+        Since NumPy uses ``timedelta64`` objects for its time operations, converting
+        a pandas ``Timedelta`` into a NumPy ``timedelta64`` provides seamless
+        integration between the two libraries, especially when working in environments
+        that heavily rely on NumPy for array-based calculations.
