I am an employee at a Construction Company. I am in need of some important formulae for the excel files
with a large amount of data. I visited this site with useful information and knowledge.
Thank you for sharing the valuable info with all users.
Hats off to you guys..................
I m just a beginner in excel but these tips are really useful. Great work. Appreciate it.
I liked few questions from this list as well....thanks Excel Tip....for sharing such a priceless information with your users as free of cost....:)
You can also return the day of the week by formatting the cell as a day of the week.
If the dates are in Column A, and you want the days of the week in Column B, just make the formula in B1 "=A1", and copy it down the list.
Then select all of Column B and go to Format Cells... Under Category, choose Custom. In the "Type" field, enter ddd or dddd (ddd for shortened day names, dddd for the full day names).
Now you will see the actual day of the week, instead of a number, which means nothing. "3" is not a day. "Tuesday" is a day.
The other advantage is that now you can apply more functions to this data. If you want to know the day of the week 5 days before, you can't do it with your method, because 3-5 = (-2). My method will return the correct day.
