I'm not a buyer so I'm not 100% sure which months are given to which seasons. For instance, Feb, Mar, & April may be for Spring but what about Spring 1 and Spring 2? I guess it also depends on the main product and region? But let's say its an apparel brand that sells in a climate that experiences all seasons (northeast of the United States, for example). How are the seasons normally split up? Winter I? Winter II? Spring I? Spring II? ... and so forth? Thanks in advance!
