How Athens's offset moves through the year

Athens keeps two offsets: UTC+2 in January and UTC+3 in July. The clocks move between them twice a year, and each move changes the difference between Athens and every place that does not move at the same instant. As of September 2026, the offset is UTC+3, so daylight saving is in effect.

The coming cycle, derived from the IANA time zone database as of September 2026: the clocks next go back 1 hour on Sunday, October 25, 2026 (Athens local date), taking the offset from UTC+3 to UTC+2. The change after that comes 154 days later, on Sunday, March 28, 2027, when the clocks go forward 1 hour and the offset returns from UTC+2 to UTC+3. Those 154 days are the standard-time part of the year for Athens.

Read those two dates alongside the partner's dates for any city you work with. If the partner does not observe daylight saving, the gap to it changes on exactly these two dates. If it does, the gap changes only where the two calendars disagree — not at all when both sides switch at the same instants, otherwise on every date where one side has shifted and the other has not yet. The table below works that out for the reference cities.

Set against the reference cities, as of September 2026: Athens's next change comes at the same instant as London's (Sunday, October 25, 2026, London date) and 7 days before New York's (Sunday, November 1, 2026, New York date). Tokyo has no change of its own scheduled within the next 15 months, so its gap to Athens moves on Athens's dates alone. Which city moves first is what shapes each of the mismatch windows set out below.

The gap to London, New York, and Tokyo across the year

The differences below were computed at build time by scanning the coming twelve months of the IANA time zone database for each pair, locating every instant at which either city changes its clocks, and reading the gap on each side of it. "As of September 2026" is the gap today; "over the year" is the full range the pair takes before the same month comes round again, from Athens's point of view.

Athens's difference from each reference city, as of September 2026. Derived from the IANA time zone database at build time.
Reference	Athens is, as of September 2026	Over the coming year	Why
London	2 hours ahead	does not change	both change clocks at the same instants
New York	7 hours ahead	6 hours ahead to 7 hours ahead	both change clocks, on different dates
Tokyo	6 hours behind	6 hours behind to 7 hours behind	only Athens changes its clocks

Two things are visible at once: the gap to London is one number all year, while the gap to New York and Tokyo is not. The mechanism in each case is set out below, with the exact instants at which the gap moves.

Athens and London

As of September 2026, Athens is 2 hours ahead of London. Both Athens and London change their clocks, and across the scanned year every clock change on one side fell at the same instant as a change of the same size on the other, so the difference held one value at every instant of that year. A meeting fixed at one wall-clock hour in Athens therefore lands at one wall-clock hour in London all year, and vice versa.

Athens and New York

As of September 2026, Athens is 7 hours ahead of New York. Both Athens and New York change their clocks, but not at the same instants. Between one side's transition and the other's, only one shift has happened, so the gap briefly holds a value it holds only inside these mismatch windows. The gap changes 4 times in the coming twelve months; the briefest such window lasts 7 days, from October 25, 2026 to November 1, 2026 (Athens dates), during which Athens is 6 hours ahead of New York.

From Sunday, October 25, 2026 at 3:00 AM (Athens time), when Athens changes clocks: Athens is 6 hours ahead of New York.
From Sunday, November 1, 2026 at 8:00 AM (Athens time), when New York changes clocks: Athens is 7 hours ahead of New York.
From Sunday, March 14, 2027 at 9:00 AM (Athens time), when New York changes clocks: Athens is 6 hours ahead of New York.
From Sunday, March 28, 2027 at 4:00 AM (Athens time), when Athens changes clocks: Athens is 7 hours ahead of New York.

Each of those windows is opened by one city's change and closed by the other's. The first, from October 25, 2026 to November 1, 2026 (Athens dates), opens when Athens's clocks go back and closes 7 days later when New York's go back. In between, New York is on daylight time and Athens on standard time, so Athens is 6 hours ahead of New York against 7 hours ahead on either side of it. The second, from March 14, 2027 to March 28, 2027 (Athens dates), opens when New York's clocks go forward and closes 14 days later when Athens's go forward. In between, New York is on daylight time and Athens on standard time, so Athens is 6 hours ahead of New York against 7 hours ahead on either side of it. Which city moves first differs from window to window, and the longest of them lasts 14 days.

Athens and Tokyo

As of September 2026, Athens is 6 hours behind Tokyo. Athens changes its clocks for daylight saving and Tokyo does not. Each Athens transition therefore moves the gap by the full size of that shift, and nothing ever moves it back except the next Athens transition. The gap changes twice in the coming twelve months, always on Athens's dates — Tokyo's calendar plays no part.

From Sunday, October 25, 2026 at 3:00 AM (Athens time), when Athens changes clocks: Athens is 7 hours behind Tokyo.
From Sunday, March 28, 2027 at 4:00 AM (Athens time), when Athens changes clocks: Athens is 6 hours behind Tokyo.

Ranked by how many of the 365 scanned days each gap spends at its most common value, from Athens's point of view: London 365 (it never moves), New York 344 (7 hours ahead), and Tokyo 211 (6 hours behind). The two kinds of movement are not alike. The gap to New York changes 4 times in the year yet is away from its usual value for only 21 days in total, because each departure ends as soon as the other city catches up. The gap to Tokyo changes only twice, but each change stands until the next one, so it spends 154 days away from its most common value.

Working hours that overlap

Assume a 9:00 AM to 5:00 PM working day in Athens and the same in each reference city. The overlap is then a plain consequence of the gap, and it changes whenever the gap does — so where a pair takes more than one gap during the year, both readings are given. As of September 2026:

London: 6 hours — 11:00 AM to 5:00 PM in Athens, which is 9:00 AM to 3:00 PM in London.
New York: 1 hour — 4:00 PM to 5:00 PM in Athens, which is 9:00 AM to 10:00 AM in New York. When Athens is 6 hours ahead of New York — the rest of the year — the overlap is 2 hours — 3:00 PM to 5:00 PM in Athens, which is 9:00 AM to 11:00 AM in New York.
Tokyo: 2 hours — 9:00 AM to 11:00 AM in Athens, which is 3:00 PM to 5:00 PM in Tokyo. When Athens is 7 hours behind Tokyo — the rest of the year — the overlap is 1 hour — 9:00 AM to 10:00 AM in Athens, which is 4:00 PM to 5:00 PM in Tokyo.

The 9-to-5 window is a convention, not a fact about anyone's hours. The Meeting Planner takes each participant's actual working hours and evaluates the overlap for the specific date, so a slot chosen in one season is still checked against the other side's clock in the next.

How does Athens time compare with UTC, London, and New York?

As of September 2026, Athens is on UTC+3 and 2 hours ahead of London and 7 hours ahead of New York. These differences shift whenever either side changes its clocks for daylight saving.

How far ahead of or behind New York is Athens over the year?

As of September 2026, Athens is 7 hours ahead of New York. Over the coming twelve months the difference ranges from 6 hours ahead to 7 hours ahead, changing 4 times, because both cities change their clocks, but not at the same instants. The dates of each change are listed on this page under "Athens and New York".

Does a standing meeting between Athens and London move during the year?

In this pairing it should not. Both Athens and London change their clocks at the same instants and by the same amount, so the shifts cancel: across the scanned year the difference held 2 hours ahead at every instant. A meeting fixed at one wall-clock hour in Athens therefore lands at one wall-clock hour in London all year, and vice versa.

Business-hours overlap

When it is 9:00 AM in Athens (as of September 2026), it is 7:00 AM in London, 2:00 AM in New York, and 3:00 PM in Tokyo. These readings shift when any of the cities changes its clocks — the Meeting Planner computes the overlap for your exact date.
