Seyyid Ibn Tawus in Misbah Al-Zair says the best day to visit the dead is Thursday, but if you cannot do it on a Thursday, do it on any day you can.

Upon reaching a grave of believer, face qibla and place your hand on the grave. Then recite Surat Inna Anzalna (Al-Qadr) seven times, Al-Hamd. Al-Tawheed, Al-Falaq, An-Naas and Ayatul Kursi. When a person recites Suratul Qadr for a dead Momin seven times, Allah creates an angel to sit beside the dead person and protect the dead person from all afflictions until the day of judgement.
