Bug summary

When you make a plot with theConciseDateFormatter that shows on the x axis days and months theoffset_string also shows the month (with the year) which I think is redundant because you only need the year

Code for reproduction

importmatplotlib.pyplotaspltimportmatplotlib.datesasmdatesimportdatetimefig,ax=plt.subplots()d1=datetime.datetime(1997,1,1)d2=d1+datetime.timedelta(weeks=520)locator=mdates.AutoDateLocator()formatter=mdates.ConciseDateFormatter(locator)ax.xaxis.set_major_locator(locator)ax.xaxis.set_major_formatter(formatter)ax.plot([d1,d2], [0,0])ax.set_xlim(d1,d1+datetime.timedelta(weeks=3))ax.set_xlim(d1+datetime.timedelta(weeks=1),d1+datetime.timedelta(weeks=10))plt.show()
