SSRS Date Format Issue

Formatting a date can be a common requirement in SSRS reports. Though, we have few built-in methods to play around, it is best if you can do it using format options within the textbox properties. I am just going to demystify something in it.

How to get there;
Right click the text box > Select text box properties > select Number tab > select Date

Now you see this;

Now you can select any format you need.. and that’s the short and sweet way.

Anyway, as I highlighted, I noticed two separate formats which look likes same.
(Do you see what I see?). Now what does this means?

First one shows date as “1/12/2012”
While
Second one shows date as “01/12/2012”

Two different formats, though little unclear.
