Ahly and Zamalek have been informed by the Confederation of African Football (CAF) of the final dates for their kick-off of the Champions League group stage round.
Zamalek will start their group B matches against Caps United of Zimbabwe on Friday 12 May at home in Borg El-Arab stadium in Alexandria.
One day later at the same arena, Ahly who are competing in group D, will host Zanaco of Zambia.
In the draw held last week, Ahly and Zamalek avoided having to face one another, having both been placed in pot 1 alongside South Africa's Sundowns and Tunisia's Etoile du Sahel.
Ahly, the record holders of eight Champions League trophies, sealed their place in the last-16 group stage following a 1-0 win on aggregate over South Africa's Bidvest Wits in late March.
Five-time champions Zamalek reached the same round after a 5-3 win on aggregate over Nigeria's Enugu Rangers International FC. They are bidding for their first title since 2002.
