Apparently, there’s a special app called “Kpop Soldier Star Calculator” just for this purpose. After you sign up on the app, pick SeungGi’s picture to get started. (The remaining time on the counter is slightly off since I’m in a different time zone. 😛 )
So according to this app, SeungGi’s training completion ceremony will be held on March 16. He’s currently a Private, but will be promoted to Private First Class on May 1, 2016 (which is 87 days from now). He will be promoted to Corporal on December 1, 2016, then Sergeant on July 1, 2017, before he gets discharged on October 31, 2017.
SeungGi ya, fighting! Stay safe and healthy!
