Hi,
The cutoff year is for use for a date value with only 2 digits for year so as to ensure that there will not be mixed ups. So a 01/01/10 will be taken as 01/01/2010 and not 01/01/1910. At the same time, the default calculation for dates uses the 1960 date as the point of references. Thus the difference.

Subject: default date value, SAS certification book
The book: SAS base programing certification, 2nd ed.
On p582, it says: A sas date value is the number of days from January 1,
1960, to the given date.
This saying seemly suggest that the default value of the yearcutoff should
be 1960.
But, on p588, it says the default YEARCUTOFF= value is 1920.
Can anyone explain this to me? Thanks a lot for your time.
