For those of you who are actually in the retail business, you might be interested to know that the National Retail Federation has put out new 4-5-4 calendars for 2009 and 2010.
A 4-5-4 calendar basically helps retailers make accurate comparisons from year to year, accounting for the differences in the number of weeks in a given month (some years there are four weeks in a month and some years there are five). You can find the calendars on the NRF's Web site here.
