How do I return ONLY the name of a weekday, from a cell/cells containing that day's date,

Hello Everyone. I am new to this Forum, and this is my first ever post. As my Profile says, I used MS Office for a number of years during my work in admin and finance. However this ended in about 2008 I think, and I have become VERY rusty!!! So I need help with the following. Please don't laugh!! But, It may be THE easiest question ever posted!! A few years ago I would have done this "in my sleep", but I'm sooooo rusty that I just can't figure it out now!!

Though it is so simple, it is a part of something very important to me, which I MUST get right, so all your help is really appreciated!!! Thank you in advance.

My question:

I am starting from a blank worksheet. In one column (let's say Column A) I have today's date, 01/11/2016 (I'm using the U.K. Date Format, so 1st November, 2016). I need this to go down the rows, adding three days each time (so 4th November in Row 2, 7th November in Row 3, etc. I just did (= A2=(A1+3) etc., and did copy/paste for about 20 rows. Perfect, no probs so far!!).

NOW, in Column B, alongside each date, ALL I want it to return, is, which day of the week will this be? So next to 01/11/2016 i need just the word "Tuesday", and so on down the column.

Obviously I could just re-format the column to show "Tuesday, 1st November 2016" and so on, but, I need it just as described above: Column A: 01/11/16, 04/11/16 etc. Column B, JUST the correct word: Tuesday, then next row, Friday, and so on, no showing the whole date. I could do it manually I guess, but I will have loads of rows in the end!!

There - I did warn it was absurdly simple (at least I hope!!).

All help/suggestions are greatly appreciated!!!

Thank you.

Dag.
