UDF stands for a User Defined Function. This is one which you write
yourself in VBA and can use from your own worksheet as if it were one
of Excel's functions. Let's say you had a UDF called
"Calc_time(cell_ref1, cell_ref2 )", then you would enter this formula
in a cell:

=Calc_time(A1,B1)

and it would return the result of whatever it calculates.

Hope this explains.
