Monthly Data

My utility company reads my meters on the 8th of the month and sends me a bill labeled for that month. Therefore my September bill is actually for the 9th of August to the 8th of September. This makes it difficult to compare what the utility company has for my consumption and production with what PVOutput shows. Is there a way to adjust my PVOutput months to match my utility billing months?
