And you never wondered why the days are called that way weeks? Where did these and not any other names come from? What influenced their appearance? Before you understand why the days weeks are called so, you must first understand that in Old Slavonic language (and for many Slavic peoples – to this day) the word “week” had a different meaning from the modern one. So called the last day of the week (analogue of the modern week), a weekend, when they didn’t do anything. Hence, in fact, its name – “a week”. Monday. Being the first day of the week Monday retains the Old Slavonic meaning in its name “weeks”. This is the day after a week (Sunday) – Monday. Tuesday. The name of Tuesday is already clear one can see the word “second”, which is quite logical. Second day weeks or the second day after a week – both values are equivalent and true. Wednesday. The name of the medium comes from the word “middle”. Despite the apparent absurdity – after all, the “average” day of the week is the fourth, and not the third – there is an explanation for this. All the fact is that, according to religious customs, the first day of the week Sunday is considered (in many countries this tradition is preserved and still remember at least America and England). And although international standards indicate the first day of the week monday, in the title On the third day of the week, a biblical imprint is preserved. Thus, Wednesday really turns out “in the middle” of the week. Thursday and friday. And again everything is clear – the name comes from the word four, the fourth day of the week. The same goes for Friday whose name comes from the word “five.” Saturday. The name of the Sabbath day comes from the Hebrew word “Sabbath” (“Shabbat” – “peace”, “rest from work”). And indeed Jewish religion always considered Saturday to be a day of rest. Sunday. It is easy to guess that the name of the seventh day weeks associated with the great event – the Resurrection of Jesus Christ. That is why with the introduction of Christianity, the old Russian name The last day of the week was changed to Sunday. And the word “week” has since been used only in a new meaning, replacing an old Russian week. As you can see, in the answer to the question why the days of the week are so named, it was not without appeal to religious to sources. Indeed 3 of the 7 days of the week found their name due to certain events, the transition of the Slavic peoples from paganism to Christianity.
