Primary citation

The current date signal points to iaea.org. The source URL is shown visibly on the page so readers can verify late changes instead of relying only on the timer.

Freshness and review

Source policy was reviewed on 2026-04-30. Live countdown values are render-time snapshots; editorial source fields update when the tracked event dataset changes.

Operational detail

The record does not carry a reliable public start time yet, so the page avoids implying a midnight or all-day start.

Weak-date handling

The page stays crawlable and useful, but confidence copy and schema posture are deliberately weaker than a confirmed event page.

What this countdown tracks

The one-year anniversary on Sunday 28 February 2027 of the combined US–Israeli strike on Iran's nuclear facilities at Natanz, Fordow and Isfahan, conducted overnight on 27–28 February 2026. The anniversary functions as both a commemorative date in Iran and a geopolitical pressure point on which retaliation, doctrine reviews, IAEA verification milestones and US-Iran diplomatic openings tend to cluster.

About the strike

The 28 February 2026 operation combined US B-2 stealth-bomber sorties carrying GBU-57 Massive Ordnance Penetrator munitions against the deeply buried Fordow Fuel Enrichment Plant with simultaneous Israeli Air Force strikes on the surface enrichment halls at Natanz and the Isfahan uranium-conversion facility. The strikes were conducted after the September 2025 collapse of negotiations on a JCPOA-successor framework and an IAEA Board of Governors finding that Iran had reached weapons-relevant enrichment levels.

Iran's official response has so far been calibrated — symbolic missile launches, harassment of shipping in the Strait of Hormuz, and proxy operations through aligned forces in Iraq, Yemen and Lebanon — while the regime evaluates structural options including formal NPT withdrawal.

Stakes

A first-anniversary date is a typical inflection point for Iranian leadership signalling — past examples include the Soleimani assassination anniversary (3 January) and the Islamic Revolution anniversary (11 February).
IAEA verification of Iran's residual enrichment infrastructure is on a rolling cycle; a one-year anniversary report is expected.
Potential US-Iran diplomatic re-engagement under whichever administration holds the White House in February 2027.
Oil markets historically respond sharply to Iran-anniversary headlines; Brent typically prices a 3–8% risk premium around such dates.

Significance

The strike is the most consequential US military action in the Middle East since the 2003 invasion of Iraq, and the most consequential Israeli strike on a regional adversary's nuclear programme since the 1981 Osirak operation in Iraq and the 2007 Al-Kibar operation in Syria. The anniversary will frame regional press, parliamentary debate inside Iran's Majles, and IAEA diplomacy in Vienna.

Past anniversaries of comparable strikes

Osirak (Iraq, 7 June 1981) — annually marked in Israeli strategic doctrine writing.
Al-Kibar (Syria, 5–6 September 2007) — formally acknowledged by Israel only in 2018.
Soleimani strike (3 January 2020) — every annual anniversary has produced Iranian missile demonstrations and rhetorical escalation.

How to follow

The IAEA newsroom (iaea.org) publishes verification updates. Iran International, Tasnim, IRNA and Press TV provide Iranian framing; Haaretz, Times of Israel and the IDF spokesperson cover Israeli posture; the Pentagon and CENTCOM publish US-side updates. Specialist analysts include the Institute for Science and International Security (ISIS) and the International Institute for Strategic Studies (IISS).

Pair with the Iran presidential election 2028 and the broader 2026–2028 geopolitical calendar.

FAQ

When is the anniversary? 28 February 2027. Was the strike confirmed? Yes — both US and Israeli governments acknowledged the operation publicly within 72 hours. Is Iran still enriching uranium? Per IAEA reports, residual enrichment continues at degraded capacity. Has Iran withdrawn from the NPT? Under active deliberation; not formal as of late 2026.
