Quanto tempo leva para minerar um bitcoin?

I'm curious to know, just how long does it actually take to mine a single Bitcoin? I understand that the process involves complex mathematical equations and a lot of computing power, but I'm looking for a more specific answer. Is it measured in hours, days, weeks, or even months? And does the time it takes vary depending on the current mining difficulty and the amount of hashing power being directed towards the network? I'm eager to understand the ins and outs of this fascinating process.
