The last twenty days of Febuary will slow down for most followed by a pick up in the first two weeks of March.
Then once again expect a slow down in the first two weeks of April followed by a strong increase after April 17th.
Things will remain pretty strong with the exception of the first week after Fathers day and the first two weeks of September.
The beginning of October this year should be a very strong start to Xmas. These are just general estimates that can be changed by many outside factors such as a bad presidential election or if you provide a product or service that is seasonal.
Also on the internet, buying trends or peaks in buying habits end a few days before the peaks of the retail stores.
