Answer 1

I ran into similar problems. You most likely have a lot of NaTs.
I removed all my NaTs and then performed the join and was able to join it.

      df = df[df['date'].notnull() == True].set_index('date')
      d = d[d['date'].notnull() == True].set_index('date')
      df.join(d, how='right')
