New player's free month

So, I got a friend who'd like to try FFXIV but he's not sure should he wait for 1.20 or start now... It depends on the free month. Does he get a free month after billing starts again or does that free month count on this free time that's currently going?

if he gets it today, he probably won't be getting an extra free month. I don't know what'll happen if he does it once they start billing though
