Hmmmm ... I wonder what the style police will have to say about that
little lot :-)

# Look, Ma, no 3rd party modules!
import datetime
for start in range(1, 8):
    print
    d1 = datetime.date(2009, 3, start)
    day1 = d1.toordinal()
    dow1 = (day1 - 1) % 7
    for delta in range(8):
        d2 = datetime.date(2009, 3, start + delta)
        day2 = d2.toordinal()
        dow2 = (day2 - 1) % 7
        workdays = (day2 + 7 - dow2 - day1 + dow1) // 7 * 5 - min
(dow1, 5) - max(4 - dow2, 0)
        print d1, d2, dow1, dow2, workdays
# Assumes both endpoints are included e.g. Mon 2 March to Tue 3 March
is 2 work-days.
