Long weekends in Iran, 2026

7 runs of three days or more, including the ones you only get by taking a single bridge day off. Computed on a Monday–Friday week. The corpus holds Friday as this jurisdiction’s statutory weekly rest — verified — but a labour code names the day it guarantees, not the days custom adds, so it is cited above rather than computed from.

How we know this

Every layer this corpus carries, whether it exists for Iran, how many records, how each is graded and when it was last looked at. The record rather than the data — enough to check a claim before relying on it.

From the Bulletin

What the corpus turned up about Iran — published when there is something, and silent when there is not.

Notice · Divergence · 22 August 2026 Mawlid an-Nabi 2026: there is no single date Thirty-seven jurisdictions appoint the Prophet's birthday and they will not all keep it on the same day. The divergence is visible in the laws themselves, before any announcement is made. Correction · Divergence · 22 August 2026 A fire festival four days after the new year it precedes Two Iranian provinces held the same festival five days apart, and one of them had it falling after the event it leads up to. Both dates were symptoms. The fault was a rule that could not express the rule.

Global Operating Calendar

Iran beside every other market you work in — the weeks that work everywhere, where office hours overlap, and which dates are estimates rather than facts.

The same dossier exists for all 241 jurisdictions, priced by depth rather than by which country it is — browse the dossiers.

We do not promise a calendar that never changes. Dates move: authorities declare holidays at short notice and publish corrections of their own. Every record here shows what stands behind it, and when a date changes we correct it, publish it, and tell the people it affects.
