Highlight due dates in Excel – Show items due, overdue and completed in different colors

Highlight due dates in Excel – Show items due, overdue and completed in different colors:
Congratulations to you if your job does not involve dead lines. For the rest of us, deadlines are the sole motivation for working (barring free internet & the coffee machine in 2nd floor, of course). So today, lets talk about a very familiar problem.
How to highlight due dates in Excel?
The item can be an invoice, a to do activity, a project or anything.

The problem – Highlight due dates in Excel

Lets say you work at Awesome inc. and you have list of to-do items as shown below.
And your problem is,

• Highlight items & due dates, subject to these conditions
  
  
• And of course start working on the items that are due

The Solution – Conditional Formatting

As you can guess, highlighting the due items is easier than actually doing them. First lets look at the solution and then learn why it works.
Lets assume that,

• The data is in the range – B6:D15, with Items (column B), Due date (C) and Completed?(D)

Solution

1. Select the entire range (B6:D15) and from home ribbon select conditional formatting
2. Select New rule
3. Select the rule type as “use a formula…”
4. To highlight completed activities
5. Now write =$D6=”Yes”
6. And set font color to dull gray from formatting button.
   
   
7. To highlight items due in next 7 days
8. Add one more “use a formula…” rule
9. Write =AND(MEDIAN(TODAY()+1,$C6,TODAY()+7)=$C6,$D6<>”Yes”)
10. And set fill color to orange.
11. To highlight items already due
12. Add one more rule
13. Write =AND($C6<=TODAY(),$D6<>”Yes”)
14. And set fill color to red & font color to white.
15. Done!

Now, the items will be highlighted based on the current date (TODAY)  and change colors as you make progress.

Why does it work? – Explanation

At this point you may have 2 burning questions.

1. Why does this work?
2. How the heck am I supposed to ship 100 units of smile.

Lets talk about the solution & understand why it works.
Understanding the highlighting conditions
We have 3 conditions in our highlight table (shown above).

• If done show in dull gray color
• If not done & due in next 7 days show in orange color fill.
• If not done & already due show in red fill, white color

If done:
The first condition is easy to check. We just see if a todo item is completed and then highlight the whole row dull gray color. So we write =$D6=”Yes” as the condition. We use $D6 (not D6) because we want Excel to look at column D (completed?) even when we are highlighting other columns (B – Item, C – Due date).
If not done & due in next week:
This is tricky. We need to check,

If completed is not yes

AND

If due date is with in next week

So we start with an AND formula. We write =AND($D6<>”Yes”

Then to check if due date is in next week, we use MEDIAN formula, like this MEDIAN(TODAY()+1,$C6,TODAY()+7)

So the condition becomes =AND(MEDIAN(TODAY()+1,$C6,TODAY()+7)=$C6,$D6<>”Yes”)

If already due:

This is another simple AND formula =AND($C6<=TODAY(),$D6<>”Yes”)

Remember:

We need to use $D6 & $C6 (instead of D6, C6) because we want Excel to check Completed & Due date columns. By removing the $ Excel will check relative columns and the conditions would not work!

Now that we understand how this works, give me a big smile. And repeat that 99 more times & you know how to ship 100 smiles

Note: I use random formulas to generate due dates & completed values. Press F9 to get fresh set of dates. Start typing your own values to remove formulas.

How do you handle dead-lines?

Do you use conditional formatting to see which items are due? I use conditional formatting for this all the time. What techniques you use? Is your dead-line criteria very different than shown above? Please share your tips & ideas with us using comments. I would love to learn from you.
