It appears here to be since 1969-12-31, or since 1970-1-1 but then starting with 1 instead of 0. And your 59 is wrong if the others are deemed to be correct. Depending on what you want you have to add 1 to the following solution import datetime startdate = datetime.date(1970, 1, 1) enddate = datetime.date(1970,3,1) timediff = enddate - startdate print timediff.days result: 59 -- Piet van Oostrum <p...@vanoostrum.org> WWW: http://pietvanoostrum.com/ PGP key: [8DAE142BE17999C4] -- http://mail.python.org/mailman/listinfo/python-list
