I want to know the answer to the following question:
When did Madonna embark on the Rebel Heart Tour?
All the background I'm provided with is that "From September 2015, she embarked on the Rebel Heart Tour to promote the album; the tour ended in March 2016 and traveled throughout North America, Europe and Asia and was the singer's first visit to Australia in 23 years, where she also performed a one-off show for her fans.". Is that enough to answer the question?
