Publishing app to App Store

No. It is $119 per year. That 2 day timeframe probably refers to an average time in review. But that's average, certainly not maximum. There is no way it would take a year. If it takes a week, then Apple is probably just hoping you'll go away on your own. Generally speaking, if you have an established app then an update should take from 6 hours to 2 days in review. New apps might take longer. If your app is a scam, or something closely associated with scams, then you might never get approved.

Can you provide some additional context? Are you asking how long it takes to click the button? About 0.5 seconds. Are you asking how long it takes to develop an app? Anywhere from 2 weeks to 4 years.

Same for cost. Are you asking how much the Apple Developer program costs? $119 CAD + tax depending on where in Canada you are. Or are you asking how much it costs in time and effort? Depends on what your time is worth. If we assume a baseline of $50/hour, then that would be anywhere from $3600 to $360,000.
