you can use the select tool with python. It's easier if you first copy the joined attributes to your feature class table, but not necessary.
here is a python snippet (assuming you work with a shapefile)
for year in range(2000,2015):
arcpy.Select_analysis(fc, fc[:-4]+str(year)+".shp", """ "Start" = """ + str(year) )
this query is designed for a numeric field. For text field you should put it between ' 's
""" "Start" = '{}' """.format(year)
