The ToDateTime method is useful because it can convert any date in the current calendar to a Gregorian calendar date. The Gregorian date can subsequently be used, for example, to compare dates in different calendars or create an equivalent date in a particular calendar.

The following code example demonstrates the field, property, and method members of the PersianCalendar class.
