31.1 Movement in the Calendar

Calendar mode provides commands to move through the calendar in logical units of time such as days, weeks, months, and years. If you move outside the three months originally displayed, the calendar display scrolls automatically through time to make the selected date visible. Moving to a date lets you view its holidays or diary entries, or convert it to other calendars; moving by long time periods is also useful simply to scroll the calendar.

Calendar Unit Motion:    Moving by days, weeks, months, and years.
Move to Beginning or End:    Moving to start/end of weeks, months, and years.
Specified Dates:    Moving to the current date or another

specific date.
