There's no "one right time" to make the transfer. You definitely want to wait a few days after the active fermentation has subsided, but you could wait just a few days or a week or two. So, don't sweat the countdown too much.
I know you're probably anxious to taste the fruits of your labor, but, unfortunately, brewing is a hobby where patience is rewarded far more than haste. That's why people often have 3 or 4 batches in various stages of brewing at a time!
