Prism Administration Console Guide
Global Preferences > Season

Retailers can configure Prism to adjust the price of an item based on seasonal demands. An advantage of seasonal pricing is that the price for an item is set high during periods of high demand and lowered as seasonal demand drops off to clear inventory to make room for the current season's products. Pricing for seasonal holiday products, such as those connected with Thanksgiving and Christmas, are frequently reduced the day after the holiday to clear inventory.
In this area, define a set of non-overlapping seasons. When combined with price levels and markdowns, the defined seasons allow for "seasonal pricing" in which different prices are used for different seasons. For each season, define a three-letter season code, a season name, and define the Start and End dates.
