In La Liga, the exact day and time of the match are not announced until about 10/15 days before the match is played. Until then, a text appears on the match file saying "date and time pending confirmation." Once the match is confirmed, the text disappears. In the CHL, both in the knockout phase and in the other stages, the date of the match is announced on the same day as the draw. CHL matches at Camp Nou start at 7:00pm or 9:00pm.
In the Copa del Rey, the date is confirmed a few days after the draw.
