Long weekends in Sri Lanka, 2026

11 runs of three days or more, including the ones you only get by taking a single bridge day off. National closures only, computed on a Monday–Friday week — an assumption, not something the corpus records for this jurisdiction.

How we know this

Every layer this corpus carries, whether it exists for Sri Lanka, 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 Sri Lanka — 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 One full moon, three answers Mid-Autumn is a single full moon and our records resolved it to three different dates. One of the three was legitimate. Finding the other two needed no external source at all — a corpus contradicting itself is evidence on its own. Report · Silence · 22 August 2026 You cannot search for what you did not think of A dataset assembled from the open web inherits the shape of that web without anyone choosing it. No validator catches the result, because nothing is malformed — the record is consistent, correctly sourced, and missing most of the festival.

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.
