44 Weeks in a Year

Take into account that, with a few exceptions, purchases are not made linearly throughout the year.

It is easy to fall into the trap of forecasting activities in terms of days or weeks of effort, with each week during the year being treated as equal.  This assumption is rarely true.  For example, consider the available productive time during Thanksgiving week in the US versus that same week in another country that does not celebrate Thanksgiving.  Many businesses purchase goods and services nonlinearly based on the calendar of their customer’s habits.  The year generally does not have fifty-two equal weeks.  The variances can have a significant impact on a strategic plan.
