This change of match-date is subject to Football League approval.
The game was originally scheduled to take place a day later on Saturday 4 April 2015.
Following the change to Good Friday, City's match at Doncaster will now kick off at 7:45pm.
With the Bantams due to play Preston North End on Easter Monday (6 April 2015) and Doncaster set to face Sheffield United on the Tuesday (7 April 2015), the movement of the above fixture will now give both sides an extra day to prepare for their secondary Easter weekend matches.
The re-arranged Doncaster game is the first match to be changed from the club's original fixture schedule given to them by the Football League just over a week ago.
The fixture at Doncaster next April will be City's first league visit to the Keepmoat Stadium since its creation back in late 2006.
City's only previous match there to date was a Football League Trophy tie played in September 2007.
