# Date is encoded. Can't figure it out.

I have dates that are encoded in a MSSQL db but we need to crack the date encoding to build some software that can plug-in to the db(which belongs to us).

01/20/2011 = 76724

03/08/2011 = 76771

10/11/2011 = 76988

11/10/2011 = 77018

Any ideas on the encoding being used?

Looks to me like it's just the number of days since $76724$ days before 1/20/2011. Microsoft Excel can do the conversion pretty easily. –  Qiaochu Yuan Dec 22 '11 at 19:13
Why did you think these dates were encoded? Encoded data should look random, not regular as this does. –  lhf Dec 22 '11 at 19:22
