Calculus was an absolute mind-fuck for my algebra centered mind when I got to college. Took me probably two full months before it clicked and I basically settled on "this is still math, but it's completely different rules and the old rules don't apply at all."

That doesn't actually sound like very long. I can easily image it taking more than two months to learn a new programming language, or how to build your own radio. Pretty much any nerd activity will take some time to get into.
