# dateIncrement

How far into the future/past the calendar navigates when prev/next is executed.

<div class='spec'>

[Duration](duration-object.md)-ish input

</div>

Determines how far the calendar will jump when the user presses the prev/next buttons in the [headerToolbar](headerToolbar.md) or when the [prev](Calendar-prev.md) or [next](Calendar-next.md) methods are executed.

When using a standard view, it is unnecessary to specify `dateIncrement`.

When using a [Custom View](custom-view-with-settings.md) with a specified `duration`, the `duration` value will be the default for `dateIncrement`.
