Hi!
Here's an idea.
Assume dates are in column A, A1:An.
You need 3 helper columns: B, C, and D.
In B1, C1 and D1 enter these formulas respectively:
=MONTH(A1)
=DAY(A1)
=YEAR(A1)
Select cells B1, C1 and D1 and copy down to the end of the list of dates in
column A.
With that range still selected do a Copy/Paste Special/Values
Now, select the entire range A1

n
Sort by column B then by column C then by column D.
When done and satisified, get rid of the helper data.
