The Scottish champions have already postponed their Scottish Premiership meeting with Kilmarnock on January 11 and signed up to take part in the Antalya Winter Cup, which runs between January 8 and 12.
Turkish sides Galatasaray and Trabzonspor and recent Champions League opponents Ajax are the other sides also involved.
Celtic will face Trabzonspor - whose squad includes former Hibernian defender Sol Bamba and ex-Chelsea winger Florent Malouda - in the second semi-final on Thursday, January 9.
Ajax and Galatasaray open the competition the day before, with all games taking place at the 7,100-capacity Akdeniz Universitesi-Stadion in Antalya.
The two losing semi-finalists will meet in a third-place play-off on Saturday, January 11, with the winner to be decided 24 hours later when the final takes place.
If Neil Lennon's side match Ajax's result, it will set up their third meeting of the season. Celtic registered their only group stage success when they beat the Dutch champions 2-1 in Glasgow but they lost the return 1-0 in Amsterdam, both matches marred by crowd trouble inside and outside the stadiums.
