## Tips & Tricks 80 ā Last Working Day of the Month If a Date is Given

By |Saturday, February 28th, 2015|Categories: Tips and Tricks|Tags: , |0 Comments

If A1 holds a date, the formula for calculating last Working Day of the month would be

=WORKDAY(EOMONTH(A1,0)+1,-1)

The above formula assumes that your weekends are Saturday and Sunday.

But, if your weekends are different (e.g. in gulf countries), you can use following formula -

=WORKDAY.INTL(EOMONTH(A1,0)+1,-1,"0000110")

Where 0000110 is a 7 character string, 1 represents a weekend and 0 is a working day. First digit is Monday and last digit is Sunday. The above example is for Gulf countries where Friday and Saturday are weekends.

You also have option to give a range which has holidays. In that case, your formula would become

=WORKDAY(EOMONTH(A1,0)+1,-1,D1:D10)

=WORKDAY.INTL(EOMONTH(A1,0)+1,-1,"0000110",D1:D10)

Where range D1:D10 contains the list of holidays.

## Tips & Tricks 77 - Inserting picture in the comments box

By |Saturday, February 07th, 2015|Categories: Tips and Tricks|Tags: , , |0 Comments

The below discussion is for Excel 2013. If a cell is selected and it has comments, the comments will be displayed. Sometimes, there may be a need to display picture when you select a cell. I answered this question on Microsoft Community Forum and I have decided to reproduce it here.

1. Right click the cell > Edit Comment
2. Now, you need to right click on the border of the comments box. Do not select the comments inside the box and choose Format Comment. Since, you are inserting picture, hence you should not have comments in the box, anyway. So, there is no question of selecting comments inside the box. Once again, I will repeat that RIGHT CLICK ON COMMENTS BOX BORDER AND SELECT FORMAT COMMENTS.
3. Now, you will get Format Comments box and you need to select Color and Lines tab.
4. Click on Color: box and select Fill Effects.

5. When you click Fill Effects, choose Picture tab and select picture from there. By default, it starts connecting online to select picture. Most probably, you would like to select a picture on your computer. You may like to choose Work Offline here.

6. Now, you can have effect of picture in your comments like below -
