     Notes
     -----
-    Of the four parameters: ``start``, ``end``, ``periods``, and ``freq``,
-    exactly three must be specified.  Specifying ``freq`` is a requirement
-    for ``bdate_range``.  Use ``date_range`` if specifying ``freq`` is not
-    desired.
+    Of the four parameters ``start``, ``end``, ``periods``, and ``freq``,
+    at least two and at most three must be specified. You cannot specify
+    all four parameters together. If ``freq`` is omitted, the resulting
+    ``DatetimeIndex`` will have ``periods`` linearly spaced elements between
+    ``start`` and ``end`` (closed on both sides).
