The concept of a weekend is a recent development that I don’t think really corresponds to what the first day of the week is (which was conceived of as Sunday for thousands of years before the weekend was invented). When the weekend was invented, Sunday as the sabbath was still a real thing for many people. I have to wonder if originally only Saturday was conceived as the weekend, followed by the week start and sabbath of Sunday. Then, as Sunday became secularized, the weekend was extended to include Sunday.
