To use DATEDIF in Excel, you first need two dates that you wish to compare. Suppose A1 has the start date, and B1 has the end date. To calculate the difference in days, use `=DATEDIF(A1, B1, "d")`. For months, substitute "d" with "m", and for years, use "y". Remember, DATEDIF calculates full periods only, so for complete months or years between dates, this function is incredibly useful. It's especially helpful in calculating ages, service tenures, or any period between two specific dates.
