I think most people, at least of the church-going variety, can get to Easter Monday being the day after Easter Day – April 13. And Easter Tuesday is April 14. But regularly I find, especially in the advertising world, that today, Saturday April 11 is called “Easter Saturday”. Ofcourse it is not. Easter Saturday is April 18, Easter Friday is April 17, and Easter Week follows Easter Day, it does not precede it. Palm Sunday does not commence Easter Week, it begins Holy Week.
So if there has been an advertisement selling at discount during “Easter Week”, demand that the discount price applies from the week following Easter Day!
