Goodnight is a smart guy but a birth year of 1961 would have had him
starting to code SAS when he was around 7.
I assume that you are referring to the Yearcutoff option. Take a look at
the following from the online docs. It should explain things better than I.
The YEARCUTOFF= value is the default that is used by various date and
datetime informats and functions.
If the default value of nnnn (1920) is in effect, the 100-year span begins
with 1920 and ends with 2019. Therefore, any informat or function that uses
a two-digit year value that ranges from 20 to 99 assumes a prefix of 19.
For example, the value 92 refers to the year 1992.
The value that you specify in YEARCUTOFF= can result in a range of years
that span two centuries. For example, if you specify YEARCUTOFF=1950, any
two-digit value between 50 and 99 inclusive refers to the first half of the
100-year span, which is in the 1900s. Any two-digit value between 00 and
49, inclusive, refers to the second half of the 100-year span, which is in
the 2000s. The following figure illustrates the relationship between the
100-year span and the two centuries if YEARCUTOFF=1950.
If , instead, you are referring to Date = 0 in the SAS scheme of counting
dates,
1 data;
2 date = 0;
3 format date mmddyy10.;
4 put date;
5 run;
01/01/1960
Which is the start of the decade in which SAS was written.

Hi Everybody,
This is a light question when some of the SAS/Statistics questions on this
listserve considered..
I want to know what the significance of year 1961 in SAS cutoff time
codes(?). For such a long time I though it was the birth year of Jim
Goodnight.. I found out that it is not!
Thanks,
Fay
