Brazil: the week starts on Sunday

In Brazil, the week is counted from Sunday, so a promotional calendar, a delivery window or a weekly sales report cut on the Monday-to-Sunday assumption is cut against the wrong week.

Anything scheduled weekly lands on the wrong days when the week is assumed rather than read.

Held since January 1, 2022How the market is physically or commercially arranged. The earliest date we are willing to say this held. It may well have been true before that; we do not backdate a record past the evidence we have read. Supported, version 1.

This entry is wrong if

The current Unicode CLDR release, or Brazil’s own labour code, states a different weekend or a different first day of the week for this market.

Written before the record was published, not after. If you can show this, send it to hello@tryorbt.com and the correction goes on the record with the entry.

Free to quote, cite and act on. Not to resell or redistribute — the sources ask that of us, and each one’s terms are named. Machine-readable: entries.json carries this record under the id omr:br:surface:working-week, with the same evidence and falsifier.

Published free, as reference, without warranty. This is not legal, regulatory, customs, tax or investment advice, and it is not a substitute for reading the primary document, which every record here names, dates and links, precisely so that you can.

We derive from public sources and we do not independently audit them. Where a source says its own records are unverified, that carries through to us. What we do promise is that every figure is recomputed from stored rows, every claim publishes the observation that would overturn it, and every correction goes on the public log. If something here is wrong, tell us and it changes in the open.
