# Weekend convention

Which days count as the weekend in a market; it varies across Islamic-finance markets and drives settlement and due dates.

A weekend convention defines which days of the week are non-business days in a market. Among markets with large Islamic finance sectors, several observe a Friday and Saturday weekend, others Saturday and Sunday, and some regions within a country differ from its capital. Institutions need the convention of each market and currency involved, because a date that is a business day in one may be a weekend in another.

This entry explains a term; it is not a Shariah ruling. Approving a product is for each institution's own Shariah board and regulator.
