As pointed out previously, 33824 
is (almost) 8 August 1992 expressed as days after 
1 January 1900: 

. di mdy(8,8,1992) - mdy(1,1,1900) 
33822

In any case, Stata uses an origin 
of 1 January 1960, so to adjust 
your dates to Stata's origin 
I derived the difference between 
origins: 

. di mdy(1,1,1960) - mdy(1,1,1900) 
21914
