SQL - is not null syntax help - SQL Server 2005

Hello experts,
I have the below snippet of code that is causing me troubles.

declare @HGA1C varchar(30)
set @HGA1C= ''

if (@HGA1C is not null or @HGA1C <> '')
set @HGA1C = CONVERT(VARCHAR(10), convert(datetime,@HGA1C, 101),101 )

select @HGA1C

When I run the above code it returns '01/01/1900'

However, I would like it to simply return a blank segment.  Is there any way to code around this?  My problem is that most of the time this @HGA1C variable HAS a value, but sometimes it is blank - and my if statement above almost seems to be ignored.  

Thanks!

Try Change
if (@HGA1C is not null or @HGA1C <> '')
to
if (@HGA1C is not null and @HGA1C <> '')

the main issue, I noticed is the above.

always the code inside 'if' loop executes and returns the default date of 'datetime' datatype - 01/01/1900

I'm trying, I really am. But I've seen so many wrong approaches involving date(time) boundaries I despair about my inability to explain it. I've seen quite a few recently that define a non-leap year as 364 days, or 366 days and the list goes on. …
