When does Naruto shonen jump end and shippuden begin


Just would like to know when or if the two series overlap and if so when
should I watch Shippuden




At age 12 or 13, Naruto goes with Jiraya to train and become stronger. That is
when the Naruto series ends. 3 years later, Naruto returns to Konahakagure,
and Shippuden starts.
