SAS. Why "Jan 11 2002" == "88399", according to documentation?
I was reading the [dates documentation][1], but couldn't understand how SAS handled the dates:
On [SAS website][2] they explain that `Jan 1 1961` is 366, which makes sense : this is the number of days from `Jan 1 1960`.
Further they convert `Jan 11 2002` into `88399` WHY ? This does not make any sense . The number of days from `Jan 1 1960 ` to `Jan 11 2002 ` is NOT 88399, it is around 16K !!!
**Where do they get the 88399 ?**
Thanks in advance !
