Deduce the year from day_of_week

Suppose we know: it happened on Monday 17 November. Question: what year was it?

import datetime as dt

for i in [ dt.datetime(yr,11,17)  for yr in range(1970,2014)]:
    if i.weekday()==0: print i

1975-11-17 00:00:00
1980-11-17 00:00:00
1986-11-17 00:00:00
1997-11-17 00:00:00
2003-11-17 00:00:00
2008-11-17 00:00:00

Or suppose we want to know all mondays of November for the same year range:

for i in [ dt.datetime(yr,11,1) + dt.timedelta(days=dy) 
           for yr in range(1970,2014) for dy in range(1,30)] : 
    if i.weekday()==0: print i

1970-11-02 00:00:00
1970-11-09 00:00:00
1970-11-16 00:00:00
