Lets start the week with a quick tip.
Lets say you have a list of employees and their birthdays. Now you want to sort this list, based on their birthday, not age. How would you do it?
Sorting by day and month alone:
- Add a column next to original dates. Lets call this Birthday.
- Then, calculate birthday in current year for everyone.
- Assuming DOB is in B1, Formula for birthday (in current year) would be,
=DATE(YEAR(TODAY()),MONTH(B2),DAY(B2)) - This formula gives you a date which has same year as TODAY(), same month & day as original date.
- Then, fill down the formula for all rows.
- Now sort this new column (Birthday) in chronological order.
- You are done!

Note: if you are using tables, then use this formula.
(Assuming original date is in DOB column),
=DATE(YEAR(TODAY()), MONTH([@DOB]),DAY([@DOB]))

More Sorting Examples:
- Sorting sideways
- Sorting in Olympic medals table style, Formula 1 racing style
- Rounding and sorting data
- Checking if a list is sorted using formulas
- Sorting text values using formulas
Homework for you:
If you think sorting by birthdays is easier than eating a birthday cake, then I have a challenge for you. Assuming a list of data of births is in the range A1:A100, write a formula to find how many birthdays are in this month?

yes, I use watches in excel vb
Dear Chandoo,
This is a quite useful for myself. I highly appreciate your efforts for acquainting us with this value adding and time saving tip.
I'll admit it, I never saw this feature before. I was familiar with using Watch Window in VB, but not in workbook. I'll definitely use this in future when building dashboards!
it was always great reading your blog, one thing that i want to know, which tool you are using to create such gif image?
