If something is recent, it happened in the immediate past or not long ago. You are a recent fan of yoga if you just started liking it in the past week or two.
If you talk about something that happened in recent months or years, it means the last one to three months or years. Otherwise, recent means new or just happened. It’s particularly useful when you don’t know exactly when something happened, but you know it wasn’t long ago. Perhaps you have been a recent guest star on a show, and your recent movies have been very successful. You know it wasn’t long ago at all and you are still a star!
