What is the 4-5-4 Calendar: The 4-5-4 Retail Calendar divides the year into quarters with the first and last month of each quarter consisting of 4 weeks each and the middle month of each quarter consisting of 5 weeks. Each calendar month begins on a Sunday and ends on a Saturday. Each month has the same number of selling days as the same month last year. For example, March has 5 perfect weeks every year, 5 Saturdays, 5 Mondays and so on.
Why was it created: The problem with regular calendars is that the number of weekends in a month vary year to year. Weekends constitute a large percentage of sales. With a 4-5-4 calendar, that was developed in the 1930s and is widely followed by retailers today, retailers can more easily compare year on year sales. The layout of the calendar lines up holidays and ensures the same number of Saturdays and Sundays in comparable months. Hence, like days are compared to like days for sales reporting purposes.
I am looking for anyone out there that may have created a 4-5-4 Retail Calendar template for Sharepoint. I would love to hear about your experience using it.
