It seems that some people are still using that antiquated system of naming the days of the week, ie: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday.
I thought I would set any confusion to rest by setting out the definitions of the real days of the week. They are as follows:-
Monday: Any day that you are at work, but you weren't at work the previous day.
Tuesday: Any day that you are at work, you were at work the previous day and you will be at work the next day.
Friday: Any day that you are at work, but you won't be working the next day.
Saturday: Any day that you are not at work and you won't be working the next day.
Sunday: Any day that you are not at work, but you will be working the next day.
You should find that these definitions encompass any given day. Any claims as the existence of a Wednesday or Thursday are purely circumstantial. They were both discontinued.
