Change the timescale in a view

Some views, such as the Gantt Chart and the usage views, have a timescale that appears above the chart or timephased portion of the view. You can show up to three tiers of timescale in each view and you can format each tier individually. For example, you can specify the time units, date labels, alignment, and other formatting options.

You can also customize the timescale in the Calendar view to meet your needs. For example, you can display 5-day weeks or 7-day weeks, small representations of next and previous months, or days of the week spelled out.

Note: This topic describes how to change the timescale for views. It does not describe how to change resource or task calendars used to schedule your project work.
