The actual date Youtube will send your payment to your bank account
I myself have asked this question when i was waiting for my payment to arrive. What date will Youtube send my payment. Let me keep this post as shortest as possible.
You must reach 100 dollars before the 15th of every month and on that same month you reached 100 dollars before 15th, Youtube will send your payment to your bank account on 21st of that month.
Assuming you reached 100 dollars on 15th of September 2016, Youtube will send your payment to your bank account on 21st of September 2016.
Check your mail which you used for your adsense account on 21st for a message like this below:
