16:40 UTC. 19:55 WET is 19:55 UTC. 22:15 WET is 22:15 UTC. 23:05 WET is 23:05 UTC.
Observation
Real schedules are rarely on the hour, so here are ten with awkward minutes. 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.
The rhythm of the day in UTC
Even-numbered WET hours seen from UTC
06:00 WET is 06:00 UTC (early morning). 08:00 WET is 08:00 UTC (morning). 10:00 WET is 10:00 UTC (morning). 12:00 WET is 12:00 UTC (around midday). 14:00 WET is 14:00 UTC (afternoon). 16:00 WET is 16:00 UTC (afternoon). 18:00 WET is 18:00 UTC (evening). 20:00 WET is 20:00 UTC (evening). 22:00 WET is 22:00 UTC (night).
Reading the labels
For every second hour of the WET day the list gives the UTC time and a word for the part of the day there. Use it to decide whether a request to convert WET to UTC gives a polite hour. Read these rows as standard-time values and check the period section for dates where the difference changes.
Checklist: how to convert WET to UTC
First
Confirm the zones
WET is used by mainland Portugal, Madeira, the Canary Islands and the Faroe Islands; the Azores are an hour behind. UTC never changes with the seasons, so the suffix Z always means the same instant everywhere.
Use a 24-hour clock
Write 4:30 p.m. as 16:30 and 12:00 a.m. as 00:00 before you start. For example, 09:15 WET becomes 09:15 UTC.
Then
The operation
Copy the hours and minutes: in the standard period no date can change. For dates in the summer period listed above, apply the summer gap from that list instead.
A second example
Late in the evening, 22:40 WET becomes 22:40 UTC.
Common slips when you convert WET to UTC
Copying in the wrong season
WET and UTC share one offset in the standard period, so the hours are simply copied. In the summer period listed above the gap is no longer zero, and copying would leave the answer an hour out.
The standard figure in the wrong weeks
Do not assume that WET and UTC are always the same distance apart; the period list above shows the exceptions.
Confusing the abbreviation
Iceland shares the offset of WET all year but has no summer time, unlike Portugal. Zulu time and the letter Z mean the same as UTC.
Questions and answers
What is the difference between WET and UTC?
Zero hours, and WET and UTC agree. That is the standard figure; on some dates in 2026 it differs, as the period list shows.
How do I convert WET to UTC?
Copy the hours and minutes in the standard period; in the summer period listed above, adjust by one hour.
How much is 21:45 WET in UTC?
21:45 UTC in the standard period.
Do the seasons affect this conversion?
Yes, on some dates; the period list above shows which.
