I'm sure the OP has reasons to reorder the months as shown but his data
seems to argue that he shouldn't split the wet season (Oct - Apr) but
should, instead, tack the 1972 months (Jan - Aug after the 1971 months
(Sep - Dec).

I have data that looks like below and I would like to re-order the values within the

Nov-71

Jan-71
Feb-71
Mar-71
Apr-71
May-71

Is there any way I can order the column in my own fashion and just move Sep-Dec
to the beginning of each year? I am planning on doing some time series analysis
with this data and think that the order of months is very important for the
time series. I appreciate any suggestions and thank you in advance.
