If you already have a solid understanding of different coordinate systems, matrix algebra, series, trigonometry, and a willingness to accept theorems without proof, then not every long at all.
The concepts are rather straight forward if you have prerequisite understanding. However, being able to solve actual problems through application of calculus is a whole different barrel of worms.
Read a concept, practice some examples, solve some conceptual problems on your own. I'd say reasonably, it should take about an average 45 mins per concept to get a good grasp on each topic. This is again assuming you have all of your trig identities and algebraic solving skills down pat without any need for review and that you can be somewhat creative with manipulating transcendental expressions. You could memorize integral tables but that isn't "learning calculus". If you can solve any partial faction decomposition problem, trigonometry proof, and are an exponent with logarithm and exponential identities, than setting up integrals will be a breeze.
So from the definition of a derivative to Stokes Theorem, without any Real Analysis or Proof of Theorems, including integrals with hyperbolic and applications for integration requiring setting up polar coordinates, etc I'd say about 60 hours of study and practice at an absolute minimum, anything less I'd doubt as humanly possible.
But for most people, three semesters.
