Shavuot is often regarded as the Cinderella of major festivals that often slips by unnoticed. While shuls may be greened up and cholestorol levels rise with the proliferation of cheesecake, there are no home practices associated with it such as succah or Seder.
But Shavuot has begun to enjoy a revival in recent years. More synagogues than used to be the case will stage a nocturnal study session, a tikkun leil Shavuot, tomorrow night to celebrate the joy of study. Even secular groups in Israel hold learning get-togethers.
If you can't find a local tikkun leil to go, here's a DIY option. You can download this little study pack from Limmud and have a discussion among family and friends.
