It is 11:45 am in Atlantic/Madeira

Atlantic/Madeira is the IANA identifier for the time zone of Madeira in Portugal. It is running at UTC+1 right now, abbreviated WEST, and the local date is Friday, September 25, 2026. The zone is on its summer offset at the moment.

What time is it in Atlantic/Madeira right now

11:45 am on Friday, September 25, 2026, as this page was served, which in 24 hour form is 11:45. The clock above ticks on from there in your own browser. The offset is a whole hour ahead of UTC, so a UTC timestamp converts here by changing the hour and leaving the minutes exactly as they are.

23 other zones read UTC+1 at this instant. They are interchangeable as a clock reading today and not as an identifier: storing UTC+1 instead of Atlantic/Madeira throws away the rule that decides what they all do at the next transition.

The UTC offset of Atlantic/Madeira

An offset of UTC+1 names the meridian 15.0 degrees east. Funchal, Portugal actually sits at 16.93 degrees west, which is 31.9 degrees west of it, so the sun there runs about 128 minutes behind the clock before daylight saving is even considered. Zone boundaries are drawn by borders and by convenience, not by longitude, and this is the size of the gap that produces.

Because this zone moves its clocks, UTC+1 is only today's answer. It runs at UTC+0 for the winter part of the year and UTC+1 for the summer part, a difference of 1 hour, and any gap memorised against it is wrong for part of the year.

Daylight saving in Atlantic/Madeira

Atlantic/Madeira does observe daylight saving. The next change is on October 25, 2026: at 1:00 am local the clocks go back, and UTC+1 becomes UTC+0. That hour is repeated, so every reading inside it happens twice, which is why a wall clock time in this zone is not always a single instant.

Every clock change the database has for this zone in 2025, 2026 and 2027, with the exact local reading either side of the jump.

How the offset of Atlantic/Madeira has changed since 1970

Read on 1 January and 1 July of each year, which is the cheapest pair of samples that shows both the winter offset and whether the clocks moved that summer. The zone has passed through 2 distinct eras in that time and has used 2 different offsets: UTC+0, UTC+1. Its current behaviour has held since 1977. A rule change that began and ended between July and the following January is invisible to this sampling, so the table is a shape rather than a complete edit history.

The earliest summer shift this sampling sees here is 1977, and the zone has kept moving its clocks since. The dates the change falls on have moved several times even where the rule has not.

Cities in the Atlantic/Madeira time zone

The one city this site covers inside Atlantic/Madeira, each with a live clock and today's sunrise and sunset worked out from its own coordinate. The clock reading is a property of the identifier, so it is the same anywhere else in the zone; the sunrise is not, because that is set by latitude and longitude.

The sun against the clock in Atlantic/Madeira

Worked out for Funchal, Portugal, the city this site covers inside the zone, at 32.67 degrees north, 16.93 degrees west. The sun rises at 7:58 am and sets at 8:00 pm, giving 12 hours 3 minutes of daylight. Solar noon, the moment the sun is highest, falls at 1:59 pm, which is 119 minutes after clock noon.

That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Funchal, Portugal sitting 31.9 degrees west of the UTC+1 meridian, the equation of time, which today runs 8.3 minutes ahead of mean time, and the hour of daylight saving currently in force. Full sunrise and sunset times for Funchal.

Convert Atlantic/Madeira to another time zone

The converter is keyed on the abbreviations people type rather than on identifiers. Atlantic/Madeira is at UTC+1 right now, the same reading as BST, so these pages answer the same question for it today. They will diverge if the two zones ever adopt different daylight saving rules, which is exactly why the identifier is the thing worth storing.

Questions about Atlantic/Madeira

What time is it in Atlantic/Madeira right now?

11:45 am on Friday, September 25, 2026, as this page was served. The clock at the top of the page ticks on from there.

Portugal.

Why store Atlantic/Madeira instead of UTC+1?

Because the offset is an output and the identifier is the input. This zone alone has two offsets in a year, and 23 other zones share its current reading while carrying different rules. A record storing UTC+1 cannot tell them apart; a record storing Atlantic/Madeira keeps working through every future rule change.
