Note: Please read this guide detailing how to provide the necessary information for us to reproduce your bug.

Code Sample, a copy-pastable example

>>> from pandas.tseries.offsets import *
>>> fq = LastWeekOfMonth(1)
>>> pd.date_range('2018-04-01', periods=1, freq=fq)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/miniconda3/envs/test37/lib/python3.7/site-packages/pandas/core/indexes/datetimes.py", line 1077, in date_range

ValueError: N cannot be 0

Problem description

The output of date_range with period = 1, freq = LastWeekOfMonth should not raise a error, since other freq like WeekOfMonth gives a normal output with period = 1.

Expected Output

DatetimeIndex(['2018-04-30'], dtype='datetime64[ns]', freq='LWOM-MON')

Output of pd.show_versions()
