How to use day of the week and the day of the month to get year in python?

for example how would you get "2016" from

Fri, Feb, 19 ?

I have a database from somewhere that has entries from the last 4 years but only lists dates as day of the week and day of the month, and I need to get the year from each. There should not be any repetitions because there is only four years of data, and date & day of the week alignments do not repeat in that timeframe.

This is just slightly different from @zondo's answer who beats me to it, but I'll put this up anyway because I prefer not to have the .year at the end of a long expression:

year = next(y for y in range(2013, 2017) if datetime.date(y, 2, 19).weekday() == 4)

How about this:

import datetime

year = next(date for year in (2013, 2014, 2015, 2016)
            for date in (datetime.date(year, 2, 19),)
            if date.weekday() == 4).year
