[1] Times up to 27 March 2004 (third and fourth rounds) were CET (UTC+1), and thereafter (quarter-finals to final) CEST (UTC+2).
The schedule was as follows (all draws were held at the UEFA headquarters in Nyon, Switzerland).
The team that scored more goals on aggregate over the two legs advanced to the next round.
If the aggregate score was level, the away goals rule was applied, i.e., the team that scored more goals away from home over the two legs advanced.
If away goals were also equal, then thirty minutes of extra time (two fifteen-minute periods) was played.
In the final phase the silver goal system was applied, whereby the team who leads the game at the half-time break during the extra time period would be declared the winner.
If no goals were scored during extra time, the tie was decided by penalty shoot-out.
In the final, which was played as a single match, if scores were level at the end of normal time, extra time was played.
If, on completion of the first period of extra time, one of the teams had scored more goals than the other, the silver goal rule was applied, i.e., the match ended and that team was declared the winner.
The draw for the fourth round was held on 4 March 2004, 14:00 CET.
A draw was held on 4 March 2004 (after the fourth round, quarter-final and semi-final draws) to determine the "home" team for administrative purposes.
