bit less than that lol
if it goes to plan it should take:
4 groups play their matches per day so thats
8 group matches in 2 days so
12 days for the group stage
half the round of 16 matches played per day so
4 matches per day
2 days
half the quarter finals played per day
2 matches per day
2 days
all the semi finals played
1 day
final = 1 day
adds up to 17 days.
everyone should have a time of day that they can play the other person surely.
