what kinds of information can you remember for a calendar? year?date?month?weekdays?leapyear?... try to find these from the image
the code is:
>>> import calendar
>>> for year in range(1006,1997,10):
if calendar.monthrange(year,2)[1]==29:
temp=calendar.monthcalendar(year,1)
if temp[4][0] == 26:
print year

1176
1356
1576
1756
1976

check what happened on the Jan. 27 in these years respectively...
the final answer is 'mozart.html' from 1756-1-27  Wolfgang Amadeus Mozart, Austrian composer (d. 1791) ...
In my perspective, it is a bit hard to get in this way...
