+        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.
