This was the time at which the FA Cup semi-final between Liverpool and Nottingham Forest was abandoned on the same date in 1989 because of the crush which took place at the Leppings Lane end of Hillsborough, resulting in 96 fatalities among Liverpool supporters.
Liverpool and the Hillsborough Family Support Group have asked Wednesday not to hold a formal memorial service at Hillsborough on the 20th anniversary because an official event is taking place at Anfield on April 15, but Owls' club staff will observe a corresponding two-minute silence.
Sheffield Wednesday chairman Lee Strafford said: "The thoughts of everyone associated with Sheffield Wednesday are with the families of the 96 Liverpool fans who lost their lives on April 15, 1989, and what happened that terrible day is something that should never be forgotten.
"The Hillsborough disaster will always be remembered for the tragic loss of so many lives and it had a profound impact on countless people and families, not only in Liverpool, Sheffield and Nottingham, but across the country and overseas as well. Our sympathies remain with the loved ones of those who lost their lives 20 years ago."
Sheffield Wednesday will provide access to the Hillsborough memorial on Parkside Road as well as the Leppings Lane end at Hillsborough for those wishing to pay their respects at the stadium on the 20th anniversary. There will also be a minute's silence prior to the Owls' match against Southampton on Saturday, April 18.
