Hi,

I have just run a test in SAS9.4 M5 and it appears that the 29th February 4000 has disappeared. I noticed this as I have been required to compare a SAS program and a T-SQL program that are calculating the number of days between two dates, two of which are 04MAR2010 and 04MAR5310 - undoubtedly the result of a data entry error but nevertheless...

The SAS INTCK function returns 1205299 days but the T-SQL DATEDIFF function returns 1205300 days which I have tracked down to SAS not acknowledging the existence of 29th Feb 4000.

Thanks,
Mark
