How to keep all monday from a datetime

Question

I'm looking to keep all the Monday from a df. I have a date column with for exemple value like this 2014-01-02 00:00:00+00:00.

So far i have succeeded to extract the days of the week like this (0 = monday):

date = pd.date_range('Beginning', 'End', freq='D').to_series()
date = date.dt.dayofweek

I'm stuck because I have trouble to keep only the Monday. Any idea how I should do? (Maybe the problem come from the code above)
