When is Jeonghan going to the military??

In the article

On the 12th, Pledis Entertainment, Seventeen's agency, stated, "Jeonghan is scheduled to fulfill his military service in the second half of this year," and "Most of the content that could be prepared in advance has been filmed, but he will not be able to participate in the 12th mini album promotions and world tour schedule scheduled for October of this year."

If you're not promoting the album in October, are you going around October...???
