Lag BaOmer is a day of salvation for everything. (Shaar Yisaschor)
Lag BaOmer is Saturday night and Sunday. See Zchus Avos for segulas for Lag BaOmer, here for the story of Rabbi Shimon bar Yochai, and here to send a prayer to Meron and to donate food and mashke to the chassidim who will be praying, dancing and celebrating throughout the weekend Rabbi Shimon's kever.
