Both word and concept of “weekend” are emphatically not of the Georgian era.

The word “weekend” is not used until 1878, the use as an adjective not until 1935.

During the Georgian era, there was no such thing as a "workweek." There was only work and the Sabbath. Or for those of privilege, there was leisure and the Sabbath. "Work" was every day except Sunday, and for some trades, work just might happen on Sunday, as well.

Saturday was often an grueling day because not only had a person been working nonstop all week, but deadlines often loomed on Saturday since working the Sabbath was bad luck and considered disrespectful (one could not even travel on Sunday without censure). Not only were workers exhausted by Saturday, they were also pressured to finish projects.

So, when did this whole “weekend” come about? Not until the tail end of the 19th century, smackdab in the middle of the Victorian era’s industrialism.

It took several decades, many lobbyists and unions, and various failed and successful attempts to get us to the Saturday and Sunday concept of a week’s end, defining the workweek as M-F.

One such attempt was lobbyists demanding half-day Saturdays so that a day of work was not missed altogether but still allowing an opportunity for additional rest or recreation before Sunday. To make this more successful, the emphasis was on community recreation over rest since recreation would not happen on Sundays, and Sunday was already considered the “rest” day. This was a mostly northern battle and occurred in the 1840s-1850s.

Another attempt was to establish the non-working days as Sunday and Monday. They called this Saint Monday. This was seen mostly only in artisan trades and established by those artisans since they had more control over their businesses than did a factory worker submissive to his employer's demands. We see Saint Monday through the 1870s and 1880s.

Not until the 1890s do we see a Saturday-Sunday weekend taking shape, the Saint Mondays having not gained traction except amongst the artisans of some regions. The northern battle of the half-day Saturday became popular amongst labour unions and spread south so that we see across many industries, a half-day Saturday plus the rest Sunday. While this is still not a full two days free for a "weekend," we see that concept closing in. The two day weekend we know now would not occur until the 20th century.
