Specifying the Smallest Period of Time

After the number of years is defined, the Initial Time Period Setup Wizard divides years into months or weeks. Selecting Months or Weeks defines the smallest native period in the model, which helps to construct the calendar for that model.

Caution:

Once specified, you cannot change the type of calendar that is used by a model.

To define the smallest period of time:

1. Select an option:

   • Months—Enter data by month. No weekly data exists.

   • Weeks—Enter data by week. Monthly aggregates are calculated.

2. Click Next and see the appropriate topic:

   • For Months, see Creating Monthly Time Periods.

   • For Weeks, see Handling Extra Days in a Year Made of Weeks.
