Yes, sundaes did actually get their name from the best day of the week. In the 1890s, a few states passed laws prohibiting the sale or consumption of ice cream sodas on Sundays: it was considered immoral and improper for religious reasons. But ice cream lovers found a loophole: simply serve ice cream with toppings. The dessert came to be known as the Sunday and, eventually, the sundae.
